boo-mapping-project-context	Produces or refreshes a complete context map of a project: structure, entry points, services, data flow, conventions, dependencies, deploy surface. Use for onboarding into an unfamiliar repo, refreshing stale context docs, "what is this project," "map out the codebase," and pre-work recon before planning. Do NOT use for evaluating architecture quality; use boo-analyzing-architecture. Do NOT use for finding specific bugs; use boo-investigating-failures.

Mapping Project Context

Size

Classify small/medium/large from repo size, number of subsystems, and deployment complexity. Default: small (single-service, single deploy surface). Accept $size override.

Process

1. If the boocontext MCP tools are available (check for boocontext_overview), lead with them: boocontext_overview for routes/schema/components/dependency graph, then boocontext_map for the context map. They produce the structural backbone faster than hand enumeration. Treat their output as codebase-trust evidence (it reads the code), and still verify the verdict envelope (SAFE/CAUTION/UNSAFE) before trusting a result. If the tools are absent, enumerate from disk instead (steps 2-3).
2. Enumerate from disk to fill gaps boocontext does not cover (deploy surface, CI, env/config files, compose): run tree, read package manifests, compose files, configs, and CI files. Trace entry points and service boundaries from code, not from documentation.
3. Read existing context docs (README, CONTEXT.md, wiki) LAST. Diff them against observed reality and flag drift.
4. Small = single-pass (produce the context map directly). Medium/large = dispatch structural-analyst for module graph analysis (seed it with the boocontext dependency graph when available).
5. Output the context map with a "Doc drift" section.

What NOT to do

• Do not produce recommendations. This skill describes; it does not judge.
• Roadmap/changelog files are never valid sole evidence. Every claim cites a file read or executed command.
• Do not read docs before examining the code itself.

Gotchas

• Evidence rule: codebase citations (file:line) stand alone. Roadmap/changelog files are never sole evidence.
• Sizing: default is small. Only escalate on concrete signals - repo size, subsystem count.

• Subagent visibility: when the Paseo MCP tools (mcp__paseo__*) are available, spawn each agent persona as an attached Paseo subagent with create_agent (detached: false, notifyOnFinish: true; for an opencode provider also pass settings.modeId: "build" and settings.features.auto_accept: true) so every persona appears in the operator's Paseo agent track. Resolve each persona's provider/model from the active preset's agents map in ~/.paseo/orchestration-preferences.json; supervise on the finish notification (never poll) and read each result with get_agent_activity.
• Subagent fallback: when the Paseo MCP tools are not available, use the platform's native subagent dispatch. On a platform with no subagent dispatch at all (for example Pi), read each agents/<name>.md persona and apply its lens in sequential passes.
• Subagent concurrency: honor the active preset's concurrency value in ~/.paseo/orchestration-preferences.json. When it is 1 (local heavy-weight presets, around 27b/35b or larger on a single llama-swap server), dispatch subagents STRICTLY ONE AT A TIME: launch one, wait for its finish notification and read its result, then launch the next. This overrides any parallel fan-out. Absent or higher concurrency means parallel fan-out is fine.

• No commit: never commit, push, or stage changes; never git add -A. Prove any edits with git diff --stat.
• No em dashes: never use em dashes (U+2014) in output or files you write.

• Doc drift is a finding: if code contradicts docs, code wins on what the system does today.
• Counts must be fresh: any file or directory count in the report (N skills, N agents, N configs) must come from a command run immediately before writing that line. Counts remembered from earlier in the session produce false drift findings (observed 2026-06-11: a stale glob reported a missing file that existed).
• boocontext is optional, not required: the MCP tools are not registered on every machine or harness. Probe for them; never fail or block when absent, just enumerate from disk. When present, they are an accelerator, not the source of truth: a tool returning UNSAFE or empty means fall back, not stop.
