trace SKILL.md skillA

trace from zereight/gitlab-mcp is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned

mdr add zereight/gitlab-mcp/trace@git:20260412.9d9ce51

Pins git:20260412.9d9ce51 in mdr.lock. Pin the fingerprint instead.

Evidence-driven tracing with competing hypotheses in parallel. Activate when user says: trace this, trace, why did this happen, root cause analysis, investigate why.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Trace

Evidence-driven causal tracing using competing hypotheses. Use for ambiguous, causal, evidence-heavy questions where the goal is to explain WHY something happened.

## Good Entry Cases
- Runtime bugs and regressions
- Performance / latency behavior
- Architecture / premortem / postmortem analysis
- Config / routing / orchestration behavior
- "Given this output, trace back the likely causes"

## Core Contract
Always preserve: Observation → Hypotheses → Evidence For → Evidence Against → Best Explanation → Critical Unknown → Discriminating Probe

## Workflow
1. Restate the observed result precisely
2. Generate 3 deliberately different hypotheses:
   - Code-path / implementation cause
   - Config / environment / orchestration cause
   - Measurement / artifact / assumption mismatch
3. Assign @tracer to each hypothesis lane
4. Each lane: evidence for, evidence against, critical unknown, discriminating probe
5. Apply lenses: Systems, Premortem, Science
6. Rebuttal round between top two hypotheses
7. Rank, detect convergence, synthesize

## Output
```
### Observed Result
[What happened]

### Ranked Hypotheses
| Rank | Hypothesis | Confidence | Evidence Strength |

How to install

The exact contents, by fingerprint

mdr add zereight/gitlab-mcp/trace@sha256:fb21957a1ad769ff

The line at the top of this page pins the label git:20260412.9d9ce51, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
