PRP Companion Page

What it does

When your agent uses it

• Turning a PRP plan into a one-page visual with a diagram and risks
• Presenting a pull request review as a verdict, findings and change diagram
• Making a plan easier for a teammate to skim before approving it
• Tracking finding or step status on a live page in helm

Example prompts

• “Make the latest plan visual with a companion page.”
• “Visualize pr-12-review.md so I can go through the findings one by one.”
• “Diagram this plan and write the companion page for auth-rework.plan.md.”

Requirements

• A PRP plan or review markdown file, such as one written by prp-plan or prp-review
• Git, used to resolve the PRP store
• The bench command for live mode in helm (optional)

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Read the whole markdown artifact.
2. 2Build the theme : templates/default-theme.css verbatim, then $PRP_DIR/companion.css`
3. 3Read templates/companion.md and follow it exactly.
4. 4Write the page beside the markdown: same directory, final .md replaced by .html
5. 5Before reporting, check the page against the markdown once: every risk, finding, required outcome,
6. 6When the artifact is a review or a plan and command -v bench succeeds, the page is live in helm: read

What it can do on your machine

Read from SKILL.md and the folder at commit 4352925. 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

  Ships script files (JavaScript), which the agent can run.

  Shell commands in SKILL.md call:

  • git

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

  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

PRP Companion Page loads about 990 tokens when it runs. Until then it costs about 158 tokens; SKILL.md has 352 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~158

When it runs · the whole SKILL.md, loaded when a task matches

~990

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

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.

prp-companion

description

Writes the visual HTML companion of a PRP plan or review - one self-contained page beside the markdown that shows a plan's change diagram, steps and risks, or a review's verdict, findings and a diagram of what the PR changed, with every item carrying a stable id a mark can point at. In helm a review or plan page is live: the operator sets each finding's or step's status and replies on the page. prp-plan and prp-review run it after writing their markdown. Use when the user wants to "make it visual", "show me the plan", "visualize this review", "diagram this plan", "write the companion", or invokes /prp-companion.
