This template's threat model is unusual: it ships pre-approved Claude Code
permissions (.claude/settings.json) and CLI code that every fork user
executes via those permissions. A plausible-looking PR could therefore
ship risk to every forker: widen a permission to Bash(*), weaken the
personal-data gitignore rules, or smuggle code execution into bun install
via a lifecycle script. Nothing checked for these mechanically.
New job security-guards runs tools/security_guards.py (stdlib only):
- settings.json: every permissions.allow entry must be in an exact,
in-repo allowlist. The guard makes permission changes loud, not
impossible - a PR that intentionally widens permissions must update
the allowlist in the same diff, so the widening is explicit and
reviewable
- .gitignore: the personal-data rules (tracker, documents/**, cv/main_*,
salary data, seen_jobs) must all still be present - the mirror image
of the placeholder-integrity job
- .agents/**/package.json: no lifecycle scripts (preinstall/install/
postinstall/prepare/prepack) and no trustedDependencies, which would
execute arbitrary code during bun install on users' machines
New job dependency-review (PRs only): actions/dependency-review-action
flags newly introduced vulnerable or malicious dependencies,
fail-on-severity high.
Workflow hardening: explicit top-level permissions: contents: read
(least-privilege token), and all actions pinned to commit SHAs resolved
from the same major tags already in use (checkout v4, setup-python v5,
setup-bun v2), with the tag recorded in a comment.
Honest limit, recorded in the workflow header: a PR can edit this
workflow itself, so these guards catch accidents and casual attempts,
not a determined author. Branch protection with required checks and
human review of workflow/settings diffs remain the real backstop.
Verified locally: positive run passes; injecting Bash(*) into
settings.json, deleting the tracker gitignore rule, and adding a
postinstall script each fail the guard with the intended message, and
reverting restores a clean pass.
