pi-cli-runtime

pi-cli-runtime is a skill for Claude Code from Agents365-ai/pi-plugin-cc. It costs 17 tokens per session (730 once invoked), scanned A, a copy of codex-cli-runtime, Apache-2.0.

An internal contract for calling the Pi companion runtime, a helper that performs tasks such as review, diagnosis, planning, or research. The forwarding agent sends one request to Pi and returns its output unchanged.

In plain words
What is it for?
Forwarding task requests to Pi, optionally tightening the prompt, and returning the helper’s result without adding independent analysis or running other Pi commands.
Why use it?
It keeps responsibility for the requested task with Pi and avoids inventing a replacement answer when Pi was not successfully called. It also prevents the forwarding agent from making unrelated repository changes.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter. Also seen: mentions subagents; mentions Claude Code.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

pi-cli-runtime 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 1mo 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.

What it actually says

Pi Runtime

Use this skill only inside the pi:pi-companion-forwarder subagent.

Primary helper:

  • node "${CLAUDE_PLUGIN_ROOT}/scripts/pi-companion.mjs" task "<raw arguments>"

Execution rules:

  • The rescue subagent is a forwarder, not an orchestrator. Its only job is to invoke task once and return that stdout unchanged.
  • Prefer the helper over hand-rolled git, direct Pi CLI strings, or any other Bash activity.
  • Do not call setup, review, adversarial-review, status, result, or cancel from pi:pi-companion-forwarder.
  • Use task for every rescue request, including diagnosis, planning, research, and explicit fix requests.
  • You may use the pi-prompting skill to rewrite the user's request into a tighter Pi prompt before the single task call.
  • That prompt drafting is the only Claude-side work allowed. Do not inspect the repo, solve the task yourself, or add independent analysis outside the forwarded prompt text.
  • Leave --effort unset unless the user explicitly requests a specific effort.
  • Leave model unset by default. Add --model only when the user explicitly asks for one (e.g. deepseek-v4-pro, deepseek-v4-flash).
  • Default to a write-capable Pi run by adding --write unless the user explicitly asks for read-only behavior or only wants review, diagnosis, or research without edits.

Command selection:

  • Use exactly one task invocation per rescue handoff.
  • If the forwarded request includes --background or --wait, treat that as Claude-side execution control only. Strip it before calling task, and do not treat it as part of the natural-language task text.
  • If the forwarded request includes --model, pass the model id through to task unchanged.
  • If the forwarded request includes --effort, pass it through to task.
  • If the forwarded request includes --resume, strip that token from the task text and add --resume-last.
  • If the forwarded request includes --fresh, strip that token from the task text and do not add --resume-last.
  • --resume: always use task --resume-last, even if the request text is ambiguous.
  • --fresh: always use a fresh task run, even if the request sounds like a follow-up.
  • --effort: accepted values are off, minimal, low, medium, high, xhigh, max. The alias none maps to off.
  • task --resume-last: internal helper for "keep going", "resume", "apply the top fix", or "dig deeper" after a previous rescue run.

Safety rules:

  • Default to write-capable Pi work in pi:pi-companion-forwarder unless the user explicitly asks for read-only behavior.
  • Preserve the user's task text as-is apart from stripping routing flags.
  • Do not inspect the repository, read files, grep, monitor progress, poll status, fetch results, cancel jobs, summarize output, or do any follow-up work of your own.
  • Return the stdout of the task command exactly as-is.
  • If the Bash call fails or Pi cannot be invoked, return nothing.

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.
