chroma

Open-source embedding database for AI applications. Store embeddings and metadata, perform vector and full-text search, filter by metadata. Simple 4-function API. Scales from notebooks to production clusters. Use for semantic search, RAG applications, or document retrieval. Best for local development and open-source projects.

Quality

Content

72%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The body is highly actionable with comprehensive executable examples, but it wastes tokens by duplicating integration content that already lives in a reference file, omits validation for destructive operations, and underuses its single reference.

Suggestions

Remove the inline LangChain and LlamaIndex sections and replace them with a one-line pointer to references/integration.md to eliminate duplication and fix progressive disclosure.

Add explicit validation/verification steps (e.g., confirm collection exists before delete, verify deletion count) to the destructive delete operations so workflow clarity can exceed the cap of 3.

Drop the time-sensitive 'Metrics' block (GitHub stars, forks, v1.3.3 version) or move it to a reference, since version numbers and star counts decay and add tokens without aiding execution.

DimensionReasoningScore

Conciseness

Mostly lean and code-forward, but the LangChain/LlamaIndex integration is duplicated inline and in references/integration.md, and the time-sensitive 'Metrics' block (stars, forks, v1.3.3) adds padding that could be trimmed.

4 / 5

Actionability

Extensive copy-paste-ready executable Python covering add/query/get/update/delete, filters, embedding functions, persistence, and server mode, matching the score-5 anchor for fully executable guidance.

5 / 5

Workflow Clarity

Individual operations are sequenced, but destructive operations (delete collection/documents) and batch adds have no validation/verification steps, which per the rubric caps workflow_clarity at 3.

3 / 5

Progressive Disclosure

Sections are well-organized, but the one reference file (integration.md) is duplicated inline rather than pointed to, and there is no signaled navigation to it, matching the score-3 anchor.

Description

92%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description is strong: it concisely states concrete capabilities and gives explicit, natural-language use triggers with a clear niche. The only gap is slightly incomplete trigger-term coverage (missing synonyms/extensions).

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'Store embeddings and metadata, perform vector and full-text search, filter by metadata' — with comprehensive coverage of core operations, matching the score-5 anchor.

5 / 5

Completeness

Explicitly answers both 'what' (store/search/filter embeddings) and 'when' ('Use for semantic search, RAG applications, or document retrieval') with concrete trigger phrases, matching the score-5 anchor.

5 / 5

Trigger Term Quality

Good natural-term coverage ('semantic search, RAG applications, or document retrieval', 'embeddings') but missing common synonyms and file extensions, so it falls short of the comprehensive score-5 anchor.

4 / 5

Distinctiveness Conflict Risk

Clear niche as an open-source, local/self-hosted embedding database with distinct RAG/semantic-search triggers and minimal overlap risk with managed alternatives, matching the score-5 anchor.
