Claude Code AI - Gitea MCP 598a7c326a refactor(skills): retrofit the corpus to the ADR-0020 context contract (#129)
Retrofits all 39 skills to ADR-0020's description/body context contract, then fixes what six rounds of independent review found in that retrofit — including four ways the hot gate itself failed open.

Closes #99, #107, #108, #110, #111, #114, #115, #120.

## The retrofit (waves 1-5)

| | Start | Now |
|---|---|---|
| Description FAILs (>400 chars) | 26 | **0** |
| Body FAILs (>900 words, body-only) | 9 | **0** |
| Dangling routing targets | 2 | **0** |
| `Kyberforge.CompositionNote` | 10 | **0** |
| Preload tax | 21,005 chars | **~10,500** |

Under the 12,000-char success criterion. Per-wave detail is on #99.

## The review fixes

**The gate failed open four ways, three of them found after the retrofit shipped.** An unrecognised follower token made a dangling target vanish. A skill directory with no `SKILL.md` resolved as a valid target, so a commit could be green locally and red in a fresh clone — three existing fixtures were relying on that, one of which made the install-leak A/B pass vacuously. Then the free-standing `/name` sweep turned out to be gated on the sentence carrying a boundary marker, so route notation in any other sentence was invisible — not an ERROR, not a SUGGESTION, not an INFO — which left the documented "`/name` always blocks" promise false from a second direction. All four fixed and pinned.

**Two checks were silently not running.** `validate-provenance.sh` checks 7-8 were dead across nine skills. Waking them exposed a deeper problem: they assume `Research doc:` names a source index, but 30 of 121 entries point at topic content documents, so every new check-7 INFO was a false positive and check 8 was saved from a false-FAIL flood only by an *unannounced* skip. Checks 7/8 are now scoped to source indexes and every skip announces itself (#121).

**The retrofit's own anti-goal, four times.** ADR-0020 warns that a blunt gate gets satisfied by deleting content rather than relocating it. `diagnose` and `skill-audit` relocated prose and then read it unconditionally; `prototype` and `vale-config` deleted rules outright that survived nowhere. All four addressed.

## Verification

- `bash tests/run-tests.sh --strict` — 24 suites, 0 skipped, 0 failed
- `bash tests/run-bats.sh` — 325 tests, 0 failures
- `pre-commit run --all-files` — 17/17
- `pre-commit run --hook-stage pre-push --all-files` — 16/16, with `apm marketplace check` and `apm pack --check-clean` run against the remote, not skipped
- `scripts/skill-size-check.sh` over all 39 skills — rc 0, 0 ERROR/FAIL, SUGGESTION-only
- Preload tax measured at **10,498 chars**, max description 390 — both inside budget
- Every new test proven non-vacuous by a deliberate mutation of the behaviour it covers

**Per-commit sync, stated accurately:** the ten commits from the latest review round each pass `check-plugin-content-sync` in isolation, verified by checking each out in a detached worktree with a clean between. The earlier gitea window (`dfacf05..bedbd1d`, nine commits) does **not** — its mirror was regenerated in one batch at `bbc7300`. An earlier revision of this description claimed the property held for every commit; it does not, and a bisect through that window lands on a red commit. **Squash-merge** to collapse it, or accept that this range is not bisectable.

## Version bump

Six plugins and the catalog take a **patch**, not a minor. The branch is **89 commits — 40 `fix` / 30 `refactor` / 12 `docs` / 5 `chore` / 2 `test` — zero `feat`, zero `!`, zero `BREAKING CHANGE`** — and adds no skill, agent, command or hook. (Two earlier revisions of this section cited a stale histogram, most recently 78 commits; the figures above are measured at HEAD.) Both rules this repo ships (`forge/references/version-bump.md`, landing in this PR, and `git-commits/references/conventional-commits-spec.md`) make that a patch, and the catalog set is unchanged at 7 entries.

Not settled by that: four published files were removed from the installed tree, three moved, and `caveman` gained `disable-model-invocation`, retiring its old triggers. Under a strict reading those are major-class and currently ship under `refactor:` with no marker. Whether the deployed skill surface is a public contract is written down nowhere — worth deciding, but it outlives this PR.

## Deliberately not in scope

#112 (cherry-pick ownership, now resolved in favour of `git-commits`), #113 (`rtk git` normalisation), #116 (research fan-out), #101 (audit-skill merge), #122 (non-spec skill-root files), #123 (no PRD producer) stay open. #117 is the one worth reading: the contract's remedy is to move prose into `references/`, which is exactly where neither the size gate nor Vale looks — and the blind spot is wider than #117 currently records, since there is no root `.vale.ini` at all, so every ADR, `CONTEXT.md` and `README.md` is unlinted too.

That blind spot let this branch carry two `level: error` `Kyberforge.SentenceOpenerThereIs` violations into `references/` files it created — `provider-adapter-author/references/provider-matrix.md:31` and `agent-audit/references/finding-criteria.md:95`. Both are reworded in `afadaae`, confirmed by routing each file through the audit's own `vale-wrap.sh` (1 error each before, 0 after). Five further occurrences sit in `references/` files already on `main`; those are the pre-existing corpus and stay with #117, which is the real fix.

Also unfixed and not this PR's: `apm install` appends a duplicate `SessionStart` entry to `.claude/settings.json`, so a fresh clone cannot get pre-push green without an edit AGENTS.md warns against. Reproduces identically on `main`.

# Rewriting existing commits
Every flow on this page rewrites history. None of them runs before the caller has explicitly approved it, and none is followed by a force-push to `main`/`master` — refuse that and explain why instead.
## Amend the last commit
1. Stage the new changes, or the changes that undo something.
2. Run `rtk git commit --amend`, adding `--no-edit` when the message stays as it is.
3. If the message should change, show the current one and prompt for the replacement.
4. The branch has now diverged from its remote. Amending is safe only on a branch nobody else has based work on; on `main`/`master`, refuse the force-push and explain, rather than warning and proceeding.
## Fold a commit into an earlier one (autosquash — preferred)
Prefer this whenever a commit is written to be folded, because git does the marking:
1. `rtk git commit --fixup=<commit>` keeps the target's message; `rtk git commit --squash=<commit>` lets you edit the combined message later. Both prefix the message with `fixup!`/`squash!` and name the target commit.
2. Get explicit approval — the rebase still rewrites history.
3. Run `rtk git rebase -i --autosquash HEAD~N`. Git pre-fills the todo list with the tagged commits already reordered against their targets; save it unchanged to apply.
**`-i` is not optional here.** On Git 2.39.5, `rtk git rebase --autosquash HEAD~N` without `-i` prints `Successfully rebased and updated refs/heads/<branch>.` and exits 0 while leaving the `fixup!` commit in place at its original SHA — `--autosquash` is honoured only by the interactive machinery, and the false success is the trap: the fold is reported as done, and the surviving `fixup!` subject then fails the Conventional Commits `commit-msg` hook. Later Git versions taught the non-interactive rebase to honour the flag, but `-i --autosquash` is correct on every version, so always write that.
## Squash by hand (interactive rebase)
Use this when the commits were not tagged at commit time. **Interactive rebase has no undo once `rebase -i` starts — `git reflog` is the recovery path.**
1. Identify the commits to squash — typically the last N on the current branch.
2. Get explicit approval.
3. Run `rtk git rebase -i HEAD~N`, marking the older commits `squash` to keep their messages for editing, or `fixup` to discard them.
4. Compose the combined message when the rebase stops to ask. For a non-trivial combined message, follow the structure in `references/commit-template.md`.
## When a rebase halts on a conflict
Offer conflict resolution or `rtk git rebase --abort`. Do not resolve conflicts automatically without confirmation.
## Rebase the branch onto a new base
Replays this branch's commits on top of another branch's tip — bringing a feature branch up to
date without a merge commit.
1. Confirm nothing being replayed has been pushed anywhere someone else has based work on. A rebase
gives every replayed commit a new SHA, which breaks any clone that already has the old ones.
2. Get explicit approval — this rewrites history like every other flow on this page.
3. `rtk git fetch origin` first, so `<newbase>` is the real tip rather than a stale local copy.
4. `rtk git rebase <newbase>` — for example `rtk git rebase main`. Use
`rtk git rebase --onto <newbase> <upstream> <branch>` to replay only the commits after
`<upstream>`, which is how a branch started from the wrong base gets moved.
5. The branch has now diverged from its remote. It needs
`--force-with-lease --force-if-includes` to push, never a bare `--force`, and never on
`main`/`master` — refuse that and explain.
## Move the branch pointer back (`git reset`)
`reset` moves the current branch to another commit. The mode decides what survives:
| Mode | Branch pointer | Index | Working tree |
|---|---|---|---|
| `--soft` | moves | untouched — the changes stay staged | untouched |
| `--mixed` (default) | moves | reset — the changes become unstaged | untouched |
| `--hard` | moves | reset | **overwritten; uncommitted work is destroyed** |
- "Undo my last commit but keep the changes" is `rtk git reset --soft HEAD~1`. That is the default
answer to the request; reach for anything else only when the caller asked for it.
- `rtk git reset --mixed HEAD~1` when the staging should be redone from scratch too.
- `rtk git reset --hard <ref>` is gated like a force-push: state exactly which uncommitted changes
will be discarded, get approval for that specific reset, and offer `rtk git stash push -u` first.
The commits it drops stay reachable through `git reflog`; the uncommitted edits never entered git
at all and nothing recovers them.
Reset does not rewrite the commits it leaves behind, so no force-push is needed unless the branch
was already pushed at the newer commit.
