Use to audit Brain execution hygiene: loose captures, raw/source gaps, outputs without tasks, and tasks stuck in review.
Install with Codex or Claude Copy this prompt, paste it into Codex, Claude, or another assistant, and let it review the skill page and install it for you.
Based on SOC occupation classification
Never re-fight a settled battle. Discipline for recording and RETRIEVING past failures — gotchas, incidents, postmortems, dead ends, reverted fixes — as symptom → root cause → evidence → status. Use before debugging anything that smells familiar, when an incident closes, when a fix gets reverted, when an approach is abandoned, or when asked to document a bug just solved, write a postmortem, do failure archaeology, incident memory, or "did we hit this before". Not for capturing general knowledge (use brain_capture / brain_write) or live task tracking.
Write research prompts that come back decision-ready — zero-prior-knowledge framing, evidence hierarchy, fact/inference separation, and a mandatory gap round. Use when formulating a research prompt, deep research request, competitive research, market research, due diligence question, or when delegating research to exa_search, an agent, Codex, or an external researcher. Not for running the research itself end-to-end (deep-research, autoresearch, gemini-deep-research, exa_search EXECUTE research — this skill writes the brief that feeds them), not for the reference deployment strategic deliberation (use council/punta-de-flecha), and not for Brain lookups (brain_search first, always).
Transfer full working context to a fresh agent session with zero memory — end of session, before compaction, switching models/agents mid-project, or pausing multi-day work. Use when asked for a handoff, handoff doc, session transfer, "deja esto listo para la próxima sesión", context dump for another agent, or when a long session is about to hit context limits. Not for delegating a bounded task (use codex-handoff) or for task cards (use handoff-task / brain_task tools).
Evaluate whether a the reference deployment skill actually works — blind runner + separate judge against a bar, rubric scoring, pass-rate on re-runs, and defect diagnosis. Use when asked to evaluate a skill, eval skills, run a blind eval, score against a rubric, test a skill, audit skill quality, grade a skill, review the skill library, or before promoting a new skill to the company master prompt or the whole swarm. Not for writing skills (use skill-authoring-standards) or deciding which to create (use suggest-skills).
Turn a big or ambiguous technical task into a spec of independently verifiable slices, implement slice-by-slice with verification gates, and close the spec with a claim audit. Use when asked to write a spec, implement a spec, plan a build, break down a feature, structure a multi-day or multi-week technical project or migration, or when a Codex/agent delegation is too big for one self-contained prompt. Not for small tasks (single codex-handoff prompt suffices) or non-technical plans.
Verify visual work with evidence instead of vibes — screenshot critique by a fresh judge, before/after comparison, crops of the disputed detail, and a distance-not-verdict mindset. Use when reviewing a UI, landing, email template, dashboard, canvas, or design change; when doing a screenshot critique, comparing screenshots, doing visual QA or UI QA on a landing page, checking a clone against a reference, or before declaring any visual deliverable done. Not for choosing a design direction or running a dedicated accessibility audit.

Public, anonymized version of a skill running in the Compai reference deployment (an 8-figure consumer SME). Names, stores, channels and endpoints replaced with placeholders; the logic is unchanged. Adapt to your own context.
Use this skill before/after Brain v2 ingestion or weekly digest work.
