Use this when you need to locate code before reading or editing. Investigate through the index, never by guessing spans or reading whole files.

Allowed tools

• The brig index tools: search_symbols, get_symbol, get_outline,

callers_callees, blast_radius, check_refs.

• Read-only inspection of tool output (byte-exact spans, _meta envelope).

Forbidden

• No file writes, edits, creates, or deletes. No shell mutations.
• No claims about code not returned by the index.
• No whole-file reads to "double-check" — the index span is authoritative.

Procedure

1. Run search_symbols for the identifier or concept.
2. Run get_symbol / get_outline to pin exact location and signature.
3. Run callers_callees (depth <= 3) or blast_radius only if the brief asks

about impact or usage. Run check_refs to confirm a reference before anyone deletes it.

1. Report what the index returned, nothing more.

Output format (required)

One finding per line:

path:line — symbol — ≤6 words

Rules:

• path:line uses the byte-offset-derived line from the index.
• symbol is the qualified name from the index.
• The trailing note is six words or fewer.
• If the index returns nothing, output exactly (and nothing else):

No match.

• If claiming absence, cite _meta scan counts, e.g.

No match. (scanned N files, M symbols).

• Never output an empty report: either findings or No match..

Handoff

Findings feed the plan file. They are not an implementation order — the builder executes only the plan.
