Execute this skill to explore and understand how a codebase works, using Git to efficiently track changes between explorations.
When invoked, you will:
Before executing any step, verify all required skills are present:
[skills-root]/context/SKILL.md
[skills-root]/preflight/SKILL.md
[skills-root]/domain-registry/README.mdWhere [skills-root] is the parent of this skill's directory. Resolve with ls ../ from this skill's location.
If any required file is missing → stop immediately and output:
⚠ Missing required skills for deep-explorer:
{missing-skill}
Expected: {skills-root}/{missing-skill}/SKILL.md
Install the missing skill(s):
git clone https://github.com/mikeng-io/agent-skills /tmp/agent-skills
cp -r /tmp/agent-skills/skills/{missing-skill} {skills-root}/
Or install the full suite at once:
cp -r /tmp/agent-skills/skills/ {skills-root}/All dependencies present → proceed to Step 0.
Context (always required):
Invoke Skill("context") first. It identifies what to explore, confirms artifact type, and establishes domain focus:
context_report:
artifact_type: "" # code | financial | marketing | creative | research | mixed
domains: [] # matched domain names from domain-registry
routing: "" # routing recommendation (informational for explorer)
confidence: "" # high | medium | lowPreflight (conditional — triggered by context confidence):
Invoke Skill("preflight") only if context_report.confidence == "low" OR one or more signals remain unresolved:
Preflight fills exactly the gaps context could not resolve (max 3 questions, one at a time):
scope_clarification:
artifact: "" # repository or directory to explore
intent: "explore"
domains: [] # focus domains for exploration (supplements context_report.domains)
constraints: [] # specific areas to prioritize or exclude
confidence: "" # high | mediumIf context_report.confidence == "high" → skip preflight entirely.
Merge into working scope:
working_scope:
artifact: "" # repository or directory to explore
domains: [] # from context_report, supplemented by preflight
constraints: [] # areas to prioritize or exclude
context_summary: "" # combined description for explorer agent promptsUse working_scope to focus exploration agents on relevant domains and files.

### API Layer
**Status:** ⚠️ Partially stable (mixed committed/uncommitted)
**What Changed:** Rate limiting + new endpoints
**Stable (Committed):**

- Configuration complete
**Unstable (Uncommitted):**
- New endpoints not yet committed
- Error handling still being refined

3. ✅ Verify legacy auth removal is complete
4. ✅ Update API documentation
**For Uncommitted Changes:**
1. ⚠️ Complete src/api/routes.ts integration
2. ⚠️ Add src/utils/helpers.ts to Git
3. ⚠️ Commit or stash work in progress
4. ⚠️ Run tests before committing
