docs(skills): tighten descriptions under 1000 chars

Trim each long description to <=1000 chars while preserving content (phases, when-to-use, when-not-to, companion references). Frees enough per-session skill-listing budget to quiet the truncation warning on small-context models.

+description: Add test coverage to under-tested code through four phases — Analyze, Propose, Write, Report. Phase 1 inventories code and flags testability-blocked functions (so coupled to UI/framework that testing would mock the code under test). Phase 2 presents a plan and stops for user approval, with per-function pairwise-vs-exhaustive choice for parameter-heavy functions and refactor-or-skip for testability-blocked ones. Phase 3 writes Normal/Boundary/Error tests and diagnoses test-vs-code failures instead of reflexively patching either side. Phase 4 reports test count, coverage change, bugs surfaced. Refactors testability-blocked functions into pure helper + interactive wrapper before testing rather than mocking it. Use when raising coverage on existing code. Do NOT use for TDD on new code (inline), a single failing test (just fix it), characterization snapshot (write directly), or happy-path smoke test. Companion to `/pairwise-tests` and the Normal/Boundary/Error discipline in `testing.md`.
