[aw-failures] Two daily workflows fail at agent start: Documentation Healer (effort-param 400) & Model Inventory Checker (BYOK auth)

[github-actions]

Recommendation

Two daily scheduled workflows fail at agent start, before any work, due to engine/model configuration — fix both: drop the unsupported effort parameter for Documentation Healer, and restore BYOK auth token plumbing for Model Inventory Checker. Neither is a network/firewall issue (audit-diff shows 0 new domains, 0 anomalies vs the last green run).

This sub-issue root-causes the shallow auto-notifier issues #37010 and #37014.

Cluster A — Daily Documentation Healer: effort parameter rejected (fresh regression)

Fix: remove or guard the effort parameter for the Claude small-agent model (or select a model that supports effort).

• Affected run: 26986947133 (schedule, 2026-06-05T00:01Z) · notifier issue [aw] Daily Documentation Healer failed #37010
• Regression signal: 7 consecutive prior days success, first failure today — failure success success success success success success success.
• Dominant error (all 4 attempts, ~0s each):

API Error: 400 This model does not support the effort parameter.

• Engine = Claude Code, model = small-agent. The --continue retry path then hit Error: No deferred tool marker found in the resumed session (isNoDeferredMarkerError=true) and --continue was disabled permanently. Agent produced 0 real turns / 0 tokens.
• audit-diff (base success [26921451398] vs failure 26986947133): new_domain_count=0, anomaly_count=0, run2_turns=1 — regression is isolated to the agent engine invocation, not networking.
• Failure class: config-error.

Cluster B — Daily Model Inventory Checker: BYOK auth missing (persistent regression)

Fix: restore BYOK token plumbing so the Copilot SDK driver receives valid auth (COPILOT_GITHUB_TOKEN / GH_TOKEN / GITHUB_TOKEN present in the agent env).

• Affected run: 26987484745 (schedule, 2026-06-05T00:16Z) · notifier issue [aw] Daily Model Inventory Checker failed #37014
• Regression signal: 2 consecutive days failing, green before — failure failure success success success success success success.
• Dominant error:

[Error: Execution failed: Error: Session was not created with authentication info or custom provider]

• The Copilot SDK BYOK driver sample (.github/drivers/copilot_sdk_driver_sample_node.cjs) threw an uncaught promise rejection on attempt 1. Harness flagged isAuthError=true: "no authentication information found — not retrying (COPILOT_GITHUB_TOKEN, GH_TOKEN, and GITHUB_TOKEN are all absent or invalid)". The entrypoint unset COPILOT_GITHUB_TOKEN and COPILOT_PROVIDER_API_KEY just before the driver spawned.
• All upstream collect_* setup jobs succeeded; failure isolated to the agent driver; detection/safe_outputs skipped. 0 tokens.
• Failure class: config-error.

Affected workflows and run IDs

Cluster	Workflow	Run	Notifier issue	Failure class
A	Daily Documentation Healer	26986947133	#37010	config-error (effort param)
B	Daily Model Inventory Checker	26987484745	#37014	config-error (BYOK auth)

Success criteria / verification

• Cluster A: Documentation Healer agent phase executes (>0 turns) and the run completes success; no 400 ... effort parameter error.
• Cluster B: Model Inventory Checker driver creates a session; no Session was not created with authentication info error; auth tokens present in the agent env.
• Both workflows green for at least 2 consecutive scheduled runs.
