## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-08-03.

- **Supply Chain Security**: 87/100
  - No malware found by supply-chain analysis.
  - Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.
  - No install/post-install scripts declared.
  - Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.
- **Provenance & Transparency**: 45/100
  - Source repository is publicly reachable at the declared URL.

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-08-03 (score 66, +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.

### `skill_search` (~424 tokens)

Search the skill registry

Search and browse the skill-builder registry of reusable AI skill prompts.

Use this first to discover what skills exist before installing. Supports free-text
search plus filters and sorting. Read-only; never writes files.

Args:
  \- query (string, optional): free-text search across names, descriptions, tags.
  \- category (string, optional): exact category filter (e.g. "Developer Tools").
  \- author (string, optional): publisher handle (with or without leading @).
  \- tags (string[], optional): require these tags.
  \- type ('basic' | 'meta', optional): 'meta' = skills that orchestrate dependencies.
  \- sort ('relevant' | 'recent' | 'popular' | 'downloads'): default 'relevant' when a
    query is given, otherwise 'recent'.
  \- page (number): 1-based page (default 1).
  \- page_size (number): results per page, 1-100 (default 20).
  \- response_format ('markdown' | 'json'): default 'markdown'.

Returns: a list of matching skills (id, name, description, category, type,
dependency count, downloads). JSON format additionally returns total/page/pageSize.

Example: skill_search { "query": "data pipeline", "type": "meta" }
To install one of the results, call skill_install with its id.

Input parameters:

- `author` (string): Publisher handle (with or without @).
- `category` (string): Exact category filter.
- `page` (integer): 1-based page number.
- `page_size` (integer): Results per page (1-100).
- `query` (string): Free-text search query.
- `response_format` (string): Output format: 'markdown' (human-readable, default) or 'json' (full structured records).
- `sort` (string): Sort order. Defaults to 'relevant' with a query, else 'recent'.
- `tags` (array): Require these tags.
- `type` (string): Filter by skill type.

### `skill_info` (~227 tokens)

Get full details of a skill

Fetch the complete record for one skill: metadata plus the full markdown body
(the actual prompt/instructions). Resolves by id or name. Read-only — unlike an
install, this does NOT count as a download.

Args:
  \- skill (string): skill id ("@handle/slug" or bare "slug") or its display name.
  \- response_format ('markdown' | 'json'): default 'markdown'.

Returns: name, id, type, category, tags, author, version, downloads, dependency
list (for meta skills), the web URL, and the full markdown body. JSON format
returns the raw skill record.

Example: skill_info { "skill": "@kmd_ai/bakefail-pre-flight-auditor" }
If you intend to use the skill in this project, follow up with skill_install.

Input parameters:

- `response_format` (string): Output format: 'markdown' (human-readable, default) or 'json' (full structured records).
- `skill` (string, required): Skill id ('@handle/slug' or 'slug') or display name.

### `skill_suggest` (~154 tokens)

Autocomplete skills, tags, authors

Autocomplete/typeahead over the registry: returns matching skills, tags,
authors, and categories for a (possibly partial) query. Useful for resolving a
vague request to a concrete skill id before calling skill_info or skill_install.
Read-only.

Args:
  \- query (string): partial term to complete (min 1 char).
  \- limit (number): max suggestions, 1-25 (default 10).

Returns: a ranked list of suggestions, each tagged with its kind
(skill | tag | author | category).

Example: skill_suggest { "query": "lit" }

Input parameters:

- `limit` (integer): Max suggestions (1-25).
- `query` (string, required): Partial term to autocomplete.

### `skill_taxonomy` (~123 tokens)

List registry categories, tags, authors

Get the registry's taxonomy: the full set of categories, tags, authors, and
types with counts, plus the total number of skills. Use it to discover valid
filter values for skill_search. Read-only.

Args:
  \- response_format ('markdown' | 'json'): default 'markdown'.

Returns: total skill count and faceted lists of categories, types, authors, and
tags, each with a count.

Input parameters:

- `response_format` (string): Output format: 'markdown' (human-readable, default) or 'json' (full structured records).

### `skill_install` (~641 tokens)

Install a skill into the project

Install a skill from the registry into the current project, writing the files
the target coding tool expects. If the skill is a META skill, its full
dependency tree is resolved (deduped, cycle-safe) and every required skill is
installed alongside it (pass with_dependencies=false to install only the meta
skill itself).

Where files are written, by target:
  \- claude: appends the skill markdown to CLAUDE.md (under a "## <name>" heading
    with a hidden skill-id marker; re-installs are skipped if already present).
  \- codex: same, but to AGENTS.md.
  \- cursor: writes .cursor/rules/<slug>.mdc with frontmatter.
  \- file: writes <slug>.md plus a <slug>.json manifest into output_dir.

Args:
  \- skill (string): id ("@handle/slug" or "slug") of the skill to install.
  \- target ('auto' | 'claude' | 'codex' | 'cursor' | 'file'): default 'auto',
    which sniffs the project (.cursor/, .claude/, CLAUDE.md, AGENTS.md, env) and
    falls back to 'file'.
  \- project_dir (string, optional): project root to install into. Defaults to
    SKILL_PROJECT_DIR or the server's working directory.
  \- output_dir (string, optional): for target 'file', dir relative to project_dir
    (default ".").
  \- agents_file (string, optional): override the CLAUDE.md / AGENTS.md path
    (relative to project_dir) for targets 'claude'/'codex'.
  \- with_dependencies (boolean): install a meta skill's dependencies too (default true).
  \- dry_run (boolean): plan and report what would be written without writing (default false).
  \- response_format ('markdown' | 'json'): default 'markdown'.

Returns: the resolved target and project dir, the ordered install plan, and the
files written/planned for each skill, plus any dependencies that could not be
resolved. This tool WRITES FILES (non-read-only). It never deletes anything.

Example: skill_install { "skill": "@kmd_ai/paperdistillery-orchestrated-literature-to-briefing-pipeline" }

Input parameters:

- `agents_file` (string): Override CLAUDE.md/AGENTS.md path for claude/codex.
- `dry_run` (boolean): Report what would be written without writing.
- `output_dir` (string): Output dir for target 'file' (relative to project_dir).
- `project_dir` (string): Project root to install into.
- `response_format` (string): Output format: 'markdown' (human-readable, default) or 'json' (full structured records).
- `skill` (string, required): Skill id to install ('@handle/slug' or 'slug').
- `target` (string): Target coding tool. 'auto' detects from the project.
- `with_dependencies` (boolean): Install a meta skill's dependencies too.
