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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.01320 |
| Opus 5 | $0.00000 | $0.00660 |
| Sonnet 5 | $0.00000 | $0.00264 |
| Haiku 4.5 | $0.00000 | $0.00132 |
Grade A, and why
compatibility-matrix 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 5d 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 — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent compatibility matrix
HM-Arch integrates with four coding agents. This matrix summarizes what the
packaged hm-arch CLI supports today and where manual configuration is
required.
Summary
| Capability | Codex | Claude Code | Hermes | OpenClaw |
|---|---|---|---|---|
Hook / plugin install via hm-arch install |
Yes | Yes | Yes (native plugin bridge) | Yes (memory plugin + sidecar) |
hm-arch status / doctor |
Yes | Yes | Yes | Yes |
hm-arch doctor --fix (safe config repair) |
Yes | Yes | No | No |
| Recall / record / consolidate hooks | Yes | Yes | Via plugin | Via plugin + sidecar |
| Project-scoped memory | Yes | Yes | Yes | Yes |
| Global-scoped memory | Yes | Yes | Yes | Yes (--global) |
| Shared database with other agents | Yes | Yes | Yes | Yes |
| Offline operation (no API keys) | Yes | Yes | Yes | Yes (management CLI) |
npm hm-arch-install install |
Yes | Yes | Yes | Yes |
Codex
| Feature | Support | Notes |
|---|---|---|
| Install / uninstall hooks | Supported | hm-arch install codex / uninstall codex |
| Project vs global scope | Supported | Default project; --global for ~/.codex |
| Doctor diagnostics | Supported | Hooks, config.toml feature flag, executables |
Doctor --fix |
Supported | Re-installs partial hooks and re-enables [features].hooks |
Missing hm-arch on PATH |
Degraded | Hooks fall back to python -m hm_arch.integrations.cli |
Missing codex CLI |
Warning only | Hooks still run when Codex invokes them |
Claude Code
| Feature | Support | Notes |
|---|---|---|
| Install / uninstall hooks | Supported | hm-arch install claude-code |
| Project vs global scope | Supported | Default project; --global for user settings |
| Doctor diagnostics | Supported | Hooks, executables, config directory |
Doctor --fix |
Supported | Re-installs partial hook sets |
Missing hm-arch on PATH |
Degraded | Same Python module fallback as Codex |
Missing claude CLI |
Warning only | Does not block hook execution |
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.

compatibility-matrix is an agent published in the GitHub repository zhhjluka/hm-arch (18 stars, last pushed 2mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,320 tokens. 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.
