Nat Path Checks Agent Skill

NeMo Agent Toolkit Path Checks

Use this skill when CI reports failed path checks from ci/scripts/path_checks.py, especially when copied CI output lists entries like:

Failed path checks:
- docs/example.md:40:10 -> data/test1

Workflow

• Open each reported file at the exact line before editing.
• Classify the reported token by meaning, not just by shape.
• Apply the smallest fix that preserves meaning.
• Re-run path checks and Markdown link checks on the changed files.

Fix Decision Table

| Reported token means | Preferred fix | Example |

| --- | --- | --- |

| Prose shorthand, not a path | Rewrite in words. Do not hide it in code just to silence CI. | linux/amd64 -> linux or amd64; pass/fail -> pass or fail |

| Two field names or concepts | Name each item separately, usually as code spans if they are literal fields. | question/answer -> question and answer |

| Exact CLI, protocol, API, config, or method literal | Wrap the literal in inline code, or use a fenced code block for multi-line examples. | tools/list -> tools/list |

| Placeholder path in prose | Wrap the placeholder in inline code. | path/to/workflow.yml -> path/to/workflow.yml |

| Placeholder paths in a list or snippet | Use a fenced code block with an appropriate language or text. | Put data/test1 and data/test2 inside a fenced block. |

| Real repo-relative path | Make the path correct relative to the current file, and link it when useful. | README |

| Intended generated output path | Use inline code or a fenced block unless the file should already exist in the repo. | ./output/results.json |

| Repeated false positive across many docs | Prefer a local wording or escaping fix. Add ALLOWLISTED_WORDS, IGNORED_PATHS, or ALLOWLISTED_FILE_PATH_PAIRS only for true checker limitations. | Add an allowlist only after confirming the token should pass everywhere. |

Important Distinctions

• If a slash token is not meant to be copied exactly, rewrite it as prose.
• If a slash token is meant to be copied exactly, put it in Markdown code.
• If a slash token points to a real file in the repository, fix the target instead of escaping it.
• If data/test1 is an example input path, use data/test1. If it is a real checked-in path, link to the real file or correct the path.
• Do not replace a meaningful relative path with different wording unless the path was never meant to be literal.

Validation

Run these from the repository root after editing:

uv run ci/scripts/path_checks.sh
uv run pre-commit run markdown-link-check --files path/to/changed.md

If a copied CI log contains many failures, fix one file at a time and re-run path checks before applying the same pattern broadly.
