XPI

Security tooling for the Pi agent — casefile tracking, web search, exploit-technique intelligence, code search, and todos.

What it is

XPI turns the Pi agent into a security researcher: a case ledger with enforced gates, real exploit-technique grounding, web lookup, fast code search, and a pipeline that keeps findings honest.

• Casefile — hypothesis → investigating → confirmed → reported, with gates at every step
• Machine-owned PoC gates — zero exit is necessary but never proof: direct-response findings require nonce-bound body evidence plus a DNS-pinned, conclusive target_only replay against an operator-approved control; reflection-capable requests can add a harness-generated target-only canary; only the main agent may make the semantic decision and commit phase 2
• Exploit chains — ChainSuggest surfaces combinations the model missed
• Coverage matrix — machine-checkable "we tested everything" claims
• Code search — structural AST search (ast-grep) for sinks and call chains, plus built-in grep/find for text

Install

Works on Pi Agent and its fork OMP (@oh-my-pi/pi-coding-agent). One manifest serves both: OMP reads the same pi extension field, the Agent Plugins plugin.json for skills, and the task tool spawns the specialist agents.

./install.sh            # auto-detects pi or omp in PATH
./install.sh --pi       # force Pi  (installs pi-subagents + optional ast-grep structural search)
./install.sh --pi --no-subagents  # minimal Pi install; use /xp lite because swarm dispatch is unavailable
./install.sh --omp      # force OMP (copies agents/*.md to ~/.omp/agent/agents)

Or install the npm package per host:

pi install npm:@xaccefy/pi-xpi     # Pi
omp install npm:@xaccefy/pi-xpi    # OMP

Set PREVIEW_IS_API_KEY for exploit_search (see docs/guide.md).

Quick start

/xp        # toggle bounded swarm XP mode on/off
/xp lite   # explicit single-agent security workflow
/xp swarm  # bounded multi-agent pipeline

Use /xp for the default bounded swarm workflow, or /xp lite for CTFs, focused reviews, and one-target work where dispatch is unnecessary. On Pi, swarm dispatches only auditor, tracer, skeptic, and chain via pi-subagents; on OMP it uses the native task tool with the same four agent names. Validation, patching, reporting, and ConfirmFinding stay with the main agent.
