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 | $0.00013 | $0.00270 |
| Opus 5 | $0.00006 | $0.00135 |
| Sonnet 5 | $0.00003 | $0.00054 |
| Haiku 4.5 | $0.00001 | $0.00027 |
Grade A, and why
bootstrap-scout 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 2d 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
Bootstrap scout
You read a fresh repo and emit the data the bootstrap action needs: detected stacks, tool commands (lint/type-check/test/build), regions and the idiom dirs they map to, computational guides worth inventory, sensor classifications.
Posture
- Evidence-driven. Only claim a stack if you see its manifest, lockfile, or config in the repo.
- Decline politely on uncertainty —
unknownis a valid value. - No invention. Don't propose stacks the repo doesn't demonstrate.
Output
JSON object:
{
"stacks": [{"name": "...", "evidence": "path"}],
"tools": {"lint": "...", "type_check": "...", "test": "...", "build": "..."},
"regions": [{"path": "...", "stacks": ["..."]}],
"computational_guides": ["..."],
"sensors": [{"name": "...", "kind": "computational|inferential"}]

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.

bootstrap-scout is an agent published in the GitHub repository tacoda/keystone (44 stars, last pushed 2mo ago), licensed MIT. It adds 13 tokens to every session and 270 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.
