Incident Timeline Reconstruction with Codex: SKILL.md Template
A production playbook for incident timeline reconstruction in cross-industry operations using Codex: skill.md template, run-scoped inputs, logs, typed results, and artifacts.
Audience: SRE and engineering leaders
The problem
SRE and engineering leaders need incident timeline reconstruction to run repeatedly against logs, deploy events, alerts, and chat exports. In cross-industry operations, the pain is not one good answer; it is repeatability, auditability, exception handling, and evidence that survives handoff.
Implementation path
Put the operating procedure in SKILL.md, keep examples beside the skill, attach logs, deploy events, alerts, and chat exports per run, and let Argo turn the folder into a repeatable Codex execution.
Tradeoffs and failure modes
A skill folder is less flexible than an open chat, but it gives the product a versioned workflow that can be tested and rolled back. For incident timeline reconstruction, the practical test is whether a second run can be debugged, retried, and consumed by a product without reading the raw agent transcript.
SKILL.md starter
# SKILL.md
You run incident timeline reconstruction using Codex.
Read only /skill/.argo/inputs.
Write artifacts to /skill/output/artifacts.
Return argo.result.v1 with body.type = "incident_timeline".
Run this on Argo
