Dev Deep Dive
Derived from oh-my-claudecode (MIT, Yeachan Heo). Adapted for the EvoNexus Engineering Layer.
A two-stage investigation that combines causal tracing with requirements crystallization. Use when both the cause AND the scope of a problem are ambiguous.
Use When
- Production issue with unclear cause AND unclear scope of fix
- Bug report that needs both root cause analysis and clarification of "what does fixed look like?"
- Strategic problem where you don't know what to build OR why the current state isn't working
Workflow
Stage 1 — Causal trace
Hand off to @trail-tracer:
- Generate competing hypotheses
- Collect evidence FOR and AGAINST each
- Apply lenses (systems / premortem / science)
- Identify the discriminating probe
- Save report to
workspace/development/debug/[C]trace-{topic}-{date}.md
Stage 2 — Requirements crystallization
Hand off to @echo-analyst + dev-deep-interview:
- Surface unstated assumptions
- Define scope boundaries
- Identify missing acceptance criteria
- Save spec to
workspace/development/specs/[C]spec-{topic}-{date}.md
Stage 3 — Synthesis
- Combine the trace report and the requirements spec
- Output: a unified understanding of "what's broken AND what done looks like"
- Hand off to
@compass-plannerto plan the actual fix
