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 | $0.00220 | $0.00220 |
| Opus 5 | $0.00110 | $0.00110 |
| Sonnet 5 | $0.00044 | $0.00044 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
obsigna general.instructions.md 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
General review guidelines
This is the Agent Receipts monorepo — cryptographically signed audit trails for AI agent actions.
Security
- Flag any real private keys, secrets, or credentials in the diff.
- Ed25519 is the only supported signing algorithm. Flag any introduction of alternative or weaker schemes.
- Parameters in receipts must be hashed (SHA-256), never stored in plaintext. Flag any plaintext parameter storage.
- Flag any changes to
.github/workflows/— these require explicit maintainer review.
Cross-SDK consistency
- Receipt output must be byte-identical across Go, TypeScript, and Python SDKs.
- Changes to receipt creation, signing, hashing, or canonical JSON in any SDK should be flagged if there are no corresponding cross-language test updates.
Code quality
- Flag unused code, dead imports, and breadcrumb comments ("moved to X", "removed").
- Prefer first-principles fixes over bandaids.
- Flag any
TODOorFIXMEcomments that don't reference an issue number.
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.

obsigna general.instructions.md is an instructions file published in the GitHub repository agent-receipts/obsigna (20 stars, last pushed 3d ago), licensed Apache-2.0. It adds 220 tokens to every session, about $0.0011 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.
