User description

What

• ci.yml gets a changes job (dorny/paths-filter, token: '') that passes since to biome.yml and test.yml.
• Pull requests run biome ci --changed --since and vitest run --changed (unit and integration). Main, manual runs, and PRs touching lockfile, biome, tsconfig, vitest config, package.json or .github run everything.
• Typecheck is incremental (flags on the typecheck script, because tsconfig.json is also used by the emitting build; mcp-apps/tsconfig.json is noEmit only).
• Repo .actrc removed (machine lines only); README line updated. biome.json gets defaultBranch: main.

Why

Biome: "Biome only processes the files that have diffs" with --changed --since=<ref>. Vitest: "You can also pass commit hash (e.g. --changed 09a9920) ... By default, changes to the Vitest config file and package.json will always rerun the whole suite." dorny/paths-filter with token: '' diffs with git against the PR base.

Checks

Local pnpm verify passes. Typecheck src: plain 4.3-5.5s, warm incremental 1.5s; mcp-apps 3.7s then 1.8s; a deliberate type error fails it.

Act (pull_request event, head f25699e): test leg ran the full suite (this PR touches .github), 19 integration and 104 unit files pass, 85s. Probe commit touching one source file: changed-only integration 17 files and unit 17 files pass, exit 0 without --passWithNoTests (vitest 4.1.12 exits 0 when no test is affected).

Closes #203

Summary by CodeRabbit

• Chores

  • CI checks can now focus on files changed in a pull request, while running the full checks when broader changes require them.
  • The standard check command now includes TypeScript checks, with incremental compilation to speed up repeated checks.
  • Local development runner settings no longer rely on a repository-level configuration file.

• Documentation

  • Updated contributor guidance to clarify how local runner settings are configured.

CodeAnt-AI Description

Run focused lint and tests for pull requests

What Changed

• Pull requests now lint and test files changed since the base branch.
• Changes to shared configuration, pushes to the main branch, and manual runs still run the full lint and test suites.
• Repeated typechecks can reuse previous results.

Impact

✅ Faster checks for focused pull requests
✅ Full lint and test coverage for configuration changes
✅ Shorter repeat typechecks

💡 Usage Guide

Checking Your Pull Request

Every time you make a pull request, our system automatically looks through it. We check for security issues, mistakes in how you're setting up your infrastructure, and common code problems. We do this to make sure your changes are solid and won't cause any trouble later.

Walkthrough

CI now selects full or changed-file lint and test runs based on shared-file changes. TypeScript checks use incremental compilation. The repository-level act configuration is removed, and the README describes machine-level act settings.

Changes: CI Checks and Tooling

Layer / File(s)	Summary
Reusable workflows select full or changed-file checks .github/workflows/biome.yml, .github/workflows/test.yml, biome.json	Both workflows accept a since input and fetch full Git history. An empty input runs full checks; a nonempty input selects changed-file checks. Biome’s VCS configuration sets main as the default branch.
CI routes the base commit to reusable workflows .github/workflows/ci.yml	A new changes job filters shared configuration and dependency paths. It passes an empty value or the pull request base SHA to the Biome and test workflows. The CI gate and main-branch failure-reporting job also wait for this job.
Incremental typechecking and act settings package.json, mcp-apps/tsconfig.json, .actrc, README.md	Typecheck scripts enable incremental compilation and set build-info paths. The root .actrc is removed, and the README now describes machine-level ~/.actrc settings.

Full details: Linked Issues check

Explanation

Issue #203 coding requirements are implemented. .github/workflows/ci.yml computes a pull request base SHA and passes it to the reusable Biome and Vitest workflows. Configuration, lockfile, package, and .github changes select full runs. Non-pull-request runs also pass an empty value and select full runs. .github/workflows/biome.yml uses biome ci --changed --since, and .github/workflows/test.yml uses Vitest --changed for integration and unit tests. package.json and mcp-apps/tsconfig.json enable incremental typechecking with build information under node_modules/.cache/tsc. The repository .actrc is deleted.

Full details: Out of Scope Changes check

Explanation

The reviewed changes stay within Issue #203. The workflow inputs and changes job implement changed-only checks and full-run conditions. biome.json sets the branch used by Biome's VCS integration. The README update documents the .actrc removal. No unrelated implementation or test changes are present in the supplied change summary.

Full details: Docstring Coverage

Explanation

No functions found in the changed files to evaluate docstring coverage. Skipping docstring coverage check. Docstring coverage is scoped to functions touched by this diff. Analyzed 0 functions across 0 files. (7 skipped: 7 unsupported.)

Validate the correctness of the flagged issue. If correct, How can I resolve this? If you propose a fix, implement it and please make it concise.
Once fix is implemented, also check other comments on the same PR, and ask user if the user wants to fix the rest of the comments as well. if said yes, then fetch all the comments validate the correctness and implement a minimal fix

Kept as designed: the coverage thresholds are repo-wide, so a run limited to related tests cannot meet them. Any PR that touches shared config (lockfile, biome, tsconfig, vitest config, package.json, .github) and every push to main still runs the full suite with the coverage gate.

[codeant-ai]

✅ Customized review instruction saved!

Instruction:

Do not flag changed-file test runs for omitting repo-wide coverage when the full suite with coverage thresholds runs for shared-configuration changes and pushes to main.

  CodeAnt PR Risk

🟡  Medium Risk

• The PR needs attention before merging.
• Ordinary pull requests run only tests related to changed files, so they skip the repo-wide coverage gate and can merge without checking coverage thresholds.
