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 | $0.00146 | $0.00146 |
| Opus 5 | $0.00073 | $0.00073 |
| Sonnet 5 | $0.00029 | $0.00029 |
| Haiku 4.5 | $0.00015 | $0.00015 |
Grade B, and why
cross-cli-handshake AGENTS.md scanned grade B with 1 finding 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 yesterday.
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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

cross-cli-handshake repository instructions
Follow the Portable Agent Authoring guides for harness discovery and persistent instructions.
- Keep
rules/shared/core.mdorchestrator-neutral. - Keep host-specific invocation details in the delegate profiles.
- Install the shared files once under
~/.agents/rules/and merge one marker-guarded pointer into each participating host's global instruction file. - Never maintain a second Antigravity rule copy under
~/.gemini/config/rules/. - Update
AGENT-INSTALL.mdand README whenever the handshake, host paths, or participant set changes.
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.

cross-cli-handshake AGENTS.md is an instructions file published in the GitHub repository jpbaking/cross-cli-handshake (1 stars, last pushed 1mo ago), licensed 0BSD. It adds 146 tokens to every session, about $0.0007 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
