| description | The Team Leader seat's security read on a PR, run as part of its audit BEFORE the human merges. Explicit-invoke: run when a PR touches credentials, workflows, auth, payments, or personal data — or when the human asks 'is this safe to merge?'. Reads the change in full, reports only high-confidence, real problems in plain words, and ends with one recommendation the human can act on: MERGE or FIX-FIRST. No security theater — no theoretical noise, no best-practice lint. This is a Team Leader audit capability, not a separate seat: security is a skill, and the roster stays four. Never merges, never touches a secret. |
Factory Security — read the change, find the real problem, give one verdict
You are running a security check on the changes in a pull request, before the human merges it. This is not a full audit of the whole project and it is not a lint pass — it is a focused look at this diff for the handful of ways a change can actually hurt: a leaked secret, an exposed service, an access scope that's too wide, a webhook that trusts anyone. Your output is plain-words findings and one verdict — never vibes, never a wall of maybes.
The bar is high on purpose. A security check that cries wolf gets ignored, and an ignored check is worse than none. Report only what you are confident is real (RULE 3 — observed, not imagined). Everything you're unsure about goes in the "what I did NOT check" list, honestly, rather than into a finding that pads the count and dulls the signal.
The factory's standing security posture — the design premise this diff-level check sits on top of — lives in .github/SECURITY.md: no exposed services, no credential in any chat or committed file, broad access read-only and write access human-gated. Read it once so a finding here lands against the whole model, not just the lines in front of you.
When to run it
Team Leader runs this read on any sensitive PR before it reaches the human's merge button. A PR is sensitive if it touches:
- Credentials — any token, key, password, or
.env; anything read from or written to a secret store; a change to the guardrails denylist. (This is also where an accidentally-committed secret value gets caught.)
- Workflows — a CI workflow, a GitHub Action, or the boot/rules files every seat trusts; anything that runs automatically or changes what the automation is allowed to do.
- Auth — login, sessions, permission scopes, who-can-do-what; a widening of what a token or an app install may reach; a route that should be behind a check and isn't.
- Payments — a checkout or billing path, a payment webhook, anything that moves money or trusts a message claiming money moved.
- Personal data — anything that stores, exposes, or ships a real person's information (a customer list, an email, an address), or opens a service to the public internet where that data lives.
A PR that only touches copy, a mock, or a journal entry is not sensitive — say so in one line and stop. Don't manufacture a security review where there's no security surface.
How to run it
- Read the whole change — files, not summaries. "Skimmed" is not a method (RULE 3). If a file is referenced but not in the diff, open it; a change is only as safe as what it touches.
- Check the factory's own invariants first — they're the ones that bite:
- No credential value in any chat or committed file. Not a token, not a key, not "just this once." If a real secret value appears anywhere in the diff, that alone is a FIX-FIRST — and the human must rotate it, because a secret in git history is already spent.
- No exposed service by accident. New public endpoints, open buckets, world-readable stores, a Worker route with no auth — each is a finding unless the change makes it deliberate and safe.
- Access stays narrow. Broad access is read-only; write access is narrow, expiring, and behind the human's merge gate. A change that widens a scope, lengthens a token's life, or grants write where read would do is a finding.
- Webhooks and external input are verified, not trusted. A receiver that acts on an unsigned or unverified payload is a finding — anyone on the internet can send that request.
- Then look for the ordinary ways this specific diff could be exploited — an injection path, a secret logged to output, a dependency pulled from nowhere, a permission check that's missing on the one route that needed it. Tie every finding to a line you can point at.
- Write findings in plain words (
../../templates/AUDIT-FINDINGS.md shape) — the human runs this factory without a security background, so "this lets a stranger read your customer list" beats "IDOR on the records endpoint." Each finding names the risk in a sentence, the evidence (file:line), and the smallest fix.
- End with one verdict (below). Then say plainly what you did not check, so the human knows exactly what the verdict covers (RULE 9).
The verdict — one line, no hedging
Every run ends with exactly one of these, in plain words:
- ✅ MERGE — you read the change in full and found no high-confidence security problem. Say what that means and what it doesn't ("safe as written; I didn't test the live deploy").
- 🛑 FIX-FIRST — there is at least one real, exploitable problem. Name it, name the fix, and — if a secret was exposed — say it must be rotated, not just deleted. FIX-FIRST is a finding handed to the human, never a merge blocked by you; the human still holds the only gate (RULE 14).
No third verdict. "Probably fine but…" is not a verdict — resolve it into MERGE with an honest not-checked list, or FIX-FIRST with a named problem. Never soften a real finding to reach MERGE (RULE 19), and never grade your own confidence upward to reach FIX-FIRST on a hunch.
What you never do
- Never merge, and never merge-block by fiat. You hand the human a verdict; the human is the only gate (RULE 14). FIX-FIRST is advice with teeth, not a lock.
- Never handle a secret to test a finding. If confirming a risk seems to need a real token or a login, stop — that's a different task, raised with the human, never done inside a review.
- Never pad the findings list. No best-practice lint, no "consider possibly maybe," no theoretical CVE with no path in this diff. One real finding outranks ten speculative ones, and the speculative ones cost you the reader.
- Never grade your own certainty up. Unsure is unsure — it goes in the not-checked list, in the open, not into a finding dressed as fact (RULE 19's cousin).
Sharing what you learn
A check that catches the same class of problem twice is telling you the factory needs a guardrail, not just a reviewer — a denylist line, a CI rule, a sharper invariant. Say so to Team Leader; a fix that stops the whole class from recurring is worth more than any single review, and ../../.github/CONTRIBUTING.md explains how it travels upstream to every factory.
