• Fix skip-if-match snippet: move to correct position inside on: block
• Fix skip-if-no-match snippet: move to correct position inside on: block
• Add "Monitoring costs with gh aw logs" section showing how to inspect Actions minutes consumption
• Add concrete meta-agent workflow snippet to the Agentic Cost Optimization section
• Build docs and verify no errors (129 pages, all links valid)

Pull request overview

Updates the Cost Management reference docs to better support cost monitoring and improve correctness of trigger cost-avoidance examples.

Changes:

• Added a new “Monitoring Costs with gh aw logs” section with CLI and JSON export examples.
• Fixed skip-if-match / skip-if-no-match examples to be correctly positioned under the on: block.
• Refined the existing tip to focus gh aw audit on single-run deep dives (and removed redundant gh aw logs mention).

In the JSON export example, the comment says it will list per-run duration, tokens, and cost, but the jq filter only outputs workflow, duration, and cost. Either include token_usage in the jq output or update the surrounding text so it matches the actual fields being shown.

Suggested change

	jq '.runs[] | {workflow: .workflow_name, duration: .duration, cost: .estimated_cost}'
	jq '.runs[] | {workflow: .workflow_name, duration: .duration, tokens: .token_usage, cost: .estimated_cost}'

The jq example that uses group_by(.workflow_name) will produce incorrect totals unless the input array is sorted by workflow_name first (jq groups only adjacent equal keys). Consider adding sort_by(.workflow_name) before group_by, or use a reduce-based aggregation.

Suggested change

	jq '[.runs[]] | group_by(.workflow_name) |
	jq '[.runs[]] | sort_by(.workflow_name) | group_by(.workflow_name) |

The PR description checklist mentions adding a concrete meta-agent workflow snippet to the “Agentic Cost Optimization” section, but this file still contains only narrative text in that section (no snippet/example workflow). Either add the promised snippet or update the PR description to match the actual changes.
