What is github-actions?

A troubleshooting guide for GitHub Actions, the service that runs automated builds and tests for code repositories. It uses run statuses and logs to help locate failed workflow steps.

Investigating failed GitHub Actions runs, pull-request checks, and jobs when given an Actions URL or error message.

It reduces the time spent searching through failed checks and log output to find the cause of a CI failure.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.01733
Opus 5.5	$0.00000	$0.00693
Sonnet 5.5	$0.00000	$0.00347

Security

Grade A, and why

github-actions scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.

name: github-actions description: Diagnose GitHub Actions workflow failures by retrieving run statuses and logs using MCP tools or gh CLI.

This skill enables autonomous diagnosis of GitHub Actions failures, preferring MCP tools for summaries and falling back to gh CLI.

When to Activate

User reports a failing GitHub Actions workflow, CI failure, or red status check
User provides a GitHub Actions URL (e.g., https://github.com/owner/repo/actions/runs/RUN_ID/job/JOB_ID)
Pull request shows failed Actions checks
Task requires identifying or fixing a workflow failure
Error output references Actions job steps

Step-by-Step Process

Extract IDs from GitHub Actions URL if provided.

If user provides a URL like https://github.com/owner/repo/actions/runs/RUN_ID/job/JOB_ID:
- Extract RUN_ID (numeric) from the URL path
- Extract JOB_ID (numeric) if present in the URL
- Skip to step 2 with these IDs ready to use
Detect available tools for diagnosis.

First, check for gh CLI: run_in_terminal gh --version. If successful, verify access: run_in_terminal gh auth status. Prioritize MCP tools (e.g., list_workflow_runs, get_job_logs) if present — they provide the most token-efficient access. If neither MCP nor authenticated gh is available, respond: 'Automated retrieval of workflow logs is not possible in this environment. Please share the workflow run URL, specific error messages, or screenshots for diagnosis.'
Preferred path: Use MCP tools (if available).

If you have RUN_ID and JOB_ID from URL:
- Use github-mcp-server-actions_get with method get_workflow_job and resource_id=JOB_ID to get job details
- Use github-mcp-server-get_job_logs with job_id=JOB_ID, return_content=true, and tail_lines=100 (or more) to retrieve logs
- Parse logs for failing step, command, and error message
If you only have RUN_ID or need to find failures:
- Use github-mcp-server-actions_get with method get_workflow_run and resource_id=RUN_ID to get run details
- Use github-mcp-server-actions_list with method list_workflow_jobs and resource_id=RUN_ID to list all jobs
- Identify failed jobs (conclusion: "failure") and note their job_id
- Use github-mcp-server-get_job_logs for each failed job

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
