Changelog Test Mapper

Changelog Test Mapper is a skill for Claude Code, Codex from PramodDutta/qaskills. It costs 28 tokens per session (8,101 once invoked), scanned A, original, MIT.

A guide for linking release notes and changelog entries—the records of changes in a software release—to the tests that verify them.

In plain words
What is it for?
Use it to analyze changelogs and commit history, map changes to tests, and find coverage gaps before a release.
Why use it?
It helps reveal user-facing changes and bug fixes that were released without matching test coverage.

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.

Security

Grade A, and why

Changelog Test Mapper scanned grade A with 1 finding 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 6d 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.

Changelog Test Mapper

Every user-facing change in a software release should have corresponding test coverage that verifies the change works as intended. In practice, this mapping between changelog entries and test cases is rarely maintained, leading to releases where features ship without adequate verification and bug fixes lack regression tests. The Changelog Test Mapper bridges this gap by programmatically analyzing changelog entries, release notes, and commit histories, then mapping them to existing test cases and identifying coverage gaps. This skill covers the full pipeline: parsing changelogs in various formats, extracting change metadata, building a bidirectional mapping between changes and tests, scoring coverage completeness, and integrating the analysis into release workflows to prevent untested changes from reaching production.

Core Principles

1. Every Shipped Change Deserves a Test

The fundamental premise of changelog-test mapping is that if a change is important enough to appear in the changelog, it is important enough to have a test. Bug fixes need regression tests. New features need functional tests. Performance improvements need benchmark tests. Changes without tests are unverified promises.

2. Bidirectional Traceability

The mapping must work in both directions. Given a changelog entry, you should be able to find all related tests. Given a test, you should be able to find which changelog entries it covers. This bidirectional traceability enables both forward analysis ("is this release well-tested?") and backward analysis ("what does this test protect?").

3. Automation Over Manual Tracking

Manually maintaining a spreadsheet of change-to-test mappings does not scale. The mapping should be derived automatically from commit messages, PR descriptions, issue tracker links, and file-level change analysis. Manual annotations should supplement, not replace, automated discovery.

4. Coverage Scoring Is Contextual

Not all changelog entries need the same level of test coverage. A breaking API change requires more comprehensive testing than a documentation fix. The coverage scoring model must account for change severity, affected surface area, and historical defect rates.

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.

Changelog Test Mapper is a skill published in the GitHub repository PramodDutta/qaskills (220 stars, last pushed 10d ago), licensed MIT. It adds 28 tokens to every session and 8,101 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
