publish-skill

name	publish-skill
description	Detect new or modified skills in .agents/skills/ by comparing git hashes against ai-skills, snapshot for rollback, review, publish to ai-skills, install locally, and cherry-pick lockfile to TARGET. Replaces /elevate-skill.

When to invoke

• User says "publish skill", "update skill", "push skill changes", "/publish-skill"
• After editing a skill locally in .agents/skills/

Steps

1. Pre-flight

Locate ai-skills path (in order):

1. $AI_SKILLS_REPO env var
2. ~/projects/camacho/ai-skills
3. Ask user

Then check it's clean:

git -C "$AI_SKILLS_PATH" status --porcelain

If non-empty: STOP. Tell user to commit or stash ai-skills changes first.

2. Detect new and modified skills

For each directory in .agents/skills/:

skill_name=$(basename "$dir")
local_hash=$(git hash-object ".agents/skills/$skill_name/SKILL.md" 2>/dev/null)
remote_hash=$(git hash-object "$AI_SKILLS_PATH/skills/$skill_name/SKILL.md" 2>/dev/null || echo "")

Classify:

• remote_hash empty → 🆕 NEW
• local_hash != remote_hash → ✏️ MODIFIED
• equal → unchanged, skip

Present list. Ask for confirmation before proceeding. Record each local_hash — needed for the safety check in Step 7.

3. Snapshot (rollback point)

For each approved skill:

git add -f ".agents/skills/$skill_name/SKILL.md"
git commit -m "chore(skills): snapshot $skill_name before publish [publish-skill rollback point]"

If publish fails at any later step, restore with:

git checkout ".agents/skills/$skill_name/"

4. Code review

Run code-reviewer agent on the SKILL.md diff (local vs ai-skills version). Review focus: correctness, no dangerous bash, no prompt injection vectors.

P0/P1 findings → STOP. Fix before proceeding. P2 findings → note but don't block.

5. Copy to ai-skills and push

cp -r ".agents/skills/$skill_name" "$AI_SKILLS_PATH/skills/$skill_name"
git -C "$AI_SKILLS_PATH" add "skills/$skill_name"
git -C "$AI_SKILLS_PATH" commit -m "feat(skills): publish $skill_name"

After all skills committed:

git -C "$AI_SKILLS_PATH" push

Confirm with user before pushing — this affects all repos using these skills.

6. Install locally

Detect scope for each skill — check which lockfile it belongs in:

REPO_ROOT="$(git rev-parse --show-toplevel)"
if jq -e --arg n "$skill_name" '.skills[$n]' "$REPO_ROOT/dotfiles/skills-lock.json" >/dev/null 2>&1; then
  SCOPE="user"
else
  SCOPE="project"
fi

npx skills add uses process.cwd() as the install target. In a linked worktree, ensure CWD is the worktree root.

Source spec: use the github <owner>/<repo> form, NOT a local filesystem path. A local path produces lockfile entries with sourceType: "local" and a machine-specific source, which conflicts with the sourceType: "github" entries other repos use and breaks merges. Detect the canonical spec from the ai-skills remote so it works across machines:

AI_SKILLS_SPEC=$(git -C "$AI_SKILLS_PATH" remote get-url origin \
  | sed -E 's#(git@github\.com:|https://github\.com/|ssh://git@github\.com/|git://github\.com/)##; s#\.git$##; s#/$##')
# e.g. "camacho/ai-skills"

# Validate — bad spec must fail loudly, not silently re-introduce sourceType=local class of bug.
[[ "$AI_SKILLS_SPEC" =~ ^[^/]+/[^/]+$ ]] || { echo "bad spec: $AI_SKILLS_SPEC"; exit 1; }

cd "$REPO_ROOT"
if [ "$SCOPE" = "user" ]; then
  npx skills add "$AI_SKILLS_SPEC" --skill "$skill_name" -g -a claude-code -a codex -y
else
  npx skills add "$AI_SKILLS_SPEC" --skill "$skill_name" -a claude-code -a codex -y
fi

The github spec requires the source commit to be pushed first (Step 5 already pushes), so the install pulls the same content you just published.

npx skills add updates the appropriate skills-lock.json automatically.

7. Safety hash check

For each installed skill:

after_hash=$(git hash-object ".agents/skills/$skill_name/SKILL.md" 2>/dev/null)

Compare after_hash against the pre-publish local_hash from Step 2.

If mismatch:

• Restore: git checkout ".agents/skills/$skill_name/"
• Alert user. STOP.

8. Drop tracking + commit lockfile

for skill_name in $approved_skills; do
  git rm --cached ".agents/skills/$skill_name/SKILL.md"
done
# Stage the lockfile that was updated (project or user)
git add skills-lock.json dotfiles/skills-lock.json 2>/dev/null || true
git commit -m "chore(skills): publish $approved_skills_csv — drop tracking, update lockfile"

LOCKFILE_SHA=$(git rev-parse HEAD)

9. Cherry-pick lockfile commit to TARGET

Default TARGET=main. Check for conflict:

git fetch origin "$TARGET"
git checkout "$TARGET"
git cherry-pick --no-commit "$LOCKFILE_SHA"
git status --porcelain

If conflict on skills-lock.json: STOP. Surface to user. If clean: git cherry-pick --continue (or git commit after --no-commit), then push.

If CI is down: invoke /local-merge with BRANCH=current, TARGET=$TARGET instead of cherry-pick + push.

Integration

Replaces: /elevate-skill (which only handled local-only skills). Pairs with: /build-skill (creates new skills) and /local-merge (CI-down fallback for Step 9).
