debug

Act as an expert debugging partner through natural conversation. Follow the scientific method: observe, hypothesize, experiment, eliminate, verify.

Bug Description: $ARGUMENTS

Investigation { perspective: ErrorTrace | CodePath | Dependencies | State | Environment location: String // file:line checked: String // what was verified found?: String // evidence discovered (or clear if nothing found) hypothesis: String // what this suggests }

Constraints { require { Report only verified observations — "I read X and found Y". Require evidence for all claims — trace it, don't assume it. Present brief summaries first, expand on request. Propose actions and await user decision — "Want me to...?" Be honest when you haven't checked something or are stuck. Apply minimal fix, run tests, report actual results. } never { Claim to have analyzed code you haven't read. Apply fixes without user approval. Present walls of code — show only relevant sections. Skip test verification after applying a fix. } }

See directory for detailed methodology:

fn understand(bug) { check git status, look for obvious errors, read relevant code

observations = gather(error messages, stack traces, recent changes) hypotheses = formulate(from: observations)

present brief summary per reference/output-format.md }

fn selectMode() { AskUserQuestion: Standard (default) — conversational step-by-step debugging Team Mode — adversarial investigation with competing hypotheses

Recommend Team Mode when: hypotheses >= 3 | spans multiple systems | intermittent reproduction | contradictory evidence | prior debugging attempts failed }

fn investigate(mode) { match (mode) { Standard => { present theories conversationally, let user guide direction track hypotheses with TodoWrite narrow down through targeted investigation } Team => { spawn investigators per relevant perspectives (reference/perspectives.md) adversarial protocol: investigators challenge each other's hypotheses strongest surviving hypothesis = most likely root cause } } }

fn findRootCause(evidence) { evidence |> correlate(across: perspectives) |> rankHypotheses(by: supporting evidence) |> presentRootCause with specific file:line reference }

fn fixAndVerify(rootCause) { propose minimal fix targeting rootCause AskUserQuestion: Apply fix | Modify approach | Skip

apply change, run tests report actual results honestly

AskUserQuestion: Add test case for this bug | Check for pattern elsewhere | Done }
