Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00030 | $0.04721 |
| Opus 5 | $0.00015 | $0.02361 |
| Sonnet 5 | $0.00006 | $0.00944 |
| Haiku 4.5 | $0.00003 | $0.00472 |
Grade A, and why
deep-review 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 2d 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 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.

deep-review is a skill published in the GitHub repository coder/coder (14,299 stars, last pushed 2d ago), licensed AGPL-3.0. It adds 30 tokens to every session and 4,721 once invoked, about $0.0002 per session on Opus 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 2026-08-30.

chart
Use when the user asks to visualize data with charts, graphs, or plots using the chart tool (bar, line, scatter, pie, time series, etc.).
ultracite
Ultracite is a zero-config linting and formatting preset for JavaScript/TypeScript projects. Use when: (1) Setting up or initializing Ultracite in a project (ultracite init), (2) Running linting or formatting commands (check, fix, doctor), (3) Writing or reviewing JS/TS code in a project that uses Ultracite — to…
workflows
Execute a workflow script that orchestrates multiple subagents deterministically. Use when the user explicitly requests a workflow, multi-agent orchestration, parallel or sequential agent pipelines, structured agent outputs, or a durable background workflow run.
submit-a-plugin
Submit a bb plugin to the BB Community marketplace. Use whenever a user asks to submit, list, publish, or add a plugin to the BB marketplace, or asks for a marketplace pull request. This skill validates the plugin and release, creates the marketplace entry and icon, and opens the pull request.
secrets
Securely request API keys, access tokens, passwords, webhook secrets, or other credentials and write them to a dotenv file without exposing their values to the agent. Use whenever a task needs a credential that the user must supply.
planning
Create structured plan documents and track work items using YAML frontmatter. Use when the user wants to plan a feature, track progress, log bugs/tasks/ideas, or organize project work.
