What it does
P4 Code Review is an agent skill from perforce/p4mcp-server. P4 code review workflows — discover, create, vote, comment, transition, and manage reviews via P4 MCP tools. Use when: creating reviews, voting, commenting, transitioning review states, managing participants, or tracking review activity in P4.
Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Code review and MCP servers. It works with Model Context Protocol. The repository describes itself as: [Community Supported] Perforce P4 MCP Server is a Model Context Protocol (MCP) server that integrates with the Perforce P4 version control system. The licence is MIT.
When your agent uses it
- : creating reviews
- Transitioning review states
- Managing participants
- Tracking review activity in P4
Example prompts
- “/p4-code-review”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- modify_changelists → create a pending changelist with your edits
- modify_shelves → shelve the changelist
- modify_reviews → create a review from the changelist
- modify_reviews → append_participants to add reviewers
What it can do on your machine
Read from SKILL.md and the folder at commit a8b284d. 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.
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
P4 Code Review loads about 1.1k tokens when it runs. Until then it costs about 65 tokens; SKILL.md has 429 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.
