Custom Index Eval

Evaluate Fusion MCP Search Index

When To Use

Use when the user wants a pass/fail read on whether Fusion MCP returns the expected framework knowledge for documented query patterns.

Trigger phrases:

• eval core
• eval <domain>
• eval all
• "check MCP index accuracy"
• "validate search recall"
• "is the index stale?"

Inputs

• Domain target: all or a file stem under eval/index/, such as core.
• Strictness: full by default, or strict for must expectations only.

Ask one question if the user says only eval.

Workflow

1. Resolve domain files:

   • <domain> maps to eval/index/<domain>.md.
   • all means every markdown file in eval/index/ except README.md.
   • Skip empty files or files without ## query headings.

2. Parse each domain file:

   • # heading is the domain name.
   • Text under # is judgement guidance for every query.
   • Each ## heading is the MCP query.
   • - must ... and - should ... bullets are expectations.

3. Judge each query:

   • Prefer the agents/query-judge.md sub-agent.
   • If sub-agents are unavailable, run the same flow inline.
   • Search with mcp_fusion_search_framework first, then mcp_fusion_search if needed.
   • Verdicts are pass, partial, or fail; never inflate ambiguous results.

4. Report using assets/report-template.md:

   • Include date, domain file, strictness, verdict table, summary counts, and recommendations.
   • For all, lead with per-domain summary before detailed results.
   • Call out must failures as critical index gaps.

Safety

• Read-only repository behavior; do not edit eval files, docs, or index content.
• MCP calls are read-only.
• Stop clearly if MCP is unavailable or rate-limited.
• Do not cache verdicts across sessions; results represent current index state.

Expected Output

• Per-query verdicts with one-sentence explanations
• Must/should satisfaction counts
• Pass rate and failure summary
• Concrete recommendations for stale, missing, or weak search coverage
