How to audit coverage gaps with your AI agent

Connect Codecov to your agent to turn flat coverage numbers into a clear map of your testing blind spots.

Short answer

How can I find coverage gaps using my AI?

Your agent pulls a hierarchical report tree to show you exactly where coverage is thin. It maps out specific files and directories that need attention so you don't have to hunt through raw logs. You'll get a clear list of targets for your next test suite.

The results.

Where your coverage data lands.

The AI processes the report tree to give you actionable insights.

ANALYSIS

Identified blind spots

The agent scans the report tree to find directories with zero or low coverage. You get a list of specific paths that need tests.

PLANNING

Targeted test lists

The AI organizes the missing coverage into a prioritized list. You can use this to decide which files to tackle first.

REPORTS

Structured summaries

Instead of a wall of text, the agent provides a clean breakdown of coverage by folder. This makes it easy to see if entire modules are unprotected.

HUMAN

Manual test writing

The AI identifies the gaps, but you still have to write the actual test code. It points the way, but you do the heavy lifting.

The workflow

What your AI does when the report arrives.

The agent moves from raw data to a structured map of your codebase.

  1. Fetch the tree

    The agent pulls the full hierarchical coverage data from Codecov. This provides the structural context of your project.

    get_coverage_report_tree
  2. Map the gaps

    The agent looks through the tree to find files or folders where coverage is missing. It identifies the specific paths that are unprotected.

    get_coverage_report_tree
  3. Group by directory

    The agent organizes these gaps into a logical hierarchy. This helps you see if a specific module is entirely untested.

    get_coverage_report_tree
  4. Summarize findings

    The agent presents a concise list of the most critical areas to fix. You get a clear starting point for your testing work.

FAQ

How this task behaves.

  • 01

    Can the AI write the tests for me?

    No. The AI identifies where coverage is missing, but you must write the test code yourself.

  • 02

    Does the AI change my coverage data?

    No. The agent only reads the report tree. It cannot modify your Codecov reports or your source code.

  • 03

    Can I see coverage for a specific branch?

    Yes, as long as that branch's coverage data is available in the report tree the agent accesses.

  • 04

    Will the AI fix my CI/CD pipeline?

    No. The agent provides the information you need to make decisions, but it doesn't interact with your CI/CD configuration.

  • 05

    How does it know which files are missing tests?

    It uses the get_coverage_report_tree tool to inspect the hierarchical structure and find files with zero or low coverage percentages.
