The cfn-lint template-discovery step in review.sh piped the repo's whole
matched-file list into 'xargs -I{} sh -c "grep -l {}"'. On the orchestrator
monorepo — especially from a deep worktree path, where every matched path is a
long absolute path — xargs -I{} packs all paths into one assembled command and
aborts with 'xargs: command line cannot be assembled, too long'. The subprocess
exits non-zero having emitted ZERO findings, so the global pre-push hook BLOCKS
every push (agents were working around it with --no-verify).
Fix: switch the grep stage to NUL-delimited, un-batched xargs
(find ... -print0 | xargs -0 grep -lE ...). xargs -0 (no -I) splits the input
across multiple grep invocations, so the argv never exceeds ARG_MAX; grep -l
reports the same matching files as the old per-file grep, and -print0/-0 is safe
for paths with spaces/newlines. The first 'xargs -I{} find {}' is kept (find
needs the start path before its expression) and is bounded by the scope-path
count, so it is not an overflow source. Trailing '|| true' preserves the old
no-match/no-files semantics (TPLS = list-of-templates or empty, never fails).
Purely an argv-batching fix: the scanned file set, findings, and exit codes are
unchanged. Verified exit-code-identical: clean tree -> exit 0 (PASS); planted
GitHub PAT + RSA private key -> exit 1 (BLOCK, gitleaks high); planted CFN
template with a cfn-lint error on a deeply-nested path -> exit 1 (cfn-lint flags
it, no overflow). The previously-overflowing command now completes clean.
* feat(agent-team): read-only CI-result fetcher for P3 verify gate (opt-in, inert)
ci_fetcher.py: fail-closed CiResultFetcher reading the GitHub Actions run
conclusion via a read-only PAT (AGENT_TEAM_CI_READ_TOKEN→GITHUB_TOKEN), returns
{run_id,conclusion,diff_hash} or None on any error. Data-fetcher only — ci_gate
owns the verdict; never writes, no OIDC/AWS, never reads patch artifacts.
coordinator gains opt-in gated_build_verify_wiring() composing it via
bind_ci_result_fetcher; NOT wired into the default run-team.py path. 20 tests.
* harden(agent-team): P3 apply/verify workflow — GitHub App token, CWE-94, fail-closed
Decision-1 auth model: gate-and-pr uses a GitHub App installation token
(pull-requests:write) behind the agent-apply environment; ALL OIDC/id-token/AWS
removed. Hardening: task_id env-indirection (CWE-94 — GitHub expands ${{ }} into
the run shell before exec, so %s/quoting is insufficient); run-id pinning on both
download-artifact; post-build denied-path check (build-hook writes into denied
paths fail the job); empty-hash fail-closed in BOTH the embedded gate (fixed a
real ''=='' pass bug) and ci_gate.py. App-token + draft-PR steps stay if:${{ false }}
until provisioning (App + environment + branch protection). +17 tests.
* harden(agent-team): apply P3-live security-gate fixes (GPT-4.1 xreview + sh-security-review)
BLOCK-1/FIX-4: gate-and-pr re-comments pull-requests:write + environment:agent-apply
(provisioning-time uncomment) and gains needs.guard/build-test=='success' job guard —
zero privilege until provisioning. BLOCK-2/3+FIX-5: ci_fetcher validates run_id (^[0-9]{1,20}$),
owner/repo (^[A-Za-z0-9_.-]{1,100}$), and fetched_id (int) — fail closed, no SSRF/path
injection. FIX-1: conclusion allowlist. FIX-3: api_root removed from public builder (no
injectable endpoint). INJ-02: post-build denied-path check uses NUL-delimited git output +
explicit rename parsing, no backslash mangling, non-UTF8=violation. INJ-03: all three trust-
control denylists unified to one 22-entry union + drift-guard test. Q1: documented run_id/
diff_hash trust source (dispatcher/ledger only). 884 tests, ruff clean. Privileged steps stay
if:${{ false }} until provisioning.
* build(security-review): prune .claude worktrees from deterministic scanners
Agent worktrees under .claude/worktrees/ are full repo copies; the cfn-lint
find|xargs template scan overflowed ('command line cannot be assembled') and the
pre-push hook fail-closed to BLOCK whenever a worktree was present. Prune .claude
in the cfn-lint find + semgrep/checkov excludes, and gitignore .claude/ so it is
never scanned or committed. Unblocks main-tree pushes during parallel agent work.
The prior exclusion (--skip-path cdk.out) stopped the CDK-repo stall but also
silenced checkov on cdk.out/<stack>.template.json — the actual deploy artifact —
losing real S3/IAM IaC coverage (CKV_AWS_53-56, CKV_AWS_111). Switch to skipping
only the cdk.out asset.<hash>/ dependency bundles (the stall cause) so the
synthesized templates are still scanned.
- --skip-path 'cdk\.out/asset\.' anchors to cdk.out so a source file literally
named asset.* is not also excluded; keeps cdk.out/*.template.json scanned.
- venv/dist/build kept as bare names (match anywhere); .venv/.aws-sam escaped.
cfn-lint + semgrep already prune these trees (prior commit). gitleaks runs in
git-mode and respects .gitignore, so cdk.out is already skipped there.
Verified: shellcheck clean; synthetic cdk.out test confirms the stack template is
scanned while asset.* is skipped; the orchestrator's own --scanners-only gate
still exits 0 with suppressions (inert on non-CDK repos: A1==A2 findings here).
cfn-lint, semgrep, and checkov were scanning synthesized/vendored output
(cdk.out, node_modules, .venv/venv, .aws-sam, dist, build). On CDK repos this
explodes the find/xargs arg list and stalls the scan, and flagging synthesized
templates is wrong. Prune those trees in the cfn-lint find, and pass
--exclude / --skip-path to semgrep / checkov.
The global pre-push hook, the /sh-security-review prompt, and finding.schema.json
previously lived only in ~/.config/git and ~/.claude (untracked) — unreproducible.
Source them here: add hooks/pre-push, rewrite install-hooks.sh with a --global mode
(lays down both hooks, sets core.hooksPath, links skill+schema into ~/.claude) and a
per-repo mode. Align pre-commit with pre-push (honor skip marker + suppressions). Add
semgrep p/javascript so the scanners cover the org's Node/.NET repos.
Trigger-agnostic pure-code gate that merges deterministic-scanner findings
(semgrep/gitleaks/checkov/cfn-lint/pip-audit) with agent findings from
/sh-security-review, dedups, applies justification-required suppressions, and
makes the block decision (exit 1 on confirmed critical/high). Phase 2 of the
Sea Haven security-review agent; Path B (CI/headless) wiring lands in Phase 3.
