📄 Description

Summary

trace_feature advertised "operation count" in its tool description, but its output schema and successful results contain no count. Fixes #5507.

Problem and expected behavior

listTools described the result as "observations, operation count, and residual unknowns". The result (structuredContent.normalized_result) has only query, search_mode, matches, references, truncated, residual_unknowns. The description, schema and result should agree. "Operation" has no defined unit, so returning a count would mean inventing a meaning (and a count derived from rows would not measure provider work).

Change and scope

Reworded the description to name the members actually returned ("matches, references, and residual unknowns"). Added a boundary test comparing the advertised description and output-schema members. Intentionally excluded: adding a count, changing trace behavior, and #5503 (string encoding qualifications).

Contribution scope: not applicable (wording/contract fix within an existing tool).

Contract and boundary impact

Semantic owner and earliest changed stage: src/contracts/enhancedToolContracts.ts (tool catalog description)
Contribution scope fit and linked maintainer decision: not applicable
CLI and MCP/tool-catalog contract: trace_feature description text only; input and output schemas unchanged
Provider, bridge, target-format, or platform compatibility: none; provider-independent text
Evidence, artifact, provenance, or reconstruction contract: unchanged
Target selection, authority, upstream behavior, and cleanup details: not applicable
Generated metadata: npm run docs:check passed; no catalog change committed

Expected effects:

Read existing files or captured data.
Launch or attach to a process.
Inject instrumentation or run scripts/code.
Change process memory, registers, files, or configuration.
Contact network services.
Recover protected code or work around protections.
Documentation or usability only; no target interaction.
Not sure yet; investigation or maintainer guidance needed.

Evidence and regression coverage

Tests added or updated: tests/boundary/mcp/enhancedTools.traceFeatureCoverage.test.ts (new case: description has no unreturned count promise; normalized_result schema members are the six returned)
Base reproduction or other evidence: executed. With the description change stashed, the new test fails: expected 'Trace the complete literal query, pre…' not to match /count/i; with it restored, 11/11 pass. The original Hopper MCP reproduction in the issue was not re-run.
User-visible CLI/MCP output: not captured against a real provider; the change is catalog text only.
Remaining proof gaps: no real Hopper run; other providers untested.

Validation performed

npm run build:cached — passed
npm run test:focused -- tests/boundary/mcp/enhancedTools.traceFeatureCoverage.test.ts — 11 passed (1 failed on base, as above)
npm run check:fast — typecheck and lint passed
npm run docs:check — completed; no errors reported
npx oxfmt --check on changed files; git diff --check — clean
Not run: npm run check:pr, real-provider (Hopper/Ghidra/IDA) workflow
Toolchain note: local Node 24.20.0 / npm 11.19.0, not the pinned 24.18.0 / 11.16.0

Compatibility, safety, and release

Breaking changes or migration steps: none (description text only)
Real Hopper/Ghidra, browser, or OS coverage: none; simulated provider only, real provider not verified
Package or release metadata impact: none
Security, privacy, process, or containment review: not applicable

Author readiness
