What it does
Cross Agent Review is an agent skill from prassanna-ravishankar/repowire. Get a code/PR/plan review from a DIFFERENT AI agent over the repowire mesh (e.g. have Codex review Claude's work). Use when you want an independent second opinion from another backend before merging or committing.
Its SKILL.md is about 480 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Model Context Protocol. The repository describes itself as: May the agents talk . Connect Claude Code, Opencode, Codex, Pi across projects, across machines and with your telegram.
When your agent uses it
- You want an independent second opinion from another backend before merging
Example prompts
- “/cross-agent-review”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- Explicit argument — if the user named a backend (e.g. "review with codex"), use it.
- Configured default — else read it
- Safe fallback — if still unset, pick any *online peer whose backend differs
What it can do on your machine
Read from SKILL.md and the folder at commit 7c8100a. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Cross Agent Review loads about 480 tokens when it runs. Until then it costs about 58 tokens; SKILL.md has 242 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 242 words (~480 tokens).
“Ask a peer running a different agent backend to review your work, so the review is genuinely independent (not the same model checking itself).”
