critty-ai-cowork

critty-ai-cowork is a skill for Claude Code, Codex from crittylabs/critty. It costs 62 tokens per session (655 once invoked), scanned A, original, MIT.

A way to work with another AI through Critty while refining a requested change between review rounds. It carries the task's target and checks forward, lets the collaborating AI suggest or make authorized fixes, and leaves the final decision to a human.

In plain words
What is it for?
Use it when a human asks for collaboration with a named AI, or when review findings need an exchange and authorized follow-up changes before final human review.
Why use it?
Some tasks need more than a one-time second opinion: findings may need questions, counterexamples, fixes, and another review. This keeps that collaboration tied to the same requested outcome and permissions.

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

critty-ai-cowork 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 yesterday.

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.

The opening of the file, as written. The whole thing — 33 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cowork with Another AI

Experimental: interfaces and supported launch configurations may change.

Read critty-ai-review and follow its requester workflow, request identity, snapshot, posting, and completion contracts. This skill changes only how the requester acts between AI review rounds. Keep its reviewer role unchanged.

A request such as /critty-ai-cowork with Astra selects a collaborator for the current task and authorizes in-scope fixes and follow-up between agents. Follow the shared skill's with argument handling. Establish the target outcome and acceptance checks before dispatch, using existing task context. If the request only asks for an opinion, use critty-ai-review instead. Preserve the user's selected collaborator and the caller's execution permissions.

Replace the per-round checkpoint

After collecting and verifying each AI result:

  1. Assess the findings against the requirements and evidence. Exchange focused questions or counterexamples with the reviewer when needed; agreement alone is not evidence of correctness.
  2. Make authorized fixes and run the affected checks as the requester. The other AI reads, posts findings, replies to its own threads, and resolves its own verified findings through the restricted Critty interface; it does not edit files or execute checks.
  3. Capture the revised target and request review of the affected scope, explicitly carrying forward unresolved findings and permitting the reviewer to resolve its own findings after verification. Reuse valid results for unchanged content. Keep each assignment tied to its own version and completion report.

For a one-shot reviewer that has exited, continue an exchange by posting the requester's question or evidence as a reply, then launching a new assignment with a new request ID and references to that thread and the prior result. A live transport may continue on its existing handle. An exited process cannot receive another question merely by waiting on it.

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.
