feat(elisp): add coverage-summary to the Elisp bundle with missing-file detection

2026-05-31T16:43:03+00:00

A line-weighted coverage total has a blind spot: a module no test loads never shows up in the SimpleCov report, so it can't drag the number down. The suite looks healthier than it is. This adds a summary that counts every source file on disk against the report and treats an absent file as 0%, weighting the project number by file instead of by line so untested modules stay visible. The script ships at languages/elisp/claude/scripts/coverage-summary.el, self-contained on stock Emacs (just the built-in json). It parses the undercover SimpleCov shape directly rather than depending on the editor's coverage engine, so it runs anywhere the bundle lands. I proved it against a real 103-file report: 93 tracked, 27 untested modules surfaced, project number 66.4%. Delivery follows the bundle convention. The script lives under the gitignored .claude/ footprint and gets auto-fixed on drift by sync-language-bundle.sh, which I made generic for any claude/scripts/* rather than coverage-specific. The Makefile targets ship as a project-owned fragment (languages/elisp/coverage-makefile.txt) that install-lang.sh seeds at the project root and sync drops into .ai/inbox/ when that convention exists. The bundle never edits the project's own Makefile. Tests: 12 ERT for the kernel (Normal/Boundary/Error per function), wired into make test via a new languages/*/tests/ discovery path, plus bats for the sync auto-fix and the inbox-drop guards. This is the Elisp pilot. The pattern is proven, so fanning out to Python, Go, and TypeScript is now a follow-up. Each one needs only its own parser and fragment. The plumbing is already generic.

docs(languages): tighten elisp coding and testing rules

Two audit fixes. elisp.md's "prefer Write over Edits" advice was tool-specific. It's now framed around intent: edit cohesively, then run paren and byte-compile checks immediately, whatever the editing mechanism. elisp-testing.md gains batch-mode reproducibility (emacs --batch as source of truth, no interactive state, no blocking prompts), state isolation (temp user-emacs-directory, explicit load-path, declared deps only), and byte-compile/native-comp warning handling, with native-comp gated on availability and kept opt-in.

feat(rules): port key testing principles from quality-engineer prompt

2026-04-19T18:16:07+00:00

Additions to claude-rules/testing.md: - Testing pyramid proportions (70-80% unit / 15-25% integration / 5-10% e2e) - Integration Tests section: docstring must name 'Components integrated:' and mark real vs mocked; when-to-write heuristics - Signs of Overmocking: 'would the test pass if the function body was NotImplementedError?' plus three more sharp questions - Testing Code That Uses Frameworks: test your integration, not the framework itself - Test Real Code, Not Copies: never inline prod code into tests - Error Behavior, Not Error Text: test type + key values, not exact prose - If Tests Are Hard to Write, Refactor the Code: hard-to-test is a code signal, not a test signal; extract focused helpers - Anti-patterns list extended Addition to languages/elisp/claude/rules/elisp-testing.md: - Interactive vs Internal split pattern: cj/foo wraps cj/--foo; test the internal directly, skip UI mocks Source: ~/.emacs.d/ai-prompts/quality-engineer.org (personal reference, kept as an extended prompt separate from these rules).

chore: remove project-specific references

2026-04-19T18:09:45+00:00

- elisp-testing.md: generalized testutil description. The specific files testutil-general.el / testutil-filesystem.el / testutil-org.el only exist in one project; bundle should describe the pattern, not name specific files. - README.org: install examples use ~/code/ path to match actual layout.

refactor: generalize testing.md, split Python specifics, DRY install

2026-04-19T17:36:04+00:00

claude-rules/testing.md is now language-agnostic (TDD principles, test categories, coverage targets, anti-patterns). Scope header widened to **/*. Python-specific content (pytest, fixtures, parametrize, anyio, Django DB testing) moved to languages/python/claude/rules/python-testing.md. Added languages/python/ bundle (rules only so far; no CLAUDE.md template or hooks yet — Python validation tooling differs from Elisp). Added install-python shortcut to the Makefile. Updated scripts/install-lang.sh to copy claude-rules/*.md into each target project's .claude/rules/. Bundles no longer need to carry their own verification.md copy — deleted languages/elisp/claude/rules/verification.md. Single source of truth in claude-rules/, fans out via install. Elisp-testing.md now references testing.md as its base (matches the python-testing.md pattern).

feat: add per-project language bundles + elisp ruleset

2026-04-19T16:57:23+00:00

Introduces a second install mode alongside the existing global symlinks: per-project language bundles that copy a language-specific Claude Code setup (rules, hooks, settings, pre-commit) into a target project. Layout additions: languages/elisp/ - Emacs Lisp bundle (rules, hooks, settings, CLAUDE.md) scripts/install-lang.sh - shared install logic Makefile additions: make help - unified help text make install-lang LANG= PROJECT= [FORCE=1] make install-elisp PROJECT= [FORCE=1] (shortcut) make list-languages - show available bundles Elisp bundle contents: - CLAUDE.md template (seed on first install, preserved on update) - .claude/rules/elisp.md, elisp-testing.md, verification.md - .claude/hooks/validate-el.sh (check-parens, byte-compile, run matching tests) - .claude/settings.json (permission allowlist, hook wiring) - githooks/pre-commit (secret scan + staged-file paren check) - gitignore-add.txt (append .claude/settings.local.json) Hooks use \$CLAUDE_PROJECT_DIR with a script-relative fallback, so the same bundle works on any machine or clone path. Install activates git hooks via core.hooksPath=githooks automatically. Re-running install is idempotent; CLAUDE.md is never overwritten without FORCE=1.
