Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score →
Supply Chain Security87
- No malware found by supply-chain analysis.Pass
- Only part of the dependency tree could be resolved (145 of 149), so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- Only part of the dependency tree could be resolved (145 of 149), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency97
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Cryptographically verified build provenance (signed, bound to levnikolaevich/claude-code-skills). View diagnostics → Pass
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 67 days ago).Pass
- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability36
- AI-judged instruction clarity (fair).Partial
- Context-footprint check failed: tool/resource definitions use about 1759 tokens (~195/item across 9 items; 9 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management27
- Stability observed for 8 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Capabilities100

- 4 Aug 26 +1
No change was recorded against any check on this day. Stability & Change Management went from 23 to 27. That category is still filling its 30-day observation window: 7 days of observed history at the previous scan, 8 at this one. The score rises as the window fills, whether or not the server changes.

Dependencies 145 packages
145 packages in the resolved dependency tree · 144 deprecated · 49 stale.
The dependency tree was only partially resolved, so these counts may be incomplete.
The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability.
bulk_replace Bulk Replace ~184
Search-and-replace text across multiple files inside an explicit root path. Use for renames and refactors when the project scope is known.
| Name | Type | Req | Description |
|---|---|---|---|

edit_file Edit File ~479
Apply hash-verified partial edits to one file. Batch ALL hunks for the same file into ONE call via the `edits` array -- separate sequential edit_file calls on one file go stale and conflict (the most common edit failure). Carry base_revision only for a genuinely later follow-up after the file changed. Anchors accept tag.N, a bare line number, or unique line content (auto-resolved); range_checksum accepts "auto" to compute it for the current range. Preserves existing line endings and trailing-newline shape; conservative conflicts return retry helpers. boundary_mode=inclusive deletes the anchor lines themselves; new_text must close any delimiter whose opening falls inside the replaced range.

|---|---|---|---|
| allow_external | boolean | — | Allow editing a path outside the current project root. Use only when you intentionally target a temp or external file. |
| base_revision | string | — | Prior revision from read_file/edit_file. Enables conservative auto-rebase for same-file follow-up edits. |
| conflict_policy | string | — | Conflict handling (default: "conservative"). "conservative" returns structured CONFLICT output with recovery_ranges, retry_edit/retry_edits, suggested_read_call, and retry_plan when available. |
| dry_run | boolean | — | Preview changes without writing |
| edits | — | yes | JSON array of canonical edits. [{"set_line":{"anchor":"ab.12","new_text":"x"}}] [{"replace_lines":{"start_anchor":"ab.10","end_anchor":"cd.15","new_text":"x","range_checksum":"10-15:a1b2"}}] [{"inser… |
