By name: greedy-search description: Web/search plus opt-in research via Perplexity, Google AI, ChatGPT, Gemini, Semantic Scholar, and Logically. Grounded all-engine search fetches sources by default; optional configurable synthesis; deep research as separate workflow. Configurable via ~/.pi/greedyconfig. Bing Copilot available for signed-in users. Current docs, recent changes, dependency choices. NOT codebase search.
greedy_search({ query, engine: "all"|"perplexity"|"google"|"chatgpt"|"gemini"|"semantic-scholar"|"logically"|"bing", synthesize?: bool, synthesizer?: "gemini"|"chatgpt", depth?: "research", breadth: 1-5, iterations: 1-3, maxSources: 3-12, researchOutDir?: string, writeResearchBundle?: bool, visible: bool })
Modes: individual engine search · grounded engine:"all" search with fetched sources · optional synthesize:true using the configured synthesizer over all-engine results · depth:"research" for the iterative deep-research workflow.
Config: ~/.pi/greedyconfig supports { "engines": ["perplexity", "google", "chatgpt", "gemini", "semantic-scholar", "logically"], "synthesizer": "gemini" }. Gemini is a normal search engine; Semantic Scholar and Logically are opt-in research engines. Any configured engine can participate in engine:"all"; deep research child searches reuse the same configured engines list and stdin-safe query passing. Normal all-search synthesis remains controlled separately by synthesizer; research planning/final synthesis uses Gemini.
Compatibility: legacy depth:"fast"|"standard"|"deep" is still accepted. fast skips source fetching; standard/deep alias synthesize:true. Prefer synthesize:true, optional synthesizer, and depth:"research" going forward.
Research output: depth:"research" writes a dataroom-style bundle by default under .pi/greedysearch-research/<timestamp>_<query>/ with STATUS.md, OUTLINE.md, reports/SUMMARY.md, reports/CLAIMS.md, reports/GAPS.md, sources/, and data/manifest.json. Pass researchOutDir to choose the directory or writeResearchBundle:false to disable disk output.
Auto-recovery: Headless default. Bing/Perplexity auto-retry visible on CF block. Manual CAPTCHA → visible stays open; solve then rerun.
CDP safety: Use bin/cdp-greedy.mjs only. Never raw bin/cdp.mjs.
