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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.01404 | $0.01404 |
| Opus 5.5 | $0.00562 | $0.00562 |
| Sonnet 5.5 | $0.00281 | $0.00281 |
| Haiku 4.5 | $0.00140 | $0.00140 |
Grade A, and why
claude-code-plugins AGENTS.md 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 yesterday.
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.
How it starts
The opening of the file, as written. The whole thing — 75 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Code Plugin Marketplace
One directory per plugin, listed in .claude-plugin/marketplace.json.
Plugin Work
Do not reinvent plugin patterns. Delegate:
/plugin-dev:create-pluginand theplugin-devskills (structure, skills, hooks, agents, settings) to build or modify a pluginplugin-dev:plugin-validatoragent to validate oneclaude-code-guideagent for Claude Code behavior questions- Live doc search: the
claude-code-docsMCP server (user scope, https://code.claude.com/docs/mcp) - Official docs, the fallback when those are not installed: https://code.claude.com/docs/en/plugins
New plugin: add its marketplace.json entry and its README.md table row by hand; no check catches their absence. A plugin's version and description live in its plugin.json alone.
Agents never bump a version or write a CHANGELOG.md section: scripts/release.ts does both at release time.
For plugin tests, permissions and the catalog lifecycle, start at Plugin testing and open only the page for the task. The vellum and atlas plugins carry their own AGENTS.md; vellum's .claude/rules/ have paths: relative to vellum/.
Commands
bun test --parallel # every suite outside dot directories and `archive/`
bun test --parallel ./.claude/hooks/*.test.ts # the repo's own hooks; `bun test` skips them
bun ./scripts/run-gates.ts # CI's `validate` gates for what the change reaches (`--all`: everything)
bun ./scripts/affected.ts print # what the change reaches since origin/dev; `test` runs those suites
bun ./scripts/land.ts <branch> # land a branch on dev; run once in the background, its last line says what to do next
bun run --cwd vellum e2e # vellum's browser suite; Chromium once per machine: `bun run --cwd vellum e2e:install`
vellum/, pinpoint/ and atlas/ carry package.json + bun.lock: bun install --cwd <plugin> --frozen-lockfile before their tests or their server.
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.

claude-code-plugins AGENTS.md is an instructions file published in the GitHub repository bengous/claude-code-plugins (6 stars, last pushed yesterday), licensed MIT. It adds 1,404 tokens to every session, about $0.0056 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
