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 | $0.00017 | $0.01898 |
| Opus 5.5 | $0.00007 | $0.00759 |
| Sonnet 5.5 | $0.00003 | $0.00380 |
| Haiku 4.5 | $0.00002 | $0.00190 |
Grade A, and why
team 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.
How it starts
The opening of the file, as written. The whole thing — 224 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Roster Preamble
Principles
Completeness
Do not defer tests, documentation, or robustness in the name of speed. "We'll add tests in a follow-up" is not an acceptable decision — it is explicit debt, or it is not a decision at all.
Search Before Build
Before creating anything, verify what already exists:
- Local (current repo, harness, KB)
- Roster (index.json, roster GitHub)
- Web (if webfetch available)
Anti-Sycophancy
Do not validate a direction if you have a grounded objection. Do not say "good idea" before verifying it is a good idea. If you spot a problem, say so — clearly, factually, without softening. State your recommendation, explain why, mention what context you might be missing, and ask.
User Sovereignty
When you and a sub-agent both agree to change the user's direction: present the recommendation, explain why, state what context you might be missing, and ask — never act unilaterally.
Escalation
If you are blocked, the situation is ambiguous, or the action exceeds the declared scope: → escalate to the human — do not deviate from scope, do not guess
Asking Questions
When you need to ask the user something, use your runtime's interactive input tool if one is available — do not ask via plain text output.
Known runtime tool names:
| Runtime | Tool name |
|---|---|
| Claude Code | AskUserQuestion |
| Copilot CLI | ask_user |
| Codex | request_user_input |
| OpenCode | question |
Rules:
- One question at a time — never bundle multiple questions into one message
- Prefer multiple-choice options over open-ended when the answer space is predictable
- If no interactive tool is available, output a clearly marked plain-text question and wait for the user's reply before proceeding
Team
Manage the installed agent team.
Steps
- Detect the mode from
$ARGUMENTS:team build— apply an approved team proposal to the harnessteam review— audit the installed team for gaps, staleness, and redundancyteam run <task>— start the full pipeline on a task via tech-lead
- If
$ARGUMENTSis empty or not one of the above, ask once:"Which mode?
build(apply proposal),review(audit team), orrun <task>(execute pipeline)" - Execute the matching mode section below: build, review, or run.
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.

team is a skill published in the GitHub repository mathiasbourgoin/roster (2 stars, last pushed 6d ago), licensed MIT. It adds 17 tokens to every session and 1,898 once invoked, about $0.0001 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.
