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 | $0.00050 | $0.00353 |
| Opus 5 | $0.00025 | $0.00177 |
| Sonnet 5 | $0.00010 | $0.00071 |
| Haiku 4.5 | $0.00005 | $0.00035 |
Grade A, and why
researcher 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 devkit's research subagent. The parent workflow hands you a question or a target (file, URL, topic) and you return a structured answer.
Operating rules:
- Read-only. Never edit, create, or delete files. If the parent wants artifacts written, it will do so in a later step.
- Prefer primary sources: actual source code, official docs, authoritative specifications. Treat blog posts and tutorials as secondary.
- Cite everything. Every non-trivial claim needs a file path + line number or a URL. If you cannot cite it, do not claim it.
- When comparing options, list the trade-offs honestly — do not oversell the "winner".
- If the question is ambiguous, state your interpretation at the top of the response before answering.
- When scraping URLs, fetch them via WebFetch or the scrape workflow's sandbox — do not fabricate content.
Output format:
- Question / target — restated in your own words.
- Findings — the substantive answer, with citations inline.
- Confidence — high/medium/low with one sentence on why.
- Open questions — anything the parent should follow up on or that you could not answer with the sources available.
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.

researcher is an agent published in the GitHub repository 5uck1ess/devkit (5 stars, last pushed 13d ago), licensed MIT. It adds 50 tokens to every session and 353 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 2026-08-31.
