/ad-archive
Removes plan files whose decision-record lifecycle is over. Git history retains the content; the working tree stops paying context cost on artifacts the LLM no longer needs to scan.
Rationale
Decision-record artifacts (doc/adr/, doc/tasks/, doc/specs/, doc/product/) carry their lifecycle in a Status: frontmatter field. Once an item reaches a terminal state (task done, spec shipped, PRD superseded, ADR superseded / deprecated), keeping the file in the working tree adds tokens every time an agent globs the directory but adds zero binding force — the work has shipped, the decision has been replaced, or the rationale has been absorbed into a permanent doc.
/ad-archive removes them via git rm. Three rules anchor the design:
- No
CHANGELOG.md, no archive/ subdirectory. WORKFLOW.md Rule #2 forbids changelogs in narrative documents; an archive/ subdir still expands under directory globs and defeats the point. Git history is the ledger; /ad-commit after /ad-archive is the breadcrumb. git log --diff-filter=D -- doc/adr/ reaches it when needed.
- Status-driven, not age-driven. A done task removed two days after completion is fine. An accepted ADR untouched for two years is not a candidate — accepted means binding.
- Accepted ADRs require absorption proof. Nygard's tradition treats accepted ADRs as immutable. The kit's lean-tree value justifies removal only when the ADR's substance — not just its slug citation — has been moved into a binding document such that deletion loses no information. The skill enforces this by grepping the named target for the ADR's core claim before allowing
git rm.
Step 1 — Discover candidates
Read frontmatter only; do not load full bodies. Build four candidate sets.
Tasks (doc/tasks/NNNN-*.md): include if Status: done. Exclude proposed, in-progress, blocked.
Specs (doc/specs/NNNN-*.md): include if Status: shipped. Exclude draft, accepted, anything superseded by SPEC-NNNN (the supersession chain is information; chain target stays).
PRDs (doc/product/PRD.md single-product or doc/product/<slug>.md multi-product): include if Status: superseded. Exclude draft, accepted.
ADRs (doc/adr/NNNN-*.md):
- Auto-include if
Status: superseded by ADR-NNNN or Status: deprecated. The supersession chain target stays.
- Do not auto-include
Status: accepted. Accepted ADRs require the explicit Step 3 absorption check below.
Legacy plan docs (prose files under doc/ that are not in adr/, tasks/, specs/, product/; e.g. doc/v0.2-cli-plan.md): present as candidates only when the user explicitly names them. Do not auto-include — these have no Status: field, so judgement is required.
Step 2 — Present the slate
Render one block per category with one line per candidate. Format:
### Tasks (done) — 3 candidates
- doc/tasks/0001-dogfood-agents-md.md done 2026-05-08 "Apply kit to itself..."
- doc/tasks/0002-foundation-and-bootstrap.md done 2026-05-08 "Foundation + bootstrap skill"
- doc/tasks/0029-skill-summary-frontmatter.md done 2026-05-10 "Move skill descriptions into per-skill frontmatter"
### Specs (shipped) — 0 candidates
(none)
### PRDs (superseded) — 0 candidates
(none)
### ADRs (superseded / deprecated) — 2 candidates
- doc/adr/0019-domain-language-layer.md superseded by ADR-0027 2026-05-10
- doc/adr/0024-failed-pattern.md deprecated 2026-05-11
Print a one-line summary tail: Total: N candidates across M categories. Hard-delete via git rm; git history retains. No CHANGELOG or archive subdir.
If a category has zero candidates, render the heading and (none) — do not skip silently.
If the user named legacy plan docs, render them under their own ### Legacy plan docs (user-named) — N candidates block.
Step 3 — Confirm + accepted-ADR absorption gate
Ask the user which categories to sweep. Default phrasing:
Proceed with all auto-included candidates? Or name a subset (e.g. "tasks only", "tasks + specs", "skip ADR-0019").
If the user wants to also remove one or more Status: accepted ADRs, run the absorption check before adding them to the removal set:
For each named accepted ADR:
- Ask the user where the decision has been absorbed. Required form:
<file>#<section-or-anchor> or <file>:<line> (e.g. ARCHITECTURE.md#data-flow, GUIDELINES.md§Naming, src/lib/profiles.js:23).
- Extract two-to-four substance keywords from the ADR's title and Decision section (not the slug — substance). Example: ADR-0004 "File-based task tracking" → keywords
file-based, task tracking, doc/tasks, Markdown.
- Grep the absorption target for each keyword. Require at least one keyword to match. (Title-derived literal keywords may collide; substance keywords are the test.)
- If the grep fails: refuse removal. Print:
ADR-NNNN absorption not verified. Substance keyword <X> not found in <target>. Absorb the rationale first (edit the binding doc), then re-run /ad-archive and re-name this ADR.
- If the grep succeeds: add to the removal set, print the matched location as evidence.
Do not silently downgrade the check. The absorption rule is the design's load-bearing constraint — it is the reason hard-delete is safe.
Step 4 — Execute
Single git rm invocation for all confirmed files (one shell call, atomic stage):
git rm doc/tasks/0001-...md doc/tasks/0002-...md doc/adr/0019-...md
Then run git status --short and print the staged deletions. Do not commit. Do not push. The user runs /ad-commit next to author the message and sign the DCO.
If git rm fails on any file (e.g. uncommitted local edits), abort the entire batch, print the error verbatim, and instruct the user to resolve the conflict before re-running.
Step 5 — Hand off
Print exactly:
N file(s) staged for deletion. Git history retains content.
Discoverability: `git log --diff-filter=D --name-only -- doc/`
Next: /ad-commit
Suggested subject: `docs: archive <N> implemented <kind(s)>`
Suggested body: list removed slugs and the binding doc(s) the substance was absorbed into (for accepted-ADR removals).
Output contract
Writes nothing to disk other than git rm staging. Never auto-commits. Refuses to remove Status: proposed | in-progress | blocked | draft | accepted artifacts except when the user explicitly names an accepted ADR and the absorption check passes. Refuses to create CHANGELOG.md or doc/<kind>/archive/ subdirectories — both violate kit discipline (Rule #2 and the lean-tree value respectively).
Next
/ad-commit — author the deletion commit (Conventional Commits + DCO sign-off)./ad-next — re-run the state survey; removed artifacts disappear from Layer 4 / Layer 5 counts./ad-audit — confirm no narrative document still cites the removed ADRs by slug as load-bearing context (decoration-citation rule per ADR-0030 §11).
