sense is a skill for Claude Code from m3data/sense-mcp. It costs 21 tokens per session (375 once invoked), scanned A, original, Apache-2.0.

A semantic search tool for finding related information in indexed project records, documentation, research, and code.

In plain words
What is it for?
Use it to investigate how something works, find architecture decisions, locate deployment documentation, or trace related code and research.
Why use it?
It helps when you know the topic but not the exact words used in the stored material. Filters can narrow results to a project or source type.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sense scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Search the indexed ecosystem using the sense_search MCP tool.

With arguments

Parse $ARGUMENTS as follows:

  • The main text is the search query
  • --project <name> filters to a specific project
  • --type <source_type> filters by type (trace, documentation, project_claude, reference, research, teaching, code)
  • --limit <n> sets max results (default 10)
  • --mode <mode> overrides Vibe Harness mode for search shaping (explore, build, think-with, ship, cool-off, none). Omit to auto-detect. Use none to force flat cosine search regardless of Vibe Harness state.

Examples:

  • /sense how does authentication work
  • /sense API error handling --project backend
  • /sense deployment configuration --type documentation --limit 5
  • /sense architecture decisions --mode explore

Without arguments

When $ARGUMENTS is empty, synthesize a search query from the conversation context:

  1. Review the last 3-5 exchanges in the current conversation
  2. Identify the core topic, concepts, or question being discussed
  3. Compose a 3-8 word query that captures the semantic thread
  4. Prefix results with "Searching for: [synthesized query]" so the user sees what was searched
  5. Call sense_search with the synthesized query

This enables mid-conversation discovery — just type /sense to surface related prior work without crafting a query.

General

Call sense_search with the parsed arguments and display the results. If the index is empty, suggest running /sense-sync first.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
