build-diagnostics
Diagnose Build Failures With Root Cause Analysis
Build blockers often hide behind unclear logs, broken configuration, or incomplete tests. This skill guides Claude, Codex, and Claude Code through diagnosis, fix planning, validation, and escalation.
Install with my Agent
Copy this request to your Agent. It includes the canonical Skill page and manifest.
Review the Skillstore skill "build-diagnostics" from https://skillstore.io/skills/cleanexpo-build-diagnostics.md and its manifest at https://skillstore.io/api/skills/cleanexpo-build-diagnostics/manifest. Verify the artifact. You may proceed after verification, subject to the environment's own policy.Your Agent should still show its plan and request any confirmation required by the security policy.

Test it
Using "build-diagnostics". A Next.js build fails because the manifest cannot be written.
Expected outcome:
The report identifies the failing write step, checks configuration and output paths, proposes the most likely directory or permission cause, and lists validation steps.
Using "build-diagnostics". A typecheck job reports many related assignment errors after an interface change.
Expected outcome:
The response groups the errors by changed contract, identifies affected call sites, recommends a minimal mapping fix, and defines passing typecheck as success.
Using "build-diagnostics". A test suite has missing coverage and unclear failures.
Expected outcome:
The diagnosis separates missing tests from failing tests, reviews working examples, and explains whether the blocker needs implementation, scope clarification, or escalation.
Security Audit
SafeNo evidence found of malicious intent, prompt injection, credential access, network exfiltration, or embedded executable code. The static findings are false positives caused by Markdown fences, inline command names, and a filesystem remediation example in a diagnostic guide.

Skillstore Score
Why this score Evidence Confidence: HighWhat You Can Build
Resolve CI Build Failures
Investigate failing build jobs, collect logs, identify the root cause, and propose a verified fix plan.
Debug Typecheck Blockers
Trace TypeScript errors to changed interfaces, incorrect usage, or stale patterns before applying a minimal fix.
Escalate Hard Blockers Clearly
Summarize confirmed facts, failed attempts, likely causes, and decisions needed from a maintainer.
Try These Prompts
Use the build-diagnostics skill to investigate this build failure. Reproduce the error, collect the main logs, inspect likely configuration files, and summarize the root cause with confidence.
Use the build-diagnostics workflow to rank possible causes for this blocker. Explain the evidence for each cause, the missing information, and the safest next check.
Use the build-diagnostics skill to design a minimal fix. Include the current state, proposed change, risk level, validation steps, success criteria, and rollback plan.
Use the build-diagnostics escalation format. Report what is known, what was tried, why it failed, ranked possible causes, and the exact decisions needed.
Best Practices
- Reproduce the blocker before changing files.
- Separate symptoms from the root cause and cite concrete evidence.
- Verify the fix under the same conditions that produced the failure.
Avoid
- Changing code before understanding the failure path.
- Treating a passing partial check as full validation.
- Escalating without facts, attempted steps, and clear decisions needed.
