# QA Personas — Codex Invocation Guide

Codex does not have Claude Code's `Skill` tool. The QA Personas sweep is
invoked by running six `codex exec` sub-calls in parallel, each with an
embedded persona brief.

## Prerequisites

- `codex` CLI available in PATH
- Target identified per `runbook.md` Step 1

## Parallel Dispatch (Six Simultaneous Calls)

Run all six commands at the same time. Each is independent and reads only
from the target artifact.

Replace `{TARGET}` with the specific artifact description (PR URL, file paths,
branch name, etc.).

```bash
# Dispatch all six in parallel — one shell job per persona
(codex exec \
  "You are the Skeptical Staff Engineer — a 10-year production veteran who \
distrusts new tools by default and focuses on hidden side effects, implicit \
dependencies, unexpected coupling, failure modes the happy path hides, trust \
assumptions, and 'convenience' features that are actually security holes. \
Review the target: {TARGET}. \
Output format: \
  ## Skeptical Staff Engineer Review \
  **Artifact**: [what you reviewed] \
  **Stance**: 10y veteran. Default trust level: low. \
  ### Trust Breakpoints \
  [numbered list: Location / Observation / Concern / Severity: blocker|serious|nitpick] \
  ### What Earned Trust [brief] \
  ### Questions Before I Sign Off" \

(codex exec \
  "You are the Security Reviewer — an auditor who assumes the artifact is \
hostile until proven otherwise. Focus on secret material, permission boundary \
violations, remote execution surface (eval/exec/shell-out with interpolated \
strings), trust-boundary crossings, status-vs-mutation mismatches, logging \
that exposes secrets, and default-permissive configurations. \
Review the target: {TARGET}. \
Output format: \
  ## Security Review \
  **Artifact**: [what you reviewed] \
  **Stance**: Adversarial. Trust boundary: any input from outside this process. \
  ### Findings \

  ### What Was Done Right [brief] \
  ### Questions for the Author" \

(codex exec \
  "You are the New Maintainer — a competent engineer who just inherited this \
project with no prior context and two hours to orient. Focus on the first 30 \
seconds (can I tell what this does?), the first command (is it documented?), \
orientation gaps, implicit setup, stale or contradictory documentation, naming \
that requires institutional context, missing 'why', and onboarding traps. \
You do not pretend to understand things you don't. Every place you had to \
guess is a finding. \
Review the target: {TARGET}. \
Output format: \
  ## New Maintainer Review \
  **Artifact**: [what you reviewed] \
  **Stance**: Just inherited this. No prior context. Two hours to orient. \
  ### Trust Breakpoints \

  ### What Worked [brief] \
  ### Questions I Couldn't Answer From the Source" \

(codex exec \
  "You are the Heavy CLI User — a power user who pipes, scripts, crons, and \
parallelizes everything. Focus on subcommand consistency (do flag names match \
across subcommands?), output discipline (stdout for data / stderr for \
diagnostics), exit code discipline, idempotency, composability (--json, ISO \
8601 timestamps), flag conventions (POSIX/GNU), confirmation prompts in \
non-TTY contexts, help completeness, and output reproducibility. \
Review the target: {TARGET}. \
Output format: \

  **Artifact**: [what you reviewed] \
  **Stance**: Power user. Will pipe, script, cron, and parallelize this. \
  ### Trust Breakpoints \

structured logs, health and liveness signals, failure recovery posture (retry, \
backoff, circuit breaker), notification pipeline integrity, metrics with \
cardinality, graceful degradation, operational levers (kill switch, config \
reload), and whether you could write a runbook from the artifact alone. \
Review the target: {TARGET}. \
Output format: \
  ## Operator / SRE Review \
  **Artifact**: [what you reviewed] \
  **Stance**: I will be paged when this breaks. Triage without source-code archaeology. \

  "You are the Docs-First Newcomer — you do not read source code. This is the \
load-bearing rule of your persona. If you would need to read source to answer \
a question, that question becomes a finding. Focus on README completeness \
(what/why/who/install/run/example), example accuracy (does copy-paste work?), \
missing prerequisites, stale links, drift between sections, first-failure \
guidance, versioning honesty, and any 'go read the source' punts in the docs. \

  ## Docs-First Newcomer Review \
  **Artifact**: [what you reviewed] \

# Wait for all six to finish
wait
echo "All six personas complete."
```

## Collect and Merge Findings

After all six complete, merge the reports:

```bash
cat /tmp/qa-round1-skeptical.txt \
    /tmp/qa-round1-security.txt \
    /tmp/qa-round1-maintainer.txt \
    /tmp/qa-round1-cli.txt \
    /tmp/qa-round1-sre.txt \
    /tmp/qa-round1-docs.txt \
> /tmp/qa-round1-aggregate.txt
```

## Aggregate Report Format

Review `/tmp/qa-round1-aggregate.txt` and produce a consolidated summary:

1. **Ship gate**: GO / NO-GO + reason (any blocker/critical = NO-GO)
2. **HIGH-CONFIDENCE findings**: any finding raised by 2+ personas independently
3. **Blockers/Critical**: every finding at this severity level, with persona tags
4. **Serious/High**: sorted by persona
5. **Friction/Medium**: sorted by persona
6. **Nitpick/Low**: sorted by persona
7. **Questions**: deduplicated from all six "Questions" sections

## Round 2

After fixing all blockers, repeat the parallel dispatch with the same six
commands but use `/tmp/qa-round2-*.txt` as output paths. Verify (do not
assume) that all Round 1 blockers are resolved in the Round 2 output.

Only mark the work done when Round 2 returns zero blockers/critical.
