alexei.dolgolyov ce86949ded docs(code-search): refresh vex vs ast-index notes for vex 1.9.1 / ast-index 3.41.0
- Re-bench on 2026-05-26 against vex 1.9.1 and ast-index 3.41.0.
- Flag findings that flipped vs the 2026-05-18 snapshot:
  - ast-index Python call graph now populated (was empty in 3.27)
  - vex implementations now handles generic-parameterized subclasses (v1.7.0)
  - vex usages is now AST-precise on T1 languages; ast-index is now the
    textual-match tool, inverting the old precision finding
  - vex now has diff --base <rev>, making the "only ast-index has
    changed --base" finding obsolete
  - vex now ships prebuilt Windows binaries; vex self-update works
- Document new vex 1.5 -> 1.9 commands: diff, paths, reachable, check,
  bundle (symbol/pr-impact/project), eval, self-update, capabilities.
- Add README entry for the doc; it was previously missing from the index.
- Bump README "Last updated" to 2026-05-26.

Claude Code Facts

Last updated: 2026-05-26

A collection of interesting and useful facts, tips, tools, and guides for working with Claude and Claude Code.

Contents

Claude Code Tools & Extensions

MCP servers, skills, and plugins that extend Claude Code — including Context7 (library docs), AST Index, and vex (fast code search with semantic embeddings).

Gitea Release Workflow (Minimal)

Minimal Gitea Actions workflow: push a v* tag → create a Gitea release with optional RELEASE_NOTES.md. No builds, no artifacts — just a release entry.

CI/CD for Python Apps on Gitea

Reusable reference for building CI pipelines, release automation, and installer packaging for Python apps on Gitea — covering lint/test workflows, cross-compiled Windows builds (embedded Python + NSIS), Linux tarballs, Docker images, and Gitea REST API release management.

Windows Code Signing for Open-Source Projects

Review of code signing options for Windows executables — Azure Trusted Signing ($9.99/mo, immediate SmartScreen trust), SignPath.io (free but GitHub-only), SSL.com, Certum, and self-signed. Includes CI/CD integration examples for Gitea Actions.

Gitea Act Runner — Worker Capacity (TrueNAS)

How to configure parallel job capacity for Gitea Act Runner on TrueNAS. Covers the CONFIG_FILE env var requirement, custom config.yaml mount, and capacity tuning.

Code Search: vex vs ast-index — Benchmark Notes

Point-in-time benchmark of vex and ast-index on a real mixed-language repo — indexing footprint, query latency, precision findings, and when to fall back from one to the other. Refreshed for vex 1.9.1 / ast-index 3.41.0, with a summary of what flipped since the previous snapshot.
