agent-symlink-init

name	agent-symlink-init
description	Initialize or migrate agent-skill symlinks in any repository. Use when a project needs `.claude/skills` linked to `.agents/skills`, `AGENTS.md` linked to `CLAUDE.md`, migration away from `.ruler`-based AI rules, or removal of legacy `sync-llm-skills` copy/sync setups. Trigger on requests about Claude/Codex skill symlinks, AGENTS/CLAUDE symlinks, `.claude/skills` setup, replacing copied skill folders with symlinks, or cleaning old ruler/sync automation. Use when this capability is needed.

Agent Symlink Init

Set up or migrate a repository to the symlink-based agent-skill layout.

Outcomes

• Make .agents/skills the source of truth.
• Ensure .claude/skills points at the repository's .agents/skills directory.
• Ensure AGENTS.md is a symlink to CLAUDE.md when CLAUDE.md exists.
• Remove obsolete ruler or sync automation only when it is actually present.
• Keep the migration idempotent and non-destructive.

Detect Before Editing

Work only from the repository root. Require either .git/ or package.json.

Inspect these paths first:

• .agents/skills
• .claude/skills
• CLAUDE.md
• AGENTS.md
• the .ruler directory
• the sync-llm-skills.ts script under the scripts directory
• package.json
• .gitignore

Classify the work into these modules:

1. symlink-init Run when .claude/skills is missing or does not point at the repository's .agents/skills directory, or when AGENTS.md should point to CLAUDE.md but does not.
2. migrate-from-ruler Run when a .ruler directory exists or package.json still contains ruler-related scripts or postinstall fragments.
3. migrate-from-sync Run when a sync-llm-skills.ts file exists under scripts/ or package.json still contains skills:sync:llm or --sync-llm.

Summarize the detected modules before making destructive changes. If the migration will delete the .ruler directory or sync scripts, tell the user exactly what will be removed.

Execute symlink-init

1. Ensure .agents/skills exists:

mkdir -p .agents/skills

2. Ensure .claude exists:

mkdir -p .claude

3. If .claude/skills is a regular directory or file instead of a symlink, preserve it before replacing it:
   • Prefer a backup named .claude/skills.bak
   • If that backup path already exists, choose a timestamped backup name
4. Create or refresh the symlink:

ln -sfn ../.agents/skills .claude/skills

5. If CLAUDE.md exists, ensure AGENTS.md points to it:
   • If AGENTS.md is a regular file, back it up before replacing it

ln -sfn CLAUDE.md AGENTS.md

6. Update .gitignore:
   • Remove any .claude/skills and AGENTS.md ignore entries if they exist. These symlinks must be tracked by git so that collaborators get them on clone.
   • Remove any associated comments (e.g. # Agent skills (symlinked), # START Ruler Generated Files).
   • Do not add new ignore entries for the symlinks.

Execute migrate-from-ruler

Run this module only when ruler artifacts still exist.

1. Remove the .ruler directory.
2. Edit package.json:
   • Remove scripts whose keys clearly belong to ruler automation, such as ruler:apply or ruler:check
   • Remove only the ruler-related fragment from postinstall
   • Remove postinstall entirely if nothing remains
3. Edit .gitignore:
   • Remove ruler-specific ignore entries (e.g. ruler block comments, /CLAUDE.md, /AGENTS.md if they were ruler-generated ignores)
   • Do not re-add /AGENTS.md to .gitignore — the symlink must be tracked by git
4. Do not delete CLAUDE.md unless the user explicitly asks. The goal is to replace the automation mechanism, not to discard the current source-of-truth document.

Execute migrate-from-sync

Run this module only when legacy copy/sync automation is present.

1. Remove the sync-llm-skills.ts file under scripts/ if it exists.
2. Edit package.json:
   • Remove scripts["skills:sync:llm"]
   • Remove only the --sync-llm flag from skills:test:local if the rest of the command is still valid
   • Remove sync-related fragments from postinstall
   • Remove postinstall entirely if nothing remains
3. Edit .gitignore:
   • Remove the .claude/skills ignore entry and any associated comments — the symlink must be tracked by git, not ignored
   • The old ignore was for copy-based sync artifacts; symlinks should be committed
4. Leave .agents/skills contents in place. Migrate the linkage model, not the skill payload itself.

Editing Rules

• Make the smallest safe change set.
• Preserve unrelated package.json scripts.
• When cleaning postinstall, remove only the obsolete command fragment and keep remaining commands in order.
• Skip modules whose signals are absent.
• If the repository already matches the target layout, report that no migration is needed instead of rewriting files.

Verify

Run lightweight checks after editing:

test -L .claude/skills && readlink .claude/skills
test -f CLAUDE.md && test -L AGENTS.md && readlink AGENTS.md

Also inspect:

• package.json for stale ruler or sync commands
• .gitignore for duplicate or contradictory entries
• git diff --stat or equivalent to summarize the migration

Report Back

Return:

1. Which modules ran
2. Which files were created, updated, backed up, or removed
3. Verification results
4. Any follow-up action the user should consider, such as reinstalling dependencies if postinstall behavior changed
