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 | $0.01486 | $0.01486 |
| Opus 5 | $0.00743 | $0.00743 |
| Sonnet 5 | $0.00297 | $0.00297 |
| Haiku 4.5 | $0.00149 | $0.00149 |
Grade A, and why
a2amesh AGENTS.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 4d 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 — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.
A2A Mesh Agent Map
What This Repository Is
A2A Mesh is an independent TypeScript monorepo for Agent2Agent-compatible runtime, client, registry, adapters, bridge packages, CLI, docs, and tests.
Use A2A Mesh for human-facing project identity and a2amesh for machine names. All public packages are scoped under @a2amesh/*.
Setup
Use the repository toolchain:
corepack enable
pnpm install --frozen-lockfile
Supported runtime is Node.js >=22.22.1 <25 and pnpm >=11 <12.
Build And Test
Run the narrowest relevant command first, then the broader gate:
pnpm run lint
pnpm run typecheck
pnpm run test
pnpm run build
pnpm run verify
pnpm run verify is the local release-quality gate. Do not bypass failing checks.

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.
