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 5.1 | $0.00074 | $0.02360 |
| Opus 5.5 | $0.00030 | $0.00944 |
| Sonnet 5.5 | $0.00015 | $0.00472 |
| Haiku 4.5 | $0.00007 | $0.00236 |
Grade A, and why
claude-collab 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 9d 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Claude Code peers
Claude Code sessions in this workspace are peers you can collaborate with: delegate a task, divide implementation work, or review each other's output. Each is a separate agent with its own context, working in the same directory — often the session the user is talking to in another terminal.
codex-collab is the whole path to them: it records every message as a task and keeps its reply, and it starts, resumes and stops the sessions it hands work to. A session started any other way (claude --bg, a terminal) is outside most of that: send can message it while it is live, but codex-collab never stops it, peers stop refuses it, and it is never resumed.
Commands
codex-collab peers # who is live here: name, idle or busy, kind
codex-collab send <name> "message" # hand that session a task and wait for its reply
codex-collab send "message" # the only live session (the user's, if theirs is the one), or one started for you
codex-collab send --new "message" # a new session started for you, even while the user's is live
codex-collab task wait <id> # go on waiting for a task's reply
codex-collab task result <id> # print a task's reply, if it has come
codex-collab task status <id> # where a task stands
codex-collab tasks # all tasks sent from this workspace
codex-collab peers stop [<name>] # stop a session codex-collab started
codex-collab send --help # which session each form of send reaches; every option
Every send is a task with an id, printed when the message is delivered. --timeout <sec> (default 600) bounds how long the command waits. The task continues past it for four hours from sending (or the --timeout, if longer), not counting time a session codex-collab started spends at a prompt the user can answer through Remote Control, and with at least 60 minutes (config linger) after the user answers one; a reply in that time is kept under the id; after that the task is expired. --no-wait returns once the message is delivered; task wait <id> collects the reply afterwards. --file <path> reads the message from a file inside the folder this Codex session works in; - reads it from stdin.
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.

claude-collab is a skill published in the GitHub repository Kevin7Qi/codex-collab (98 stars, last pushed 6d ago), licensed MIT. It adds 74 tokens to every session and 2,360 once invoked, about $0.0003 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 2026-09-29.
