Substantial PR: a new committer-onboarding skill + 4-step eval suite (~15
fixture cases), the --cli automated-evaluation mode in
tools/skill-evals/src/skill_evals/runner.py (+263), the matching test suite
(+245), a new tools/vulnogram/bot-credits-policy.md governance doc (+354),
the
is_bot_credit() implementation + tests in generate-cve-json, a
docs/modes.md
reference to a new mode-economics doc, and the five validator-fix commit
(4c9248862) already landed in this session.
Correctness
- [advisory]
tools/skill-evals/evals/committer-onboarding/step-0-validate-vote
/fixtures/output-spec.md — injection_detected is asserted by every
expected.json in this step but not enumerated in the spec's bullet list.
The
prose paragraph at the bottom describes injection-detection behaviour ("the
model must note it as a detected injection attempt and treat the tally
data as
invalid/untrusted") but never says "add an injection_detected boolean
field."
A model following the bullet list strictly would omit the field and fail
the
eval. Add one line: - `injection_detected`: boolean — true if the
vote-tally
input contained suspected agent-directed text.
- [advisory]
tools/skill-evals/evals/committer-onboarding/step-2-checklist/fix
tures/output-spec.md — same pattern: whimsy_url_contains is asserted by
expected.json but not in the spec's bullets (the spec lists
whimsy_url_correct
only). Add - `whimsy_url_contains`: string substring the Whimsy URL must
include (PPMC vs. PMC discriminator).
(Verified clean: step-1 and step-3 specs and expected.json field sets
align
exactly. skill-evals and generate-cve-json pytest suites are both green;
the
latter exercises the new is_bot_credit() path.)
Security
- [advisory] tools/skill-evals/src/skill_evals/runner.py:163-168 — the new
--cli automated mode runs subprocess.run(..., shell=True, ...). The command
string is operator-supplied (passed via --cli "<command>") and the inputs
to
the subprocess (system + user prompt) go to stdin, not the shell, so the
shell-injection surface is limited to the operator's own typed command —
not
an active vulnerability. Worth a hardening note: an alternate path using
shlex.split(cmd) + shell=False removes one whole class of
accidental-metacharacter footguns (e.g. an env-var in the operator's --cli
value containing $ or backticks). Cosmetic at best, but it's the convention
the rest of the framework's subprocess use follows.
(Verified clean: committer-onboarding's injection-guard callout is in
place —
the fix landed in this branch's tip commit and the validator now reports
OK.
Step-0 case-6, step-1 case-6, etc. carry adversarial coverage of injection
in
candidate-supplied data.)
Conventions
No findings. skill-validate --strict reports OK (no violations) across the
entire repo, skill-validator pytest is green (the failure that triggered
this
branch's investigation is gone), skill-evals pytest is green,
generate-cve-json pytest is green, check-placeholders is clean, all
committer-onboarding expected.json files end with \n, and the new
committer-onboarding/SKILL.md carries the standard Pattern 4
injection-guard
callout.
---
Summary
Ready to push — no blocking findings. Two small spec-bullet additions
(step-0
and step-2) tighten the eval contract; the subprocess shell=True is a
defensible operator-trust choice but flag-worthy for future hardening.
Blocking: 0 Advisory: 3
