Unblocked Context Research

Unified context retrieval via contextresearch. Searches PRs, docs, messaging platforms, issue trackers, and code history to surface WHY code works the way it does, what was tried before, and what constraints apply. TRIGGER when: you need decision history, prior art, or conventions before modifying code; planning, scoping, or researching a topic; investigating a bug or incident; you need filtered lookups across issues, messages, or PRs (e.g., "open bugs in PROJECT", "what did X work on last week"); Grep/Glob/Read failed to find the referenced code — this skill searches across repos and systems beyond the current workspace. DO NOT TRIGGER when: you only need current implementation (not history or reasoning) — use Grep/Glob/Read directly.
