A legacy helper directory for routing prompts and verification messages through provider-native hooks, with optional monitoring through tmux, a terminal session manager.

It is for using native Codex or Claude hooks, sending local verification files, monitoring tmux sessions, and resubmitting prompts to running sessions.

It warns that its older installation workflow is no longer the main path, helping users avoid relying on migration-only commands.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00178
Opus 5.5	$0.00000	$0.00071
Sonnet 5.5	$0.00000	$0.00036
Haiku 4.5	$0.00000	$0.00018

Security

Grade A, and why

omc 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 2mo 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

Legacy wrapper helper note

This helper directory is no longer the recommended public workflow.

Use provider-native Codex or Claude hooks, rely on git repo/worktree context for routing identity, and send local verification payloads through:

clawhip native hook --provider codex --file payload.json
clawhip native hook --provider claude --file payload.json

tmux monitoring remains available for keyword/stale alerts, but provider-native hook registration is now the primary integration path.

If you need to re-submit a prompt into an already-running tmux-backed provider session, use:

clawhip deliver --session <tmux-session> --prompt "..." --max-enters 4

Legacy clawhip hooks install --scope project flows are migration-only shims; rerun the default global install path for supported setups.

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.
