- Around line 181-182: Update the jobs documentation for total_cost_usd to
reflect that the field may be omitted as well as null, and change the example
guard to verify it is a number before calling toFixed().
- Line 172: Update the usage documentation around extractRunUsage and the usage
example to state that usage and token counts are available only when reported by
the runtime, including that usage may be null. Make total_cost_usd optional in
the example and guard it before calling toFixed().
In `@docs/src/content/docs/concepts/triggers.md`:
- Line 537: Update the trigger_type description to stay consistent with the
webhook status documented in the comparison table: remove webhook from the
currently user-configured trigger list unless webhook support is explicitly
available, and preserve the descriptions of the other trigger types.
- Line 541: Update the spawned trigger definition and its corresponding
description to include jobs started programmatically by a host application
through the FleetManager API, not only by another agent; use consistent wording
such as “another agent or host application” in both locations.
In `@docs/src/content/docs/guides/displaying-images.md`:
- Line 263: Update the documented chart workflow around plt.savefig to ensure
the charts directory exists before saving sales-trend.png, preferably by adding
a directory-creation step before running the script or creating it in chart.py.
- Around line 161-165: Update the tool-returned image documentation to describe
the parser contract: document image blocks using source.type "base64" with a
non-empty base64 payload or source.type "url" with a URL, and remove the claim
that raw binary image data is supported.
- Line 84: Update the caching guidance for GET /files/:agentName/* to prevent
cross-user exposure of workspace files: recommend no-store unless identity-bound
authorization, cache keys, and invalidation are implemented. Ensure the
documented Cache-Control value no longer permits shared caching.

| Every completed job records token usage and cost data in the `usage` field. This enables cost tracking, usage analytics, and understanding how your agents consume resources. |

Align the usage documentation with runtime behavior.
extractRunUsage can return no usage, and job-executor.ts preserves usage: null when no accounting exists. Document usage and token counts as available only when reported by the runtime. Because total_cost_usd can be omitted, update the example’s cost guard before calling .toFixed().

Treat total_cost_usd as optional, not only nullable.
The extractor adds total_cost_usd only for finite values. The CLI synthetic result omits it, and job persistence preserves that omission. The example’s !== null check therefore calls .toFixed() on undefined. Document the field as optional or normalize it to null, and use a number check in the example.
