* feat(skills): add content size limits for agent-created skills Agent writes via skill_manage (create/edit/patch/write_file) are now constrained to prevent unbounded growth: - SKILL.md and supporting files: 100,000 character limit - Supporting files: additional 1 MiB byte limit - Patches on oversized hand-placed skills that reduce the size are allowed (shrink path), but patches that grow beyond the limit are rejected Hand-placed skills and hub-installed skills have NO hard limit — they load and function normally regardless of size. Hub installs get a warning in the log if SKILL.md exceeds 100k chars. This mirrors the memory system's char_limit pattern. Without this, the agent auto-grows skills indefinitely through iterative patches (hermes-agent-dev reached 197k chars / 72k tokens — 40x larger than the largest skill in the entire skills.sh ecosystem). Constants: MAX_SKILL_CONTENT_CHARS (100k), MAX_SKILL_FILE_BYTES (1MiB) Tests: 14 new tests covering all write paths and edge cases * feat(skills): add fuzzy matching to skill patch _patch_skill now uses the same 8-strategy fuzzy matching engine (tools/fuzzy_match.py) as the file patch tool. Handles whitespace normalization, indentation differences, escape sequences, and block-anchor matching. Eliminates exact-match failures when agents patch skills with minor formatting mismatches.
