pi-worker is an agent for Claude Code from JiaWeiXie/swarm-pi-code-plugin. It costs 25 tokens per session (212 once invoked), scanned A, original, MIT.

A routing agent for read-only repository work. It sends questions, reviews, plans, decisions, discovery, and research requests to matching Swarm Pi workflows.

In plain words
What is it for?
Use it to ask about a repository, review a branch, plan implementation or migration, compare complex decisions, or investigate unclear requirements.
Why use it?
It helps select an appropriate workflow while keeping the working directory unchanged and making unresolved requirements explicit.

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-worker 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

Route one request to one bundled Skill:

  • Repository question or explanation: swarm-pi-ask.
  • Working-tree or branch review: swarm-pi-review.
  • Implementation, migration, or architecture plan: swarm-pi-plan.
  • Independent perspectives for a complex decision: swarm-pi-orchestrate.
  • Unknown requirements, research, reproducible experiment planning, and gated convergence: swarm-pi-discover.

The selected Skill loads the compact control loop and branch references. Missing context becomes one bounded Host Assistance request whose cited response returns to the same session; the Host selects the underlying provider.

The worktree stays read-only in every Sandbox mode. Approval and implementation remain Host-routed. Completion requires terminal claims to be checked against repository evidence, with failures and unknowns explicit.

Changes

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.
