A real Codex workflow

Run Agent Immune System, inspect the findings, apply the patch, then compare completion time.

demo/workflow/*

Codex session

Use agent immune system to audit demo/workflow/AGENTS.before.md. Do not edit yet.

Instruction Health Score: 58/100. I found 4 instruction-health issues.

F1 shell rules block safe discovery -> Regenerate

F2 git/worktree rules overlap -> Regenerate

F3 browser proof rules are global -> Demote

F4 every mistake becomes a rule -> Replace

Apply the recommended instruction-health patch.

Applied patch: deleted 16 narrow rules, added 4 durable principles, kept active edits proposal-first.

Show before/after workflow impact.

Demo replay: completion time dropped from 8m20s to 5m00s. Agent interruptions dropped from 5 to 1.

Agent Immune System audit58/100

Finding	Route	Why
Shell rules block read-only discovery	Regenerate	Protection became paralysis
Six git rules repeat one safety goal	Regenerate	Duplicate instruction cluster
Browser proof detail is global	Demote	Belongs in proof workflow
Every mistake becomes permanent	Replace	Creates prompt scar tissue

Patch applied16 rules -> 4 principles

- Never run commands without asking first.

- Always ask before reading files.

- Stop and ask before using rg.

- Always check the branch before editing.

- Always verify git status before editing.

- Stop if the worktree is dirty.

- Never touch unrelated files.

- Always create mobile proof for every visual change.

+ Proceed with safe read-only discovery.

+ Ask before destructive commands, external writes, credential access, or irreversible actions.

+ Before editing, confirm worktree safety: branch, metadata, dirty changes, writer collision.

+ Use browser proof when requested or when frontend changes need acceptance verification.

+ Treat mistakes as evidence, not automatic permanent rules.

Stop adding scar tissue.

Run Agent Immune System before one more failed session becomes a permanent rule.

Use agent immune system to audit my AGENTS.md.

The 40% number is from the included deterministic demo fixture, not a universal performance guarantee.
