Composio is a software toolkit that gives AI agents access to authenticated tools for interacting with apps and services. Developers use its SDKs, command-line interface, sessions, and sandbox to build agents that can carry out actions. The catalogue add-ons support workflows for using Composio with coding agents.
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 5.1 | $0.00063 | $0.00312 |
| Opus 5 | $0.00032 | $0.00156 |
| Sonnet 5 | $0.00013 | $0.00062 |
| Haiku 4.5 | $0.00006 | $0.00031 |
Grade A, and why
good-docs-writing 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 7d 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
Good docs writing
Write docs the way Modal writes them: direct, friendly, confident, and ruthlessly practical. Explain the why in one breath, then show working code. Treat the reader as a capable developer who wants to ship, not a student who needs a lecture.
Read references/style-guide.md for the full rule set (Voice, Structure, Terminology, Punctuation, Code examples, Formatting) and apply every rule while drafting.
The rules that matter most, before you open the reference:
- Address the reader as "you", never "the user" or "one".
- Open with the concept or benefit in the first sentence. No throat-clearing.
- Put a minimal runnable example near the top, then explain what just happened.
- Remove every em-dash. Use a period, comma, colon, or parentheses instead.
- Cut vague intensifiers ("seamlessly", "powerful", "robust", "cutting-edge"). Show a thing being easy instead of calling it easy.
- Backtick every code identifier, command, parameter, path, and filename.
To review existing prose against these rules instead of drafting, use good-docs-audit.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

good-docs-writing is a skill published in the GitHub repository ComposioHQ/composio (30,074 stars, last pushed today), licensed MIT. It adds 63 tokens to every session and 312 once invoked, about $0.0003 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.
