Document directory shape and key files; let `git ls-files` be authoritative for the rest. +- **Per-spec changelog sections** ("Spec 0042 added X").

Looks fresh; ages worse than a calendar. +- **Duplication of meta-spec content**.

When a component is removed, delete its section. `git log` keeps the history. + +### Sanity-check checklist + +Before committing an arch.md change, run through these: + +1. Does the section describe **current state**, not aspiration? +2. Does it duplicate a meta-spec? If yes, replace with a summary + pointer. +3.

To roll back: `git revert` the phase-1 commit. No downstream consumers depend on these artifacts at this point in the merge order, so revert is safe. + +#### Risks + +- **Risk**: Skill description doesn't trigger reliably from natural-language invocations. + - **Mitigation**: Deterministic literal-content check guards what's *written*; manual smoke test in Phase 2 verifies behavior.

The matrix routes each fact/insight to a single canonical home.

(`git log` retains history.) | + + Eight rows total; the eighth (retired components) is added beyond the issue's starter list to address the "graveyard" pattern visible in the live `arch.md`. + +2. **Split Step 3 ("Sync Documentation") into 3a (Audit) and 3b (Update)**: + - **Step 3a — Audit documentation**: invoke the `update-arch-docs` skill in audit-mode. Produce a candidate-cuts list against the per-arch.md-section pruning checklist and per-lessons-learned.md-entry pruning checklist. Record findings in the run file (`codev/maintain/NNNN.md`) under a new `## Audit Findings` section before any edits land. + - **Step 3b — Update documentation**: apply the audit decisions plus any new content (the existing Step 3 work). Continue using the `update-arch-docs` skill in diff-mode for any specific changes. + - Step numbers 1, 2, and 4 keep their existing numbering. + +3. **Add the pruning checklists** as inline content under Step 3a: + - **For each arch.md section**: Does it describe current state? Does it duplicate a meta-spec? Is it a per-file enumeration that's gone stale? Is it a changelog/narrative section? + - **For each lessons-learned.md entry**: Is it cross-applicable beyond the spec that produced it? Is it terse (1-3 sentences)? Is the topic section the right one? Is it a duplicate of an adjacent entry? + +4. **Add a sample audit prompt** (a checklist invocation that asks the skill to identify sections to cut) as a code block under Step 3a. + +5. **Update the run-file format** (the `## What Was Done` template) to include a `## Audit Findings` section with the schema: + ``` + ## Audit Findings + ### arch.md + - : + ### lessons-learned.md + - : + ``` + +6. **Cross-reference the skill** from the protocol — Step 3a and Step 3b each call out `update-arch-docs` by name and link to `.claude/skills/update-arch-docs/SKILL.md`. + +**Verification battery** (run in this order, results recorded in `codev/reviews/723-improve-arch-md-lessons-learne.md`): + +1. Skeleton/main parity — `diff -r` across all touched pairs: + - `diff codev/templates/arch.md codev-skeleton/templates/arch.md` + - `diff codev/templates/lessons-learned.md codev-skeleton/templates/lessons-learned.md` + - `diff codev/protocols/maintain/protocol.md codev-skeleton/protocols/maintain/protocol.md` + - `diff -r .claude/skills/update-arch-docs/ codev-skeleton/.claude/skills/update-arch-docs/` +2. Skill literal-content check — verify required frontmatter phrases and body sections (re-run from Phase 1; defends against regressions). +3. Scaffold tests — `pnpm --filter @cluesmith/codev test -- scaffold` (positional argument; Vitest does not support `--testPathPatterns`). Run in background; reasonable timeout 120s. +4. `codev init` smoke test — explicit command sequence: + ```bash + pnpm --filter @cluesmith/codev build # Phase 2 must build first; dist/ is not present in worktree + mkdir -p /tmp/codev-723-smoke + node packages/codev/dist/cli.js init /tmp/codev-723-smoke + ``` + Then verify: + - `cat /tmp/codev-723-smoke/codev/resources/arch.md` — matches the new richer template (grep for the "Updating This Document" preface marker). + - `cat /tmp/codev-723-smoke/codev/resources/lessons-learned.md` — has the new preface (grep for "what NOT to add"). + - `ls /tmp/codev-723-smoke/.claude/skills/update-arch-docs/SKILL.md` — exists. + Then `rm -rf /tmp/codev-723-smoke`. + **Fallback if `pnpm build` fails or dist invocation breaks**: verify the skeleton template content directly: `cat codev-skeleton/templates/arch.md` and confirm the preface and section stubs are present. (The smoke test's purpose is to verify the templates are correct; reading the skeleton template directly demonstrates the same thing without exercising the propagation pipeline.) +5. Skill propagation via `codev update` — explicit command sequence: + ```bash + pnpm --filter @cluesmith/codev build # if not already built in step 4 + mkdir -p /tmp/codev-723-update + node packages/codev/dist/cli.js init /tmp/codev-723-update + rm -rf /tmp/codev-723-update/.claude/skills/update-arch-docs # simulate "existing project missing the new skill" + (cd /tmp/codev-723-update && node /Users/mwk/Development/cluesmith/codev/.builders/spir-723/packages/codev/dist/cli.js update) + ls /tmp/codev-723-update/.claude/skills/update-arch-docs/SKILL.md # should now exist again + rm -rf /tmp/codev-723-update + ``` +6. Self-consistency check — invoke `update-arch-docs` in audit-mode against `codev/resources/arch.md`. Capture at least three categories of candidate cuts in the review document. **Do not apply the cuts** — that's a separate MAINTAIN run, out of scope per the spec. +7. Manual smoke test of skill discovery — invoke `/update-arch-docs` and confirm it surfaces. Note the result in the review. + +**PR preparation**: + +- Branch: `builder/spir-723` (already in use; this is the existing builder worktree). +- PR title: `[Spec 723] Improve arch.md / lessons-learned.md governance`. +- PR description includes: + - Summary of all six issue scope items addressed. + - **Post-merge cutover (architect action required)**: `rm ~/.claude/agents/architecture-documenter.md` — surfaced prominently near the top of the description. + - List of files changed. + - Verification results (parity checks, test runs, self-consistency findings). + +#### Acceptance Criteria + +- [ ] Both MAINTAIN protocol files updated with all six edits (matrix, Step 3a/3b, two checklists, sample audit prompt, run-file format update, skill cross-reference). +- [ ] `diff` parity checks across all four touched pairs produce no output. +- [ ] Scaffold tests pass. +- [ ] `codev init` smoke test produces all expected artifacts. +- [ ] Self-consistency check found ≥3 candidate-cut categories — recorded in review doc. +- [ ] PR description drafted with the post-merge cutover note prominently surfaced. + +#### Test Plan + +- **Unit Tests**: `pnpm --filter @cluesmith/codev test -- scaffold`. +- **Integration Tests**: `codev init` smoke test (covered above). Skill propagation via `codev update` (covered above). +- **Manual Testing**: Skill discovery (manual `/update-arch-docs` invocation). Audit-mode self-consistency check against live arch.md. + +#### Rollback Strategy + +If MAINTAIN protocol edits cause confusion in the next maintenance run, `git revert` the Phase 2 commit. The Phase 1 artifacts (skill + templates) remain valid and useful even without the MAINTAIN integration — the protocol simply reverts to its previous "single Step 3" shape. + +#### Risks + +- **Risk**: Audit-mode self-consistency check fails to find ≥3 categories. + - **Mitigation**: The live `codev/resources/arch.md` is 1,812 lines and visibly contains per-spec changelog sections, exhaustive enumerations, and aspirational/retired components — three categories already verified to exist by manual inspection. If audit-mode somehow misses them, that's a skill prose bug we can fix by improving the audit-mode section text. +- **Risk**: Scaffold tests fail because `copyResourceTemplates` references a file that no longer exists. + - **Mitigation**: We are not removing any existing templates, only updating their content. The template list in scaffold.ts (`['lessons-learned.md', 'arch.md', 'cheatsheet.md', 'lifecycle.md']`) is unchanged. Cross-checked. +- **Risk**: `codev init` smoke test produces stale content because the binary in `packages/codev/dist/` predates Phase 1 changes. + - **Mitigation**: Phase 1 changes are template content, not packaged code. Templates are read from `codev-skeleton/` at runtime, not bundled into the binary. Verified by reading `packages/codev/src/lib/scaffold.ts` — it `path.join(skeletonDir, 'templates', template)`. + +--- + +## Dependency Map + +``` +Phase 1 ──→ Phase 2 +(skill + templates) (MAINTAIN wiring + verification + PR) +``` + +Phase 2 strictly depends on Phase 1 because Phase 2 references the skill by name in the protocol. + +## Resource Requirements + +### Development Resources + +- **Engineers**: One AI builder (this agent).

They resolve at runtime from the installed npm package via the unified file resolver.` This is a **deliberate design decision** of the codev framework — templates are framework-resolved, not project-copied — and would affect every framework template (protocols, roles, consult-types, cheatsheet, lifecycle), not just arch.md/lessons-learned.md, if changed. +- **Spec deviation noted**: the spec's success criterion #103 ("A scratch `codev init` (or equivalent) into a tmp directory produces the new richer arch.md ...") was based on an implementer misunderstanding of the framework's propagation model at spec time.

It introduced no new subsystems, no new data flows, no new architectural decisions, no new file locations within `packages/codev/`. The only source-level reference touched was reading `packages/codev/src/lib/scaffold.ts` to verify propagation semantics (`copyResourceTemplates` for templates, `copySkills` for skills) — and even that finding (templates are init-time only, skills propagate via `update`) is already documented inline in the new arch.md template's "Updating This Document" preface and in the spec's Resolved Decisions section. + +The new `update-arch-docs` skill is documented in this PR as a first-class artifact; if the live arch.md grew an "Available Skills" section in the future, that's where it would land — but the current arch.md does not maintain such a section, and adding one purely to mention the new skill would itself be the kind of add-bias the spec is fixing. + +## Lessons Learned Updates + +**No live `codev/resources/lessons-learned.md` updates in this PR.** + +The five candidate lessons listed below are recorded in this review document.

Architect feedback collapsed this to a clean replacement; the resulting design is simpler and avoids ambiguity. *General principle*: when introducing a new mechanism that supersedes an old one, prefer cutover over coexistence — coexistence framing accumulates ambiguity that compounds over time. + +- **Author governance discipline as prose, not as code.** The skill body is markdown prose codifying what NOT to do; it has no executable surface and no tests beyond literal-content checks. This is the right shape for governance: enforcement is by review, not by runtime. Trying to make it "executable" (e.g. a linter that flags per-spec changelog patterns) would be premature complexity. *General principle*: governance docs that exhort a discipline can ship as prose alongside the things they govern; the system that needs them is the human + LLM reviewing the PR. + +- **Plan checks should test the actual change surface, not the broader suite.** Initial plan said `pnpm --filter @cluesmith/codev test -- --testPathPatterns=scaffold` but Vitest doesn't accept that flag. After fix (`pnpm exec vitest run scaffold` — positional), the test ran cleanly in 141ms. Running the full suite would have surfaced unrelated pre-existing flaky session-manager tests and obscured the result. *General principle*: target verification at the change surface; broader suites mask signal with pre-existing noise. + +- **Two homes are simpler than three (architect intervention).** The original design had three places carrying the documenter discipline: the skill, a new `arch-md-guide.md` template, and the MAINTAIN protocol. Architect compressed to two: the skill (discipline content) and the arch.md preface (in-template reminder). Removing the third home cut redundancy without losing any load-bearing content. *General principle*: when discipline content has multiple homes, ask which homes are *load-bearing*; collapse the rest. + +- **Pre-existing scaffold behavior shapes the smoke-test scope.** The plan assumed `codev init` would copy resource templates; in fact `init.ts` only copies skills + root files (templates are scaffold-internal, used by `adopt` and tests but not `init`).

The MAINTAIN protocol now refers to the skill twice (Step 3a and Step 3b) using consistent naming and a relative path. +- **Concern (minor)**: Audit-mode prose should echo "when in doubt, KEEP" so audit isn't over-aggressive. + - **Addressed**: Added explicit instruction to the skill's `## Mode: audit-mode` section. + +### Implement Phase 1 (Round 1) + +#### Gemini (APPROVE) +- No concerns raised — Phase 1 deliverables "complete, exact, and correctly synchronized to the skeleton directory." + +#### Codex (REQUEST_CHANGES) +- **Concern**: Skill files still untracked (`??` in git status); Phase 1's keystone deliverable not actually landed. + - **Addressed**: Pure administrative concern — skill files were committed atomically in commit ca003d99 immediately after the consult ran. No content change needed. + +#### Claude (APPROVE) +- No concerns raised — detailed verification table confirmed all six deliverables correct, all parity checks pass, all literal-content checks pass.

State updates automatically when porch advances on `porch done`. + +#### Claude (APPROVE) +- No concerns raised. Detailed verification confirmed all six MAINTAIN edits in place; parity zero; "when in doubt, KEEP" preserved in three load-bearing locations; matrix rows match plan verbatim.

It biases the agent toward **adding** rather than **editing or removing**. The MAINTAIN protocol invokes "Update arch.md" as a single pass that is functionally equivalent to "add what's new". + +The lived consequence is visible in the repo today: `codev/resources/arch.md` is 1,812 lines and contains per-spec narrative ("Spec 0104"), changelog framing, and exhaustive file lists that go stale the moment they're written. `lessons-learned.md` mixes durable, cross-cutting wisdom with spec-narrow recipes. + +This spec groups several governance improvements that together shift the workflow from **"append by default"** to **"audit, then update."** + +## Current State + +**`architecture-documenter` agent**: +- Defined as a Claude Code agent at `~/.claude/agents/architecture-documenter.md` (user-global, not in repo). +- Invoked ad-hoc by AI assistants in conversation; not a first-class step in any protocol. +- Prompt emphasizes thoroughness ("Be Specific and Actionable", "Include exact file paths", "Document every utility function") with no counter-pressure to compress, prune, or remove. +- No discipline distinguishing system-shape facts (arch.md) from cross-cutting engineering wisdom (lessons-learned.md). + +**`codev-skeleton/templates/arch.md`** (template shipped to other projects): +- 56-line scaffold with section stubs. +- No preface explaining how to read or maintain the doc. +- No "what NOT to put in" guidance. +- No section on verified-wrong assumptions or "skip what doesn't apply" framing. + +**`codev/templates/arch.md`** (template inside this repo, identical to skeleton): +- Same 56-line stub.

Contains per-spec changelog sections, full directory enumerations, and several aspirational/retired component descriptions. +- Working evidence that the current governance produces unbounded growth. + +**`codev/resources/lessons-learned.md`** (the live lessons-learned.md): +- 371 lines. Mixes durable engineering patterns with spec-numbered narrative entries. + +## Desired State + +After this work: + +1. **The architecture-documenter is a skill**, invoked as a standard step by the MAINTAIN protocol (and available ad-hoc). Its prompt embodies discipline about **what NOT to include** and the **two-doc framing** (arch.md owns system-shape; lessons-learned.md owns durable engineering wisdom). The skill *may* directly edit `arch.md` and `lessons-learned.md` via normal file-edit tooling — that's the expected mode of operation, and the resulting diff is what the MAINTAIN PR review checks. What the skill must NOT do is invoke destructive shell commands (no `rm -rf`, no `git rm`, no destructive `sed` scripts). Audit-mode still surfaces what it proposes to remove (with reasons) so PR reviewers can see the rationale, not just the diff. + +2. **The shipped `codev/templates/arch.md`** (and the matching `codev-skeleton/templates/arch.md`) is a richer template with a preface, opinionated section stubs, and explicit "skip what doesn't apply" framing. The preface includes the short "how to keep arch.md healthy" guide (when/how to update, what NOT to put in, sanity-check checklist) so the doc teaches its own maintenance norms inline. New projects start with a doc that already documents its discipline. + +3. **The shipped `codev/templates/lessons-learned.md`** (and matching skeleton copy) gains a preface mirroring arch.md's: how to read, when to add, what NOT to add (spec-narrow recipes, multi-paragraph entries, duplicate adjacent entries), and a sanity-check checklist. Currently the template is 28 lines of empty section stubs; the new version teaches its own pruning norms. + +4. **The MAINTAIN protocol** carries a **"Lives where"** matrix that routes each fact/insight to the right home, plus a **two-phase audit-then-update** flow with concrete pruning checklists. The audit-pass results are recorded in the run file (`codev/maintain/NNNN.md`) so reviewers can see *why* sections were targeted, not just the deletion diffs. + +5. **Both `codev-skeleton/` (template-for-others) and `codev/` (self-hosted)** carry the changes. Other projects pulling Codev get the upgraded governance; this repo also benefits from it. + +The deliverables are governance-doc edits — they do not change live `arch.md` / `lessons-learned.md` content directly. Cleanup of the existing 1,812-line `arch.md` is a separate MAINTAIN run that *uses* the new governance once it lands. + +## Stakeholders + +- **Primary Users**: AI builders and architects (Claude Code, Cursor, Copilot users) running MAINTAIN or invoking architecture documentation work. +- **Secondary Users**: Human maintainers of Codev-using projects who read these files. +- **Technical Team**: This builder (project 723) implements; architect approves; users of `codev-skeleton/` inherit on next `codev update`. +- **Decision Authority**: Codev project owner (architect). + +## Success Criteria + +### Skill (deterministic checks) + +- [ ] A skill named `update-arch-docs` (chosen to avoid collision with the user-global `architecture-documenter` agent — see Resolved Decisions) exists at `.claude/skills/update-arch-docs/SKILL.md` in this repo and at `codev-skeleton/.claude/skills/update-arch-docs/SKILL.md` in the skeleton. Both `SKILL.md` files are byte-identical. +- [ ] The skill's frontmatter `description` field includes all of: the phrases "arch.md", "lessons-learned.md", and "MAINTAIN", plus an explicit trigger sentence ("Use this skill when running MAINTAIN's arch-doc step, or when asked to update / audit / prune `codev/resources/arch.md` or `codev/resources/lessons-learned.md`."). This is a literal-content check, not a behavioral one. +- [ ] The skill body contains, as named sections: `## What this skill does NOT do`, `## arch.md vs. lessons-learned.md (two-doc framing)`, `## Sizing by purpose, not by line count`, `## Mode: diff-mode (apply a specific change)`, `## Mode: audit-mode (identify what to cut)`, and `## Output contract` (which states: the skill edits arch.md / lessons-learned.md directly via normal file-edit tooling and does not invoke destructive shell commands; in audit-mode it surfaces the *reasons* for proposed removals alongside the diff so PR reviewers can evaluate intent, not just outcome). +- [ ] Manual smoke test: running `/update-arch-docs` (or natural-language paraphrase) from inside this repo loads the skill. Result is recorded in the review. + +### Templates + +- [ ] `codev/templates/arch.md` and `codev-skeleton/templates/arch.md` are replaced with a richer template that includes (a) the opinionated section stubs listed in the issue (TL;DR, Repository Layout & Stack, per-subsystem mechanism, Apps Roster, Packages Roster, Verified-Wrong Assumptions, Updating This Document), (b) "skip what doesn't apply" framing, and (c) an inline preface — under the "Updating This Document" section — covering when to update, how to update, what NOT to put in, and a sanity-check checklist. The preface notes that `codev update` does not propagate templates, so existing projects must opt in by manual copy. Both files are byte-identical. +- [ ] `codev/templates/lessons-learned.md` and `codev-skeleton/templates/lessons-learned.md` are updated with a preface and "what NOT to add" guidance (no spec-narrow recipes, no multi-paragraph entries, no duplicate adjacent entries) plus a sanity-check checklist. Both files are byte-identical. + +### MAINTAIN protocol + +- [ ] `codev/protocols/maintain/protocol.md` and `codev-skeleton/protocols/maintain/protocol.md` are byte-identical and carry: the "Lives where" matrix, an audit-pass split inside Step 3 (renamed to Step 3a "Audit documentation" and Step 3b "Update documentation"), a sample audit prompt, per-arch.md-section pruning checklist, per-lessons-learned.md-entry pruning checklist, and an explicit instruction to record audit findings in the run file (`codev/maintain/NNNN.md`). +- [ ] The new Step 3a / Step 3b structure preserves the existing Step 1, Step 2, Step 4 numbering so in-flight runs are not disrupted; this is a sub-step split, not a renumber of the parent steps. + +### Whole-spec checks + +- [ ] No live `arch.md` / `lessons-learned.md` content is rewritten as part of this spec — that work belongs to a future MAINTAIN run. +- [ ] A self-consistency check: applying the new audit-mode skill to the existing 1,812-line `codev/resources/arch.md` produces at least 3 distinct categories of candidate cuts (e.g., per-spec changelog, exhaustive enumerations, aspirational sections). Findings are summarized in the review document — no actual cuts made. +- [ ] `diff -r` parity verification across all touched skeleton/codev pairs (templates, protocol, skill) produces no output. +- [ ] Tests touching the affected scaffold logic still pass: `pnpm --filter @cluesmith/codev test -- --testPathPatterns=scaffold` (narrower than full `pnpm test`, targets the actual change surface). +- [ ] A scratch `codev init` (or equivalent) into a tmp directory produces the new richer arch.md (with inline preface), the new lessons-learned.md preface, and (in the project's `.claude/skills/`) the `update-arch-docs` skill. + +## Constraints + +### Technical Constraints + +- **Skill format compliance**: The new skill must conform to Claude Code's skill format (frontmatter with `name` and `description`; SKILL.md as the entry point; located under `.claude/skills//SKILL.md`). +- **No destructive shell commands in the skill**: SKILL.md must not include `rm -rf`, `git rm`, or destructive `sed` scripts. The skill *may* directly edit `arch.md` and `lessons-learned.md` via normal file-edit tooling — those edits land in the MAINTAIN PR diff and get reviewed there. In audit-mode the skill surfaces reasons alongside the diff (e.g. "removing this section because it's a per-spec changelog — see arch.md preface §3"). PR review is the human-confirmation step; no separate gate. +- **Skeleton/main parity (why we keep them byte-identical)**: This repo has a dual nature. `codev/` is the self-hosted instance — the version *we* use. `codev-skeleton/` is what gets copied to other projects on `codev init` / `codev adopt` (and, for `.claude/skills/`, on `codev update`). When the same artifact exists in both directories — templates, protocols, skills — it must stay byte-identical so **what we ship is what we use**, and so we don't repeat the drift that has bitten prior work. `diff -r` verification across the touched pairs is a Success Criterion above. +- **Step 3 sub-step split, not renumber**: Existing maintenance runs should still complete. The audit-pass is a sub-step split inside Step 3 ("Sync Documentation") into Step 3a (Audit) and Step 3b (Update). Steps 1, 2, and 4 keep their numbering. This preserves the existing top-level structure for tools/runners that key off it. +- **Cutover from the user-global agent**: The `update-arch-docs` skill *replaces* the `architecture-documenter` agent at `~/.claude/agents/architecture-documenter.md`; it does not run alongside it. That file lives outside this repo, so the PR cannot delete it directly. The PR description must call out the cutover explicitly so the architect can `rm ~/.claude/agents/architecture-documenter.md` as part of merge. + +### Business Constraints + +- **Scope-bounded**: This spec implements exactly the six items listed in issue #723. Anything in the "Out of Scope" section is deferred to follow-up issues. +- **No live-doc rewrites in this spec**: The rewrite of `codev/resources/arch.md` itself is explicitly out of scope. This spec only ships governance. + +## Assumptions + +- The Claude Code skill format and discovery mechanism (the `.claude/skills/` directory, SKILL.md frontmatter) is stable and available to the audience consuming Codev. +- MAINTAIN consumers run their AI assistant inside the project worktree, which gives skills the chance to surface. +- Existing skills in this repo (`afx`, `consult`, `porch`, `codev`, `forge`, `team`, `skill-creator`, `generate-image`) are working examples of the format we should follow. +- The architect will not block on the "self-consistency check" success criterion — it is a smoke test, not a deliverable. + +## Solution Approaches + +### Approach 1: Skill + template replacement + MAINTAIN protocol edits (chosen) + +**Description**: Implement all six items as a coordinated set of edits. The skill is the new home for the documenter's discipline; the template replacement is a one-time content swap; the MAINTAIN protocol gets new sub-sections (matrix, audit pass, checklists). Apply each change in both `codev/` and `codev-skeleton/` so both internal and downstream users benefit. + +**Pros**: +- Faithful to the issue's six-item scope. +- Each change is a small, reviewable diff. +- Composes well: the new skill reads naturally when invoked from the MAINTAIN protocol's audit-pass step. +- Leaves the live arch.md untouched, so reviewers can validate the governance without drowning in 1,800-line cleanup diffs. + +**Cons**: +- Six edits across multiple files create some review surface. +- The skill duplicates concerns also articulated in the MAINTAIN protocol; we have to be careful not to write the same guidance twice in different voices. + +**Estimated Complexity**: Medium +**Risk Level**: Low (no executable code; all changes are docs/skill content) + +### Approach 2: Single combined "doc-governance.md" file + +**Description**: Collapse the skill, the new arch-md-guide, and the new MAINTAIN sub-sections into one canonical governance file that all the others link to. + +**Pros**: +- One source of truth. +- No duplication. + +**Cons**: +- Skills must self-contain their triggering content (frontmatter + body) to be discoverable. A skill that only `cat`s another file gives a worse triggering experience. +- The MAINTAIN protocol benefits from inlining the matrix and checklists where they're used; pointer-only is harder to follow during execution. +- Diverges from how other Codev skills are structured (each is a self-contained directory). + +**Decision**: Reject. The duplication concern is real but mitigated by careful authoring; the discoverability and locality wins of Approach 1 outweigh the DRY win. + +### Approach 3: Defer the skill conversion; only ship template + MAINTAIN edits + +**Description**: Leave `architecture-documenter` as a user-global agent for now; ship the richer template, the guide, and the MAINTAIN updates. + +**Pros**: +- Smaller diff. Faster ship. + +**Cons**: +- The issue explicitly identifies the skill conversion as the natural place to bake in pruning discipline. Skipping it leaves the agent's prompt as the dominant influence on documenter behavior, undercutting the MAINTAIN-side improvements. +- Leaves a known gap that will need a follow-up. + +**Decision**: Reject. The skill is the keystone. + +## Resolved Decisions + +These were open questions in the initial draft. Resolved during 3-way consultation: + +- **Skill name**: `update-arch-docs`. Architect-mandated: name describes what the skill does, not who it is. Action-oriented and distinguishable from the legacy `architecture-documenter` agent that this skill replaces. +- **Skill replaces, does not coexist with, the legacy agent**: `~/.claude/agents/architecture-documenter.md` is being retired. Architect deletes it as part of merge (PR description calls this out — the file path is outside the repo, so the PR cannot delete it directly). +- **Skeleton skill location**: `codev-skeleton/.claude/skills/update-arch-docs/SKILL.md`. The skeleton does have a `.claude/skills/` directory (verified: contains `afx`, `codev`, `consult`, `generate-image`, `porch`). New skills propagate to existing downstream projects via `codev update` (calls `copySkills` with `skipExisting: true`). +- **Diff-mode vs audit-mode**: Both are behaviors selected from invocation phrasing, with each getting its own named section in the skill body. Both modes can directly edit `arch.md` and `lessons-learned.md`; audit-mode additionally surfaces *reasons* alongside the diff so PR reviewers can evaluate intent. +- **No separate arch-md-guide.md**: The maintenance guide for arch.md ships as a preface inside the new arch.md template (under "Updating This Document") and as the discipline content of the `update-arch-docs` skill. Two homes, both load-bearing — not three. +- **Step 3 restructuring**: Sub-step split into 3a (Audit) and 3b (Update). Top-level step numbers 1, 2, 4 are unchanged. +- **Template propagation**: `codev update` does NOT copy templates — only `init`/`adopt` does. The new richer arch.md template only lands in *new* projects. Existing projects need to manually copy if they want the new template; this is documented in the arch.md template's preface so users aren't surprised. + +## Open Questions + +### Important (Affects Design) + +- [ ] **"Lives where" matrix exact rows**: The issue offers a starter matrix; final rows to be locked down during the plan phase. Builder will propose, architect approves at plan-approval gate. + +### Nice-to-Know (Optimization) + +- [ ] **Self-consistency check scope**: How thorough should the smoke-test against the existing 1,812-line arch.md be? Default: 3–5 illustrative findings recorded in the review document, not a comprehensive audit. + +## Test Scenarios + +### Functional Tests + +1. **Skill literal-content check**: `cat .claude/skills/update-arch-docs/SKILL.md` and confirm: the frontmatter `description` contains the required phrases ("arch.md", "lessons-learned.md", "MAINTAIN", trigger sentence) and the body contains the required named sections (`## What this skill does NOT do`, `## arch.md vs. lessons-learned.md (two-doc framing)`, `## Sizing by purpose, not by line count`, `## Mode: diff-mode (apply a specific change)`, `## Mode: audit-mode (identify what to cut)`, `## Output contract`). +2. **Skill discovery (manual)**: With Claude Code running in this repo, type `/update-arch-docs` and confirm the skill loads. Result is recorded in the review document. (Behavioral; verified manually, not as a deterministic acceptance criterion.) +3. **Skill propagation via update**: In a scratch sandbox project that has Codev installed (without the new skill), run `codev update` and verify `.claude/skills/update-arch-docs/SKILL.md` is now present. +4. **Template smoke-test**: Run `codev init scratch-project` in a tmp directory; verify `codev/resources/arch.md` matches the new richer template (including the inline "Updating This Document" preface) and `codev/resources/lessons-learned.md` matches the new template. +5. **MAINTAIN audit-pass dry-run**: Walk through Step 3 (now 3a + 3b) of the updated MAINTAIN protocol against `codev/resources/arch.md`. Verify Step 3a produces a reviewable list of "sections to cut" before Step 3b runs, and that the run file format includes a section for audit findings. +6. **Skeleton/main parity**: `diff -r codev/templates/ codev-skeleton/templates/` produces no output for the touched files. Same parity check for `protocols/maintain/protocol.md` and the new skill directory. +7. **Targeted test run**: `pnpm --filter @cluesmith/codev test -- --testPathPatterns=scaffold` passes. +8. **Self-consistency check**: Use audit-mode against `codev/resources/arch.md`. Record at least 3 categories of candidate cuts in the review document. (Smoke test only; cuts are NOT applied.) + +### Non-Functional Tests + +1. **Template readability**: A human reader unfamiliar with Codev should be able to skim the new arch.md template (including the inline "Updating This Document" preface) and answer "what goes here? what does NOT go here?" in under 2 minutes. +2. **Skill triggering quality (informational)**: The skill's `description` is specific enough that Claude doesn't surface it on unrelated work but does surface it for "update the architecture doc" / "what should I prune from arch.md" / MAINTAIN protocol contexts. This is informational because triggering depends on the LLM; the deterministic checks above guard the literal content. + +## Dependencies + +- **External Services**: None. +- **Internal Systems**: + - Claude Code skill format (consumed) + - MAINTAIN protocol (modified) + - `codev update` mechanism for propagating skeleton changes (relied on, not modified) +- **Libraries/Frameworks**: None. + +## References + +- GitHub Issue: #723 — Improve arch.md / lessons-learned.md governance +- Legacy agent prompt being retired: `~/.claude/agents/architecture-documenter.md` (user-global; deleted by architect at merge time) +- Existing MAINTAIN protocol: `codev/protocols/maintain/protocol.md` +- Existing arch.md template: `codev/templates/arch.md`, `codev-skeleton/templates/arch.md` +- Existing skills in repo: `.claude/skills/{afx,codev,consult,forge,porch,team,skill-creator,generate-image}/` +- Scaffold logic: `packages/codev/src/lib/scaffold.ts` (templates copied via `copyResourceTemplates`; skills via `copySkills`) +- Live arch.md (target of governance, not edited here): `codev/resources/arch.md` +- Live lessons-learned.md (target of governance, not edited here): `codev/resources/lessons-learned.md` + +## Risks and Mitigation + +| Risk | Probability | Impact | Mitigation Strategy | +|------|------------|--------|-------------------| +| Skill format changes underneath us | Low | Medium | Pin to current frontmatter shape; verify against existing skills before shipping. | +| Skeleton-vs-codev drift introduced by this spec | Medium | Medium | `diff -r` parity check is a success criterion; verified before PR. | +| Skill duplicates MAINTAIN protocol content verbatim | Medium | Low | Skill owns discipline (what NOT to include, two-doc framing); MAINTAIN owns flow (audit then update).

Two homes, both load-bearing — not three. +- **Relaxed "guidance-only" constraint** to "no destructive shell commands"; clarified that direct file edits to arch.md / lessons-learned.md are expected and reviewed in the MAINTAIN PR diff. +- **Reworded skeleton/main parity constraint** to explain *why* (codev/ is what we use; codev-skeleton/ is what we ship; byte-identical files prevent drift). +- **Removed coexistence framing** for the legacy user-global agent. The skill *replaces* the agent. Added post-merge cutover note ("rm ~/.claude/agents/architecture-documenter.md") to the spec and to PR description requirements.
