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 | $0.00028 | $0.00256 |
| Opus 5.5 | $0.00011 | $0.00102 |
| Sonnet 5.5 | $0.00006 | $0.00051 |
| Haiku 4.5 | $0.00003 | $0.00026 |
Grade A, and why
agent-interop 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 1mo 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
Agent Interoperability
Treat .agents/skills/ as the portable, repository-scoped skill layer. Keep runtime-specific configuration in the runtime’s own file and link back to the portable skill instead of duplicating its logic.
- Codex discovers project skills from
.agents/skills/and project MCP settings from.codex/config.toml. - Claude Code uses
.claude/skills/and project MCP settings from.mcp.json; when a portable skill is not mirrored there, read the corresponding.agents/skills/<name>/SKILL.mdexplicitly. - Hermes can discover the same tree through
skills.external_dirsin~/.hermes/config.yaml; external skill directories are read-only discovery sources. - Keep tool names, schemas, approval expectations, and verification steps in the shared documentation. Do not rely on one runtime’s permission model being honored by another.
When transferring work, pass objective, scope, assumptions, files changed, tool calls made, evidence, unresolved risks, and the next verification step. Prefer a small handoff record over copying hidden conversational state.
What ships with it
2 files 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.

agent-interop is a skill published in the GitHub repository docxology/codomyrmex (11 stars, last pushed today), licensed MIT. It adds 28 tokens to every session and 256 once invoked, about $0.0001 per session on Opus 5.5. 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.
