description	Read-only investigation workflow using rp-mini context-builder.

rp-investigate

Use this for root-cause analysis, code archaeology, or "how/why is this happening?" questions. This workflow is read-only.

Check workspace binding first. On mismatch, pass root=<absolute path> on every rp-mini tool call. If a shell is available and no MCP client is loaded, use node packages/server/dist/cli.js tool <workspace> <tool> --json-args '...' or its wrappers.

Triage fast path: Bounded question (single subsystem, named symbol, roughly <=5 files) -> answer inline with file_search, read_file, and get_code_structure; do not spawn the builder. Broad, cross-cutting, or durable-context-pack requests -> full builder flow. Both paths keep line-cited evidence.

1. Clarify first: if the symptom, environment, comparison point, or expected behavior is ambiguous, ask with AskUserQuestion before spawning the builder.
2. Record the investigation question, symptoms, hypotheses, and any user-provided evidence.
3. Spawn the context-builder subagent with:
   • task: investigation question plus symptoms and hypotheses
   • budget: default discovery budget unless caller supplied a hard budget
   • response_type: question
   • enhancement mode: rewrite unless the user requested augment or preserve
4. Question loop: this is the rp-build/rp-investigate question loop. If the builder returns <questions> plus a saved profile name, read the cited files, check git history or searches, and answer only conclusive questions with <answer key="..." source="orchestrator" >...</answer>. Escalate with AskUserQuestion only for blocking AND high-stakes questions: irreversible/destructive actions, product policy, money/auth/data-loss. Append <answers> with prompt op=append, resume with manage_selection op=load_profile, and remember advisory questions never interrupt.
5. Pursue evidence from the handoff: read selected files, inspect git history or diffs when relevant, and verify claims with file:line references.
6. Refine selection only when evidence shows the builder missed needed context; bias toward adding, not clearing, selection.
7. Finish with a workspace_context op=export receipt: token totals, content hash, and saved handoff profile. If the caller asked for a durable artifact, write the export to a file with the host Write tool or shell CLI.
8. Report findings as evidence, inference, unknowns, and next recommended action.
