debug-pipeline from harness/harness-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add harness/harness-skills/debug-pipeline@v2.1.0Pins v2.1.0 in mdr.lock. Pin the fingerprint instead.

Diagnose Harness pipeline executions via MCP. Analyzes any execution (failed or successful) to produce structured reports with stage/step breakdown, timing, bottlenecks, failure details, chained pipeline drill-down, and execution logs. Use when asked to debug a pipeline, investigate a failure, find out why a build failed, analyze pipeline errors, check execution logs, review execution performance, or find bottlenecks. Trigger phrases: debug pipeline, pipeline failed, why did my build fail…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Debug Pipeline Diagnose pipeline executions and suggest fixes via MCP. ## Instructions ### Step 1: Diagnose Execution (Preferred) Use the dedicated diagnosis tool. It accepts an execution_id, pipeline_id (auto-fetches latest execution), or a Harness URL: ``` Call MCP tool: harness_diagnose Parameters: pipeline_id: "<pipeline_identifier>" # or execution_id or url org_id: "<organization>" project_id: "<project>" ``` This returns a structured report with stage/step breakdown, timing, bottlenecks, and failure details in one call. It also automatically follows chained (child) pipeline failures. ### Step 1b: Full Diagnostic Mode For deeper analysis, request logs and pipeline YAML: ``` Call MCP tool: harness_diagnose Parameters: execution_id: "<execution_id>" org_id: "<organization>" project_id: "<project>" summary: false # raw diagnostic payload include_yaml: true # include pipeline definition include_logs: true # include failed step logs log_snippet_lines: 120 # tail N lines per step (0 = unlimited) max_failed_steps: 5 # cap number of steps to fetch logs for ``` ### Diagnose Parameters …

How to install
mdr add harness/harness-skills/debug-pipeline@sha256:c92f3769d754802cThe line at the top of this page pins the label v2.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
