-| `model` | ❌ | `''` | The AI model used (e.g. `claude-sonnet-4-5`). Used for per-token cost display. |
-| `engine` | ❌ | `claude` | The AI engine (`claude`, `codex`). |
-| `status` | ❌ | `success` | Run outcome. In companion `workflow_run` mode this is resolved automatically from the triggering workflow's conclusion. In inline mode pass `${{ steps.agent.outcome }}` or a custom value like `needs_human`. See [docs/status-values.md](docs/status-values.md). |
-| `agent_output` | ❌ | `''` | Raw stdout from the agent step. Used to auto-extract token counts from JSON. |
-| `input_tokens` | ❌ | `''` | Explicit input token count. Overrides extraction from `agent_output`. |
-| `output_tokens` | ❌ | `''` | Explicit output token count. |
-| `cache_read_tokens` | ❌ | `''` | Cache read token count. |
-| `cache_write_tokens` | ❌ | `''` | Cache write token count. |

-| `pr_number` | ❌ | `''` | PR number created by this run (if any). |
-| `workflow_run_id` | ❌ | `''` | Run ID of the triggering agent workflow (`github.event.workflow_run.id`). Enables auto-resolution of tokens, trigger number, timestamps, and gate logic. |
-| `started_at` | ❌ | `''` | ISO 8601 start timestamp. Overrides self-measured time. |
-| `completed_at` | ❌ | `''` | ISO 8601 completion timestamp. |
-| `trigger_number` | ❌ | `''` | Issue or PR number to comment on. Override when auto-resolution fails. |
-| `trigger_event` | ❌ | `''` | Original event name (`issues`, `pull_request`, etc.). Used with `trigger_number`. |
-| `post_comment` | ❌ | `true` | Set to `false` to skip posting a cost comment. |
-| `api_url` | ❌ | `https://agentmeter.app` | AgentMeter API base URL. Override for local dev or self-hosted. |
-| `github_token` | ❌ | `${{ github.token }}` | GitHub token for comment posting and artifact access. No config needed. |
