Code Review
This pull request integrates the org-wide token-budget breaker (covering the session and weekly_all windows) into the orchestrator's decision path in scripts/agent-rate-limit-gate.sh. The feature is gated behind the AGENT_TOKEN_BUDGET_ENABLED environment variable, keeping it inert and byte-identical to previous behavior when disabled. The changes also include updated documentation and new BATS tests to verify the integration. The review feedback recommends a best-practice improvement in the BATS tests to execute commands using the run helper and immediately assert the exit status, ensuring robust error detection.

Cascade: triage → deep (triage: haiku 4.5 [sonnet 5] → deep: opus 4.8 [sonnet 5] + duck: o4-mini → audit: fable 5)
Summary
Wires the org-wide token-budget breaker (session + weekly_all) into agent-rate-limit-gate.sh's dispatch path for #1155; the feature is disarmed by default (AGENT_TOKEN_BUDGET_ENABLED unset) and fails safe to allow on degraded telemetry. Traced control/data flow: the envelope is fetched once and fed to both library gates, defers are OR-combined, weekly_scoped is correctly excluded, and I reproduced both a correct over-threshold enforce defer and a fail-safe allow on empty telemetry; shellcheck --severity=warning is clean. The two CodeAnt findings are real but minor and only reachable once a maintainer arms the flag, so they do not block a wired-but-disarmed change. No security surface (SAFETY_CHECKS all clean, no secrets/migrations, no downstream impact).
Findings
- minor: argate_token_budget logs the headline 'telemetry OBTAINED (status=200)' purely on HTTP status, so a 200 response with a missing/empty body still reads as OBTAINED even though both windows then fail open for lack of usable data. Reproduced locally: with {"status":200,"body":{}} the headline says OBTAINED while the per-window lines show percent= and the library logs 'allowing dispatch (degraded)'. The dispatch decision remains correct (fail-safe allow) and the degraded signal is still present per-window, so AC #5's OBTAINED-vs-DEGRADED distinction is only partially imprecise, not a functional defect. Consider gating the OBTAINED wording on usable window data being present.
- minor: On a token-window trip argate_token_budget only logs the escalation marker; unlike the per-agent argate_escalate it never posts a tracking-issue comment or applies the needs-human-review label, so an armed trip is not human-clearable or deduplicated through an issue. This is consistent with the function's explicit guard-only ('reads telemetry, never mutates') design and with the library's own arl_token_dispatch (also log-only), and is unreachable until a maintainer arms the disarmed feature. Reasonable as a follow-up rather than a blocker for this wiring PR; worth confirming it is tracked.
- info: Gemini (low priority): some new BATS setup lines (e.g. write_telemetry before the run) execute commands without a
run+ explicit status assertion, so an unexpected setup failure could surface as a confusing pattern-match failure rather than an explicit one. Style/robustness only; does not affect correctness of the tests' assertions.

Reviewed commit: 307c9117ffab450627c5437325a0e8f9a8c8b6f5
Review mode: triage-approved (single reviewer)
Summary
Wires the previously-unreachable org-wide token-budget breaker (session + weekly_all windows) into scripts/agent-rate-limit-gate.sh's decision path, gated entirely behind AGENT_TOKEN_BUDGET_ENABLED (unset by default ⇒ byte-identical to prior behaviour). Adds per-window escalation (dedup marker + needs-human-review label) mirroring the per-agent breaker, updates standards docs to describe the breaker as wired-but-disarmed, and adds 13 bats tests covering enforce/log-only, inertness, degraded-telemetry observability, weekly glide, weekly_scoped exclusion, and escalation dedup (body + comments).
Linked issue analysis
Closes #1155. All 7 acceptance criteria are substantively addressed: (1) the breaker is consulted in argate_gate with defer-from-either-half semantics and an unchanged decision= contract; (2) consultation is skipped entirely when AGENT_TOKEN_BUDGET_ENABLED is unset, with a bats test proving byte-identical output; (3) log-only logs the would-be defer and percent without deferring; (4) session + weekly_all consulted, weekly_scoped never (test pins it at 100% to prove exclusion); (5) OBTAINED vs DEGRADED telemetry states are logged distinctly, including the 200-with-empty-body precision case; (6) enforce+over-threshold defer and flag-unset byte-identical tests present; (7) standards/agent-rate-limits.md and the JSON _note now describe wired-but-disarmed.
Findings
Triage assessment confirmed — no blocking issues. Notes: (a) the change is inert by default; enforce-mode behaviour changes only when a maintainer arms the env flag plus telemetry seam; (b) argate_token_escalate mutations are best-effort with disclosed-failure logging, consistent with argate_escalate; (c) the script does not run under set -e, so read -r -a over the newline-less argate_token_budget output is safe; (d) minor doc nit (non-blocking): argate_token_budget's comment says 'returns 0 always' but the trailing [ ... ] && printf makes it return 1 when no window tripped — harmless since callers capture stdout via process substitution and never branch on its status. Prior review cycle findings (escalation wiring, comment-scan dedup, OBTAINED/DEGRADED headline precision) are all addressed at this SHA; all 6 review threads are resolved and CodeRabbit's changes-requested review was dismissed after fixes. Secret scan: run_secret_scanning MCP tool unavailable in this environment; gitleaks CI check passed.
CI status
All required checks green at 307c911: ShellCheck, Lint, bats config/gate validation, CodeQL, SonarCloud Quality Gate (0 new issues), Agent Security Scan, agent-shield, gitleaks secret scan, duplicate-decl-gate, dependency-audit (npm). Branch is BEHIND main but MERGEABLE; no failing or pending checks.

Summary
Wires the previously-unreachable org-wide token-budget breaker (session + weekly_all windows) into scripts/agent-rate-limit-gate.sh, gated behind AGENT_TOKEN_BUDGET_ENABLED (unset by default ⇒ byte-identical to prior behaviour). A defer from either window defers dispatch under enforce; log-only observes without deferring; tripped windows escalate via deduplicated marker + needs-human-review label on the tracking issue. weekly_scoped is never consulted (ADR §2.5). 14 new bats tests cover arming, inertness, byte-identical output, glide-path defer/allow, degraded-vs-obtained telemetry logging, escalation dedup (body AND comments), and canary discipline. Since the prior approved review at 307c911, the only new commits are a merge of main carrying an automated README refresh (#1161) — the PR's own change content is unchanged. Triage assessment confirmed correct.
Linked issue analysis
Closes #1155, which is substantively addressed: all seven acceptance criteria are covered — the gate now consults both pause-worthy windows in its decision path (AC #1), consultation is inert unless AGENT_TOKEN_BUDGET_ENABLED is set (AC #2, with a byte-identical-output test), log-only logs but never defers (AC #3), weekly_scoped is never consulted with a scope-guard test (AC #4), telemetry OBTAINED vs DEGRADED fail-open are visibly distinct in the log including the 200-with-empty-body edge (AC #5), and enforce-mode defer under a mocked over-threshold envelope is asserted in bats (AC #6). DRY_RUN discipline (AC #7) is preserved.
Findings
No blocking findings.
- Prior cascade (MEDIUM, approved at 7c33177) and prior single-review (approved at 307c911) findings were all resolved; CodeRabbit's changes-requested reviews were addressed and dismissed, and its OBTAINED/DEGRADED precision fix plus the comment-scanning dedup fix are present in this diff with tests.
- All review threads resolved (0 unresolved); no unanswered human-reviewer questions (remaining comments are informational bot notices with recorded dispositions).
- Minor, non-blocking: argate_token_budget's header says 'Returns 0 always', but its final
[ ${#tripped[@]} -gt 0 ] && printfreturns 1 when no window tripped; harmless since the caller consumes stdout via process substitution and never checks the status. - Secret-scan MCP tool (run_secret_scanning) unavailable in this environment — gitleaks CI check is green; no secret-like content in the diff.
- Risk is MEDIUM (non-trivial shell logic in the dispatch gate), not HIGH: no secrets handled, standards/agent-rate-limits.json values untouched (only the _note text), breaker ships disarmed, and test fixtures — not the signed-off config — arm the glide path.
CI status
All required checks green at 09ddd00: ShellCheck, Lint, Validate config and gate library (bats), Secret scan (gitleaks), CodeQL, Agent Security Scan, agent-shield, SonarCloud Quality Gate (passed, 0 new issues / 0 hotspots), duplicate-decl-gate, dependency-audit. No CI security warnings.

Problem
The token-budget breaker is unreachable: agent-rate-limit-gate.sh never consults arl_token_budget_gate or arl_token_weekly_glide_gate
From the issue: Epic #636 closed on 2026-09-07 with phases 1–6 all merged, but the token-budget breaker it delivered cannot fire.
scripts/agent-rate-limit-gate.sh— the only entrypoint any workflow invokes — contains no reference toarl_token_budget_gate,arl_token_weekly_glide_gate, orAGENT_TOKEN_BUDGET_ENABLED. Both breakers are fully implemented inscripts/lib/agent-rate-limit.sh, covered bytests/test_agent_rate_limit_token_budget.batsandtests/test_agent_rate_limit_weekly_glide.bats, and reachable from nothing.Risk
Low — changes automation shell logic under scripts/, covered by shellcheck (--severity=warning) and the bats suite.
