feat(doc-standards): documentation tiers, budgets, and the ceiling gate

Standing docs accrete a paragraph per PR with nothing pushing back; the
root AGENTS.md reached 8,130 words in 50 commits with the same rule
stated two and three times. This encodes the counter-pressure:

- docs/AGENTS.md becomes the documentation standard: the tier taxonomy
  (one home per fact), target word budgets, and the slop checklist.
- verify-doc-budgets joins doc-sync: word ceilings for the six
  accretion-prone standing docs, manifest-driven, frozen at current
  sizes and ratcheted down as each doc is brought to target.
- .agents/skills/dsh-doc-standards: the thin placement/audit/red-gate
  workflow over the standard, mirroring the dsh-translate-docs split.
- RFC (implemented/process) records the decision, alternatives, and
  the first audit cycle's deferred work list.

The gate's first catch was the standard itself (1,057 > 1,000); it
ships condensed to 984 words rather than with a raised ceiling.

description: 'Use when writing, moving, reviewing, or auditing documentation in the deepseek-harness repo — choosing where content belongs, trimming doc slop, responding to a verify-doc-budgets gate failure, or requests like "improve the docs", "audit the docs for slop", "where should this be documented", "this doc is too long".'

# Applying the DeepSeek Harness Documentation Standard
The contract lives in [docs/AGENTS.md](../../../docs/AGENTS.md) — the tier taxonomy, the word budgets, and the slop checklist. This skill is the workflow for applying it: placing content, auditing the corpus, and handling a red budget gate. It is guidance, not a script; keep judgment active and prefer a few well-proven fixes over a mass rewording pass.
## Sources of truth (read, don't re-summarize)
- [docs/AGENTS.md](../../../docs/AGENTS.md) — the taxonomy ("one home per fact"), budgets, slop checklist.
- [docs/rfc/README.md](../../../docs/rfc/README.md) — when a decision earns an RFC and how to file it; [docs/postmortem/README.md](../../../docs/postmortem/README.md) — when an incident earns a postmortem.
- [docs/i18n/README.md](../../../docs/i18n/README.md) — the bilingual pairing contract; editing either side of a pair obligates the counterpart in the same change.
- Root [AGENTS.md](../../../AGENTS.md) — the standing orders whose budget discipline this skill protects.
## Placing content
Run the placement test in the standard's taxonomy table, then check the constraints that make a placement expensive or wrong:
- Paired docs (`pnpm run verify-translation-pairing --list`) cost a zh counterpart update and a `--write` re-record on every edit — prefer an unpaired home for content that will churn.
- Generated catalogs are never hand-edited; if the fact belongs there, change the generator's source.
- Before renaming or moving any doc, grep for inbound references: `verify-md-links` catches Markdown links, `verify-doc-refs` catches `docs/*.md` citations in TypeScript comments, but nothing catches heading-anchor fragments — grep `#the-heading` across the repo yourself (one anchor is hardcoded in `scripts/gen-cordis-catalog.ts`).
- A move is atomic: remove from the old home, add to the new home, and fix every inbound link in the same change.
## Auditing the corpus
The audit is a hunt for the standard's slop checklist, cheapest probes first:
1. Measure: `pnpm run verify-doc-budgets --list`, then `git ls-files '*.md' | grep -v '^vendor/' | xargs wc -w | sort -rn | head -30` to spot unbudgeted outliers.
2. Hunt narrated history: `rg -n -g '!vendor' -t md "no longer|used to|previously|was moved|renamed"` — judge each hit; some are legitimate (quoting a contrast against a live alternative), most are drift.
3. Hunt duplication: take each standing-doc rule, grep one distinctive phrase from it across all Markdown; more than one home means all but one become links.
4. Hunt catalog restatement: compare README event/tool tables against the generated catalogs and JSDoc; hand copies get replaced by links.
5. Hunt spec-speak in `implemented/` RFCs: migration plans, test checklists, future-tense "should" — an implemented RFC describes what is.
6. Classify each finding: a mechanical trim lands as a small PR; a restructure or removal that changes what a doc promises gets a proposed RFC first (follow [dsh-find-simplifications](../dsh-find-simplifications/SKILL.md) for the RFC shape).
Compression discipline: every load-bearing rule survives — as one to three lines plus a link to the home that carries its why. Cut stories, duplicates, and status annotations; never silently drop a rule. If a cut rule has no durable home to link, create it (usually an RFC or postmortem) in the same change.
## When verify-doc-budgets goes red
1. Relocate: does the new content belong in a linked home (RFC, postmortem, cookbook, README) with a one-line pointer left behind?
2. Condense: can existing prose in the doc pay for the addition — a story compressed to its rule, a duplicate converted to a link?
3. Only then raise the ceiling: edit `scripts/doc-budgets.manifest.json` and justify the raise explicitly in the PR description. After any rewrite that shrinks a budgeted doc, ratchet its ceiling down to the new size plus modest headroom in the same PR.
## Validation and PR hygiene
For docs-only changes run at least `pnpm run doc-sync`, `pnpm run lint`, and `git diff --check`; if a paired doc was touched, update the counterpart (see [dsh-translate-docs](../dsh-translate-docs/SKILL.md)) and re-record with `pnpm run verify-translation-pairing --write`. Open a draft PR while the audit is still expanding; in the PR body, list what was trimmed/moved with word deltas, what was deliberately kept long and why, and which checks ran. The first audit cycle's deferred work list lives in [the doc-tiers-and-budgets RFC](../../../docs/rfc/implemented/process/2026-07-04-doc-tiers-and-budgets.md) § Deferred work.
