WalkthroughAdded three maintenance skills. They define routines for fixing leaky abstractions, removing dead code, and consolidating duplicate abstractions. ChangesMaintenance skill definitions
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to This PR adds maintenance routines whose current guidance could drop observable behavior during deduplication or delete live code when usage evidence is incomplete; the probe example can also create false cleanup signals. The change should not merge until these bounded correctness risks are addressed. Poem

Cover all supported deep-import forms.
The command at Line 16 matches only imports that contain from "..." or from '...'. It misses side-effect imports such as import "foo/internal/x", CommonJS require("foo/internal/x"), and dynamic import("foo/internal/x"). Those callers can bypass the public surface and remain undetected. Add AST-based matching or explicit patterns for the import forms used by the repository.

Make the probe example non-operational and date-driven.
The harvest command at Lines 48-50 searches for the exact token used at Line 39. It will report this tracked SKILL.md example as a real probe. The literal dates also become stale after August 23, 2026. On August 31, 2026, the example is already expired and can violate the seven-day rule when copied. Use a non-matching documentation marker, exclude SKILL.md files from harvesting, and require remove-after to equal the insertion date plus seven days.

Require complete log coverage before deleting code.
The routine treats Never fired as proof even when the log source is unavailable, sampled, expired, environment-limited, or missing representative traffic. It can then delete live code that is not statically provably dead. Require a successful coverage and retention check for every supported environment. If evidence is incomplete, retain both the probe and the code and record the result as inconclusive.

Do not drop divergent behavior during unification.
Lines 38-40 allow the routine to prefer the newest or most-tested variant and record dropped behavior. That can change observable behavior. It also contradicts Lines 46-47, which require behavior-preserving changes and require stopping when behavior would change. Replace this fallback with “stop and open an issue” until every difference is proven intentional or explicitly handled.
