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

plugin-forge 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 1mo 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

plugin-forge — lint + scaffold Claude Code plugins

Lint

  • One plugin: python3 plugins/plugin-forge/pluginforge/lint.py <plugin-dir>
  • Whole marketplace: python3 plugins/plugin-forge/pluginforge/lint.py --all --strict
  • --strict adds house invariants (stdlib-only, verify.py, test_no_third_party). Exits 1 on any HARD.

Scaffold

  • python3 plugins/plugin-forge/pluginforge/scaffold.py <name> → a skeleton that passes lint --strict.
  • Then add it to marketplace.json + CI and flesh out the TODOs.

The lint report is a DRAFT; a human decides. HARD = fails CI; SOFT = advisory.

Changes

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.
