Defame1297 311e7cd22c fix(kyberforge): reconcile the authoring rules the ADR-0020 trim left disagreeing
Six defects, each one a place where two files that an author reads in the same
sitting told them different things — or where the trim dropped a rule and nothing
noticed because no gate covers prose.

**"Use proactively" contradicted itself across the pair.** All three agent
templates said to add it where the runtime should delegate unprompted, while
`agent-audit`'s `KyberforgeCopilot.ProactivePhrase` rule grades it a hard FAIL in
any `*.agent.md` — which is the Copilot half of every project/user pair *and* the
vendor-neutral plugin-scope file, since that compiles to a real Copilot agent
downstream. Following the template produced a file the repo's own gate rejects.
The phrase is now permitted in exactly one place, the Claude Code `.md`, and
`references/contract.md` carries the per-file table plus the consequence authors
ask about next: a pair whose CC half has it and whose Copilot half does not is
correct, because `agent-audit` checks that both halves describe the same job, not
that they match word for word.

**The output-schema rule contradicted itself inside one file.** `contract.md`
said any content only one branch reaches moves to `references/`, and then offered
an "Output format template" body pattern with no qualification. Stated once now,
so it is not re-litigated: an output schema stays in the body only when every flow
produces it and it is roughly 50 words or less. No third option.

**Gotchas tiers disagreed with the script.** `validate.sh` emits the entry count
through `suggest()` and exits 0, while `skill-author` and `skill-audit` both
called more than five entries a FAIL. Whether a given gotcha earns its place is
judgment, so the prose moves to the script's tier rather than the reverse. The
paraphrase rule stays a FAIL and is explicitly marked as the auditor's call — no
script detects it.

**The dispatch exemplar was cited at the wrong number.** `apm-workflow`'s body is
421 words; 554 is its whole-file count. Both `contract.md` and `body-discipline.md`
cited 554 while describing a body budget, so an author calibrating against the
exemplar overshot by ~30% — the exact whole-file/body-only conflation those two
sections exist to warn against, reproduced inside the warning.

**"Error handling" came back as a required body element.** It was one of four and
is the one that gets dropped, and dropping it is not neutral: an agent handed
malformed input with no instruction invents a recovery, and a subagent's invented
recovery is invisible to its caller until the output is wrong. Restored in
`agent-audit`'s rubric as a SUGGESTION, in `agent-author`'s contract and both
scope checklists as a required element, and as an `## Errors` section in all three
templates.

**`skill-author` Step 4 gains the one check the audit misses.** An empty body
reports `PASS SKILL.md body word count 0` — a word gate cannot tell "concise"
from "absent". Step 4 now hand-checks for a non-empty section, and its commit
verification is conditioned on actually being inside a git worktree, which a skill
under `~/.claude/skills/` is not.

Also here: absolute repo paths removed from `skill-author`'s SKILL.md and
contract.md in favour of naming the skill (`zoom-out`'s description is quoted
inline instead of pointed at), the boundary-target universe documented to match
the resolver, a two-hops-from-SKILL.md limit on reference chains, and
`new-agent.sh`'s next-steps output naming the description budget and the
deliberate absence of an agent body gate.

Gotchas

  • The word gates are two measurements, not two tiers of one rule: the 2,770-word / 500-line spec backstop counts the whole file, Step 3's gate the body alone. Never unify them.
  • Never spawn a subagent to audit or recheck your own work — run /skill-audit inline, in the same context as the edits. Clean-context recheck belongs to /forge's outer loop, and a self-spawned subagent's worktree can be torn down by concurrent cleanup, destroying an uncommitted draft.
  • Do not create new scripts unless a signal explicitly calls for it. Writing one from scratch requires out-of-scope transcript analysis — flag the opportunity as a suggestion instead.

Step 1 — Dispatch

Condition Flow Reference
No skill directory at the target path Create references/create.md
Directory exists, at least one improvement signal present Improve references/improve.md
Directory exists, no signals Stop and ask —

Signals: grill output, /skill-audit findings, inline feedback, eval results, session context describing what went wrong. With none, ask whether the user meant to create a new skill or has feedback to apply.

Read only the reference matching the resolved flow — each is self-contained. If the target sits inside a git worktree, capture git log --oneline -1 before touching the filesystem; Step 4 needs it.

Step 2 — Invocation axis

Decide before writing any description: model-invoked or hand-invoked?

  • Hand-invoked — the user types /name and no agent should route to it. Set disable-model-invocation: true and write one plain human-facing sentence: no trigger list, no boundary clause. Skip Step 3's description rules.
  • Model-invoked — the default.

Step 3 — Contract

Before writing or editing a description, or restructuring a body, read references/contract.md — the banned-content list, boundary form, include/exclude rubric and body patterns.

Gates /skill-audit enforces in both flows:

  • Description — a trigger clause, at most one capability clause, and a boundary clause shaped Not <thing> -> <skill-name> whose target resolves to a real skill or agent. 250 characters SUGGESTION, 400 FAIL, value only.
  • Body — decision procedure only: ordered steps, branches, gates, and which reference to load when. 600 words SUGGESTION, 900 FAIL, body only. At two or more mutually exclusive flows a dispatch table is mandatory and each flow gets its own self-contained references/ file.
  • Gotchas — each contradicting a reasonable default. A Gotcha paraphrasing a step below it is a FAIL; over five entries is a SUGGESTION only.

Step 4 — Validate and close

Run /skill-audit on the resolved skill directory; resolve every FAIL before reporting done. It checks name-to-directory match, placeholders, both size budgets, boundary-target resolution and script hygiene — do not hand-check those. Hand-check the one thing it misses: an empty body reports PASS SKILL.md body word count 0 (ADR-0020 target: 600), so confirm at least one non-empty section exists.

With metadata.version present, bump the minor version on create (new skills start at 0.1.0) and the patch version on improve.

Commit verification. Inside a git worktree: once the audit is clean, run git add and git commit — do not stop at staging. Re-run git log --oneline -1 and confirm the hash changed from Step 1's. A non-empty git diff --stat is not proof: staged-but-uncommitted work is part of no commit and is silently lost if the tree is cleaned up. Report done only once the hash has changed. Outside a worktree (a skill under ~/.claude/skills/, say) nothing is committable — report done on a clean audit, naming that as the reason.
