feat(v0.34 W3): MCP-expose code_callers / code_callees / code_def / code_refs
...
Pre-v0.34 these four code-intelligence commands lived in CLI_ONLY at
cli.ts:30 — agents calling gbrain via MCP couldn't reach them and fell
through to text search. This commit ships the agent-facing MCP surface
for v0.34 against the existing v0.20+ tree-sitter call graph; recursive
blast/flow and clusters land in subsequent commits.
* `code_callers(symbol, [limit, source_id, all_sources])` — wraps
engine.getCallersOf. Reverse view of the A1 call graph.
* `code_callees(symbol, [limit, source_id, all_sources])` — wraps
engine.getCalleesOf. Forward view.
* `code_def(symbol, [limit, lang])` — wraps findCodeDef. Returns
definition sites with file/line/snippet.
* `code_refs(symbol, [limit, lang])` — wraps findCodeRefs. Returns
every reference (comments, strings, imports, call sites).
All four are scope:'read', source-scoped by default via ctx.sourceId
(W0a contract). Per-call source_id param wins over ctx; pass '__all__'
or all_sources=true to force cross-source.
* operations-descriptions.ts: 4 new constants per the eng review D10
finding — every description carries an inline example response so
agents don't burn first-call context discovering shape. Resolver-grade
wording ("BEFORE editing any function, run code_callers...") routes
plan-mode questions straight to the right op.
* SEARCH_DESCRIPTION gains a cross-link clause pointing at the four new
ops so agents stop falling through to text search for code-symbol
questions.
Tests (11 E2E in test/e2e/code-intel-mcp-ops-pglite.test.ts):
- All four ops registered + scope:read + description pinned by constant
- All four ops have required symbol param
- code_callers / code_callees return the documented envelope shape
- Source scoping honors ctx.sourceId
- all_sources=true / source_id='__all__' force cross-source
- code_def returns the def-site snippet
