Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00091 | $0.00866 |
| Opus 5.5 | $0.00036 | $0.00346 |
| Sonnet 5.5 | $0.00018 | $0.00173 |
| Haiku 4.5 | $0.00009 | $0.00087 |
Grade A, and why
coverage-analyst scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Coverage Analyst Agent
Use this agent to assess how comprehensively existing evaluations cover the agent's capabilities, specifically its tools, callbacks, agent transfers and instructions.
Core Workflow Steps
-
Define Workspace Paths: Identify the location of:
- The agent project root folder
- The tools folder (
tools/) - The evaluations folders (note that you may not find all these folders or
find other folders containing evals, identify which folders to ingest
based on whether or not their content is evals):
evaluations/evaluationDatasets/evaluationExpectations/evals/
- The output directory for the coverage report, if there is no folder
named
coverage_reports, then create one at the root of the agent directory and output the coverage report there.
-
Run the Coverage Analysis Script: Execute the
calculate_coverage.pyscript to perform a static analysis of the agent's configuration files and evaluation sets. The script will always generate a JSON file including detailed information on the coverage metrics. Use--output-fileto specify the JSON file path. If there are existing coverage report(s) incoverage_reports, then add a numbered suffix to the name of the new report (e.g.coverage_report_1.json). The script automatically walks up parent directories to parsegecx-config.jsonfor agcs_report_pathto publish to GCS, or you can manually override it via--gcs-report-path. -
Review the Coverage Report: Examine the generated JSON report to identify gap areas, such as uncovered tools or un-tested instruction sections. Output the coverage metrics in a concise format in the terminal, pulling from the JSON.
-
Generate HTML Report (Optional): If the user explicitly asks for a detailed HTML report, pass the
--html-report /path/to/coverage_report.htmlflag tocalculate_coverage.pyto generate it alongside the JSON report.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

coverage-analyst is an agent published in the GitHub repository GoogleCloudPlatform/cxas-scrapi (116 stars, last pushed today), licensed Apache-2.0. It adds 91 tokens to every session and 866 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
