What it does
Test Failure Diagnosis is an agent skill from aztfmod/terraform-provider-azurecaf. Analyze test failure output to identify root cause and suggest fixes. Use when build or test failures occur. Triggers on: test failures, build errors, CI failures.
Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Testing & QA, covering Failing and flaky tests. The repository describes itself as: Terraform provider for the Terraform platform engineering for Azure. The licence is MIT.
When your agent uses it
- Test failures occur
- : test failures
Example prompts
- “/test-failure-diagnosis”
Requirements
- Python 3
Workflow steps
5 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit ac74615. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
python3go
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Test Failure Diagnosis loads about 559 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 224 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Test Failure Diagnosis
Procedure
1. Classify failure type
Read the failure output and classify:
| Failure type | Indicators | Common cause |
|---|---|---|
| Compilation error | cannot compile, undefined:, syntax error | Bad JSON in resourceDefinition.json, invalid Go syntax |
| JSON parse error | json: cannot unmarshal, unexpected end of JSON | Missing comma, unmatched quotes, bad escapes in resourceDefinition.json |
| Duplicate slug | duplicate key, ambiguity errors | Two resources share the same slug |
| Test assertion failure | FAIL, expected X got Y | Naming logic bug, regex mismatch |
| Regex error | error parsing regexp | Invalid regex pattern in validation_regex or regex field |
| Import error | cannot find package, module not found | Missing dependency, go.mod issue |
2. Extract failure details
From the output, extract:
- Failed test name(s): The specific
Test*function(s) that failed - Error message: The assertion or error text
- File and line: Where the failure occurred
- Expected vs actual: What was expected and what was produced
3. Identify root cause
Based on the classification, check the most likely source:
For JSON errors:
python3 -c "import json; json.load(open('resourceDefinition.json'))"For duplicate slugs:
grep '"slug":' resourceDefinition.json | sort | uniq -dFor regex issues:
grep -n 'validation_regex\|"regex"' resourceDefinition.json | grep -v '"\"'4. Suggest fix
Provide a specific, actionable fix:
- For JSON formatting: show the exact line and the correction
- For duplicate slugs: identify which resources conflict
- For regex: show the invalid pattern and the corrected version
- For test failures: show what the test expects and how to satisfy it
5. Verify fix
After applying the suggested fix, re-run the failed test:
go test ./azurecaf/ -run "<failed_test_name>" -v© aztfmod, MIT. Rendered from Markdown: HTML in the file is shown as text, images as links, and headings moved down two levels. Raw file
