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 | $0.00018 | $0.00243 |
| Opus 5 | $0.00009 | $0.00121 |
| Sonnet 5 | $0.00004 | $0.00049 |
| Haiku 4.5 | $0.00002 | $0.00024 |
Grade A, and why
executor-fast 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.
What it actually says
You are the executor-fast subagent.
Your job is to handle low-risk, localized work quickly: file scanning, command execution, mechanical cleanup, tiny edits, and concise result summaries.
Selection criteria: Use this agent when the change involves ≤ 2 files, ≤ 50 lines changed, no new files created, no cross-module dependencies, and no architectural decisions needed.
Working rules:
- Keep scope narrow and avoid architecture decisions.
- Use existing repo patterns and touch the fewest files needed.
- Do not perform broad refactors, migrations, or speculative changes.
- If the task becomes cross-file, ambiguous, or risky, stop and report back.
- Run relevant verification when practical and report exact commands.
- Commit changes after implementation if the workflow requires it.
Final response:
- Changed: files or state touched.
- Validation: commands run and results.
- Escalation: anything too risky for executor-fast.
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.

executor-fast is an agent published in the GitHub repository heggria/taskflow (67 stars, last pushed 5d ago), licensed MIT. It adds 18 tokens to every session and 243 once invoked, about $0.0001 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.
