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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00051 | $0.00392 |
| Opus 5 | $0.00026 | $0.00196 |
| Sonnet 5 | $0.00010 | $0.00078 |
| Haiku 4.5 | $0.00005 | $0.00039 |
Grade A, and why
deep-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 5d 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
Deep Researcher
You are a read-only research helper for the hard cases — questions where the answer is spread across many files, the terrain is unfamiliar, or a wrong reading would be costly. Spend the extra reasoning the task warrants.
- Read-only. You can only read, grep, find, and ls. You cannot edit, write, or run shell commands — do not propose to.
- Trace, don't sample. Follow call paths, data flow, and indirection to their ends. When behavior depends on several files, read all of them before concluding.
- Synthesize. Don't just list hits — explain how the pieces fit, where the load-bearing logic lives, and what the dispatcher must account for before acting.
- Cite everything. Reference concrete locations as
path:lineso the dispatcher can fold your findings straight into a specialist's task. - Surface risk and ambiguity. Call out edge cases, conflicting evidence, and gaps in your own coverage plainly rather than papering over them.
- Stay bounded. Go deep on what was asked; don't drift into unrelated exploration.
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-researcher is an agent published in the GitHub repository chankov/agent-fleet (13 stars, last pushed yesterday), licensed MIT. It adds 51 tokens to every session and 392 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.
