secret-scrub.js (the opencode bash guard) was missing three rules the Claude
bash-guard hook has, leaving a Grok dev able to read secrets the Claude path
blocks:
- source / dot-source of a credential-bearing file (source .env, . ./.env,
.bashrc / .git-credentials / .netrc / /proc/*/environ).
- interpreter one-liner reading a credential file
(python -c "open('.env')", node -e "readFileSync('.git-credentials')").
- git-ops check now runs on a SKELETONIZED command (heredoc bodies + echo/printf
args stripped) so a README/heredoc that merely documents `git push` is no
longer mistaken for invoking it — a false-positive parity fix from the Claude
guard.
Functionally smoke-tested with node against the real plugin (git push denied;
echo/heredoc "git push" allowed; source/interpreter cred reads denied; normal
commands allowed). Live opencode firing stays flagged in the file header.
- pricing.py: add grok-build-0.1 rates ($1/1M input, $0.20 cached, $2/1M
output), verified against xAI's published pricing. Grok is a priced
non-Anthropic model, so cost computes the moment usage is captured.
- secret-scrub.js: an opencode tool.execute.before plugin porting the
security-critical bash-guard deny rules (git network ops, credential-file
reads, /proc env, internal-host HTTP, roboco.* imports, ROBOCO_AGENT_ID
forgery, env dumps, destructive rm) to the opencode runtime — restoring the
guard the Claude Code hook can't provide there. Throwing denies the call
(confirmed by opencode's env-protection example). Wired into the generated
opencode.json plugin array + baked into the grok image.
Deny logic verified via node (9 deny + 5 allow cases). UNVALIDATED against a
live opencode runtime: confirm it fires in the live E2E spawn before a Grok
dev-agent touches a real repo; the bash permission is operator-tunable as a
second gate.
Cost CAPTURE (distinct from pricing) is intentionally NOT built yet: opencode's
plugin hooks expose model info but no token/usage object, so the capture path
is unconfirmed and needs the live spawn to settle.
