[aw] Test Copilot Add Reviewer could not verify daily AI credits

### Workflow Failure

**Workflow:** [Test Copilot Add Reviewer](https://github.com/githubnext/gh-aw-test/blob/15388/merge/.github/workflows/test-copilot-add-reviewer.md)
**Branch:** test-pr-1789360756-15198-14374
**Run:** https://github.com/githubnext/gh-aw-test/actions/runs/34806861344
**Pull Request:** [#15388](https://github.com/githubnext/gh-aw-test/pull/15388)

> [!WARNING]
> **Daily Workflow AI Credits Could Not Be Verified**: The agent was not started because the daily guardrail could not prove complete AI Credits accounting for earlier workflow runs.

**Guardrail status:** `transient_error`

**Reason:** Daily workflow AI Credits are unknown: Missing accounting for executed agent component in run 34805041983 (attempt 1, job 103855363360, conclusion success): agent/token_usage.jsonl is empty; agent_usage.jsonl is missing; agent_usage.json is missing

The guardrail fails closed either because a billable component's usage artifact is missing, empty, or unreadable, or because the guardrail could not reach the GitHub API to verify prior runs. The detailed reason above identifies the specific cause.

This means a billable component in a prior run completed without leaving a valid accounting record. Inspect the affected prior run and its component logs. Once that run leaves the rolling 24-hour window, the guardrail can evaluate the remaining runs normally.

### Action Required

**Assign this issue to an agent** to debug and fix the issue.

Debug with any coding agent

Use this prompt with any coding agent (GitHub Copilot, Claude, Gemini, etc.):

````
Debug the agentic workflow failure using https://raw.githubusercontent.com/github/gh-aw/main/debug.md

The failed workflow run is at https://github.com/githubnext/gh-aw-test/actions/runs/34806861344
````

Manually invoke the agent

Debug this workflow failure using your favorite Agent CLI and the `agentic-workflows` prompt.

- Start your agent
- Load the `agentic-workflows` skill from `.github/skills/agentic-workflows/SKILL.md` or
- Type `debug the agentic workflow test-copilot-add-reviewer failure in https://github.com/githubnext/gh-aw-test/actions/runs/34806861344`

> [!TIP]

> Stop reporting this workflow as a failure

> To stop a workflow from creating failure issues, set `report-failure-as-issue: false` in its frontmatter:

Start with the failed Test Copilot Add Reviewer run and the affected prior run 34805041983, then read debug.md or .github/skills/agentic-workflows/SKILL.md. Trace why the agent accounting artifacts are empty or missing; done means the prior run produces valid accounting and the daily AI credits guardrail verifies it successfully.
