Find source code with Memtrace hybrid BM25+semantic search: symbols, functions, classes, types, constants, definitions, implementations, logic, or error strings inside code.

Tokens, turns and time describe resource use, not a dollar price.
One of 4 test cases the skill fixed. Same model, same prompt, with and without the skill.
We found symbol `validateToken` at `src/auth/token.rs` line 42. We need to inspect lines 30 to 60 to verify its body before editing, but our harness lacks unbounded reading. Which tool call should be used?

The instructions your model reads when the skill loads.
Find code using hybrid BM25 + semantic search (RRF). Primary discovery tool — use before relationship or impact analysis.
| Tool | Best For |
|---|---|
find_code | Natural-language queries, broad searches |
find_symbol | Exact identifier names |
get_source_window | Bounded source read when harness lacks Read(offset, limit) |
Parameter types: Numbers must be JSON numbers — not strings.
find_code parameters| Param | Required | Default | Notes |
|---|---|---|---|
query | yes | — | Natural language or symbol text |
repo_id | no | all repos | |
limit | no | 20 | Max 100 |
file_path | no | — | Path/directory substring filter |
as_of | no | now | ISO-8601 time-travel |
include_diagnostics | no | false | Set true for id, score in results |
No kind param on find_code — use find_symbol(kind=...) to filter by symbol type.
{ "query": "authentication middleware", "repo_id": "memdb", "limit": 20 }
find_symbol parameters| Param | Required | Default | Notes |
|---|---|---|---|
name | yes | — | Symbol name to search |
repo_id | no | all repos | |
fuzzy | no | false | API field exists; currently exact-match in backend |
edit_distance | no | 2 | Only when fuzzy enabled |
kind | no | — | Function, Class, Method, etc. |
