agent-compatibility

agent-compatibility is a skill for Claude Code, Codex from moasq/agentic-ship. It costs 73 tokens per session (1,552 once invoked), scanned A, original, MIT.

A guide for keeping one set of project rules, procedures, specialist roles, and tool settings working across AI coding hosts such as Claude, Codex, Cursor, Hermes, and OpenClaw.

In plain words
What is it for?
Use it to configure host adapters, expose the same tools on multiple hosts, synchronize changes, and check for configuration differences.
Why use it?
It prevents different host-specific copies from drifting apart and behaving inconsistently.

Install

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.

npx agentmods add skills/moasq/agentic-ship/agent-compatibility
Any agent
npx skills add moasq/agentic-ship --skill agent-compatibility
Clone the repo

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

agent-compatibility 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 today.

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 — 132 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Agent compatibility

Preserve one authored system and generate only the host syntax needed to expose it. Treat a native adapter as delivery machinery, never as a second home for doctrine.

Keep the canonical layer singular

Use these sources as the authority:

Concern Canonical source
repository rules AGENTS.md
procedures .agents/skills/*/SKILL.md
dispatch roles .agents/agents/*.md
MCP inventory .mcp.json
product and handoff contracts .agents/contracts/

Change the canonical source first. Regenerate an adapter after the source change. Never repair drift by editing a generated Claude plugin, Codex, Cursor, Hermes, or OpenClaw file directly. Never restate an AGENTS.md rule inside an adapter or skill.

Synchronize native adapters

Run the write pass after changing a canonical role or .mcp.json:

pnpm sync:agents

Run the read-only drift check after install and before completion:

pnpm check:agents

Run the MCP mirror check separately:

pnpm check:mcp

Treat any generated-file drift as a local configuration defect. Re-run the matching sync command; do not copy content by hand. Run pnpm health afterward to check the rest of the static workspace contract.

Use the native surface for each host

Host Rules and skills Native roles MCP and enforcement
Claude Code CLAUDE.md imports AGENTS.md; .claude/skills resolves to .agents/skills .claude/agents resolves to canonical roles in-project; generated top-level agents/ ships the plugin roles .mcp.json; plugin wiring and the completion hook live in .claude/settings.json
Codex reads AGENTS.md and project skills generated .codex/agents/*.toml generated project-scoped .codex/config.toml, including direct MCP URLs
Cursor reads AGENTS.md and Agent Skills generated .cursor/agents/*.md generated .cursor/mcp.json; use native hooks when a checked adapter declares them
Hermes reads AGENTS.md; .hermes/profile/config.yaml adds .agents/skills through skills.external_dirs .hermes/profile/SOUL.md and the generated role catalog drive delegate_task from canonical briefs generated profile entry for the local Agentic Ship server; configure OAuth MCP in the selected profile or user config and keep tokens outside the repository
OpenClaw reads AGENTS.md and discovers .agents/skills natively with this repository as the agent workspace; .openclaw/config.json5 is the non-secret template for any other workspace generated .openclaw/roles.md drives sessions_spawn from canonical briefs generated template entry for the local Agentic Ship server; configure OAuth MCP with the host CLI in user configuration and keep tokens outside the repository

Files

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.

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.

agent-compatibility is a skill published in the GitHub repository moasq/agentic-ship (11 stars, last pushed 3d ago), licensed MIT. It adds 73 tokens to every session and 1,552 once invoked, about $0.0004 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 2026-08-31.
