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 | $0.00074 | $0.02261 |
| Opus 5 | $0.00037 | $0.01130 |
| Sonnet 5 | $0.00015 | $0.00452 |
| Haiku 4.5 | $0.00007 | $0.00226 |
Grade A, and why
ad-bootstrap 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.
How it starts
The opening of the file, as written. The whole thing — 191 lines — stays where its author put it; the contents beside it link to each section on GitHub.
<background_information>
Produces AGENTS.md at the repo root, ≤150 lines, every line operational. Generic agent behavior (think-before-coding, verify-before-claiming-done, etc.) does NOT belong here — that lives in the ad-philosophy skill.
Three modes, detected from filesystem state:
AGENTS.mdexists at the repo root → audit (do not rewrite, output drift list only)AGENTS.mdabsent and only trivial files present (.git,node_modules,.gitignore,.gitattributes,.DS_Store,.env*,.idea,.vscode,LICENSE*,README.md) → greenfield (interview by placeholder, no scan)AGENTS.mdabsent and meaningful code present → brownfield (scan first, pre-fill, ask only gaps) </background_information>
Step 1 — scan (brownfield only). Read in this order, taking the first that exists for each category:
- Manifests:
package.json,pyproject.toml,Cargo.toml,go.mod,Gemfile,composer.json,pubspec.yaml. README.md, plus anydoc/ordocs/directory.- Top-level directory listing.
doc/adr/— binding decisions; read every ADR.GUIDELINES.mdat repo root — if present, the AGENTS.md sections that have a corresponding GUIDELINES.md section (Code Style → §2; Quality Gates → §8; Commit & PR → §10; Security & Privacy → §12) emit as pointer stubs instead of inline rules' ' reciprocity and ADR-0030 §1..claude/,.cursor/,.openai/,.agents/— existing agent config.- Hook configs:
.husky/,.pre-commit-config.yaml,.github/workflows/,.gitlab-ci.yml,.circleci/. - Lockfiles:
package-lock.json,yarn.lock,pnpm-lock.yaml,poetry.lock,Cargo.lock. git remote -vfor the repo URL.
Build a model of: stack (languages and versions), entry points, build / test / lint commands, conventions, quality gates, security boundaries, gotchas confirmed by code.
Step 2 — pre-fill. For every <placeholder> in the template, fill from observed signals. No fabrication. If a section has no signal, write <TODO: not yet wired> in one line and move on. Do not write meta-prose explaining the gap.
Step 3 — show only the gaps. Print to the user:
- (a) placeholders that could not be filled from repo signals;
- (b) signals that conflict (two test commands, two style configs, README contradicts code, etc.).
One question per gap. Skip everything filled confidently. Do NOT ask philosophical questions ("is this doc for agents or humans?", "what is the most important quality bar?") — those are decisions, not interview material.
Step 4 — write the file. On user confirmation, write AGENTS.md at the repo root. Cut every line that does not change agent behavior. No "External Resources" section (URLs are derivable from git remote and the manifest). No appended Universal Agent Behavior block. No marketing prose.
Audit-mode override: do NOT write the file. Produce a drift list. Format each line as:
[file or section]: spec says X, code says Y. Suggested resolution: change spec / change code / discuss.
If something the user says contradicts what the code shows, surface the conflict. Don't silently trust the user; don't silently trust the code.
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.

ad-bootstrap is a skill published in the GitHub repository CorridorTech/PoseCap (190 stars, last pushed 9d ago), licensed Apache-2.0. It adds 74 tokens to every session and 2,261 once invoked, about $0.0004 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.
