Skill for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

migrate scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Migrate — Schema Upgrade

Purpose

Run schema migration scripts to upgrade vault from current schema_version to target. Idempotent. Backup-first.

Used by wiki-curator.

Trigger phrases

  • "migrate wiki"
  • "upgrade schema to v0.4.0"
  • "apply migration"
  • "schema version mismatch"

Inputs

  • --target schema_version (default = latest plugin version)

Outputs

  • Vault upgraded with bumped schema_version
  • Migration log in wiki/_logs/migration-<chain>-<date>.md
  • Backup at <vault>.bak.v<old>/

Workflow

  1. Read current schema_version from wiki.config.md:

    current=$(lib_read_yaml_key "$VAULT_PATH/wiki.config.md" schema_version)

  2. Determine target version:

    • If --target provided, use it
    • Else use plugin version from ${CLAUDE_PLUGIN_ROOT}/.claude-plugin/plugin.json

  3. Find migration chain:

    • Available scripts: scripts/migrations/v<X>-to-v<Y>/migrate.sh
    • Build chain from current → target (e.g., 0.1.0 → 0.2.0 → 0.3.0 → 0.4.0)
    • If no chain exists, error

  4. Run scripts in order, idempotent:

    for migration in chain:
  "$migration" --vault "$VAULT_PATH"

  5. Verify post-conditions: each migration script does its own verify; in addition, run audit skill at the end.

  6. Print summary with chain executed, pages affected, log location.

Quality gate

  • Each migration idempotent (re-run = no-op)
  • Backup exists at <vault>.bak.v<old>/
  • Post-migration audit reports 0 P0 violations introduced

Anti-patterns

  • DO NOT skip the backup
  • DO NOT manually edit schema_version field — only via migration scripts
  • DO NOT try to migrate non-linearly (skip versions)

Scripts used

  • ${CLAUDE_PLUGIN_ROOT}/scripts/migrations/v0.1.0-to-v0.2.0.sh
  • ${CLAUDE_PLUGIN_ROOT}/scripts/migrations/v0.2.0-to-v0.3.0.sh
  • ${CLAUDE_PLUGIN_ROOT}/scripts/migrations/v0.3.0-to-v0.4.0/migrate.sh
  • After: audit skill for verification

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
