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 5.1 | $0.00123 | $0.00123 |
| Opus 5 | $0.00062 | $0.00062 |
| Sonnet 5 | $0.00025 | $0.00025 |
| Haiku 4.5 | $0.00012 | $0.00012 |
Grade A, and why
adrs-upsert-only 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 8d 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
ADRs Upsert-Only Policy
docs/adrs/ADRs.mdis upsert-only.- Never rewrite, delete, or reorder existing ADR entries.
- Never modify existing ADR text in place (including ADR 19).
- Additions must be append-only:
- add a new ADR, or
- append a dated addendum section without altering prior content.
- If a request conflicts with this policy, preserve existing ADR content and suggest an append-only alternative.
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.
