XPI

Security tools for Pi Agent: casefile tracking, web search, library docs, exploit technique search, code intelligence, and todos.

Install

Automate XPI plus third-party extension deps (pi-codex-goal, pi-mcp-adapter):

./install.sh

Or:

pi install npm:@xaccefy/pi-xpi

API keys / env

Variable	Package	Purpose
PREVIEW_IS_API_KEY	webxp	Required for exploit_search (preview.is)
PI_XP_MODE	casefile	on / off — force casefile cyber-workflow injection
PI_CASEFILE_PATH	casefile	Override SQLite ledger path
PI_WEBSEARCH_PORT	webxp	open-websearch daemon port (default 3210)
PI_CHROMIUM_PATH	webxp	Chromium binary for SPA re-render in web_fetch

export PREVIEW_IS_API_KEY="rk_yourkeyhere"

Tools

Tool	Use for
exploit_search	Attack techniques, primitives, bypasses (PREVIEW_IS_API_KEY)
web_search	CVEs, advisories, documentation
web_fetch	Page content; SPA pages re-rendered via Chromium when the shell is thin
context7	Current library docs
deepwiki	Q&A on a public GitHub repo
CaseAdd / CaseUpdate / PromoteFinding	Ledger + hard PoC gate to confirm
CaseGet / CaseList / CaseSearch	Browse cases
CaseLink / CaseUnlink	Exploit chains
CaseReport	Markdown report
/casefile	Case dashboard
/xp	Toggle casefile XP mode (cyber workflow injection; default OFF)
todo / /todos	Multi-step task lists
fff (ffgrep / fffind)	Frecency-ranked file + content search; in override mode transparently upgrades pi's built-in grep/find. Installed by install.sh.

Quick start

/xp on                                      # enable casefile cyber workflow in context

Skills (skills/web-pentest, skills/pipeline) auto-load into agent context. No slash commands needed for methodology — just tell the agent what to hunt. Run /xp on for the full attacker discipline with casefile tracking.

Code search (fff)

XPI uses fff (@ff-labs/pi-fff) for file and content search. It's a frecency-ranked, typo-tolerant search engine that runs as a native Pi extension — no separate MCP process.

install.sh installs it and sets PI_FFF_MODE=override, which transparently replaces pi's built-in grep/find/multi_grep with fff's implementations. The agent's existing grep/find calls become faster and smarter with no prompt or skill changes — ffgrep auto-detects regex vs fuzzy, fffind matches whole repo-relative paths and ranks by frecency.

For a target repo, the auditor and tracer agents use grep/find/read to locate sinks, entry points, and call chains — fff makes those searches accurate across large codebases without a heavy index step.

Develop / release

bun install
bun test --isolate
bun run typecheck

Release (CI): GitHub Actions → Release workflow → choose patch / minor / major.
Requires repo secret NPM_TOKEN. The job runs tests, bumps all workspace versions, publishes every package + umbrella, tags vX.Y.Z, and pushes.

Local release helper:

bun run release:patch   # or release:minor / release:major

(Requires a clean tree, npm auth, and push rights.)
