Recover concatenated descriptions in Claude Code 2.1.231 prompts - #949

Estimated code review effort: 4 (Complex) | ~45 minutes Mergeability Score: 🟡 Moderate · up to The PR improves recovery of assembled prompt descriptions, but the current implementation can expand conditional/template combinations without a cap and may resolve same-named variables from the wrong scope, causing slow extraction or incorrect prompt records; a reported lint error also needs correction before merge.

Both tests repeat the same six steps: create the temp directory, build
cli.jsandprompts.jsonpaths, write the fixture, runpromptExtractorPath, parse the JSON, and remove the temp directory. Only the fixture source and the assertions differ.A helper reduces the duplication and keeps each test focused on its assertions.

The test asserts exclusion of the short first literal only. The second literal at Line 73 is the long fragment that pushes the assembled value past the threshold. An assertion on it would catch a regression where the assembled-description pass starts accepting non-

Inline comments:
In `@tools/promptExtractor.js`:
- Around line 129-196: Update resolveStaticStringExpression to enforce a fixed
maximum variant count during TemplateLiteral, BinaryExpression, and
ConditionalExpression expansion, abandoning expansion when the cap is exceeded
while preserving enough information for the recognition check to determine
whether any variant reaches minLength. Avoid copying the entire nextSeen set at
every recursive step by reusing or tracking recursion state with lower
allocation overhead, while preserving cycle protection.
- Around line 735-737: Fix the no-unused-vars lint error in the
mergedResult.prompts mapping by removing the unused start and end destructuring
or applying the repository’s supported underscore-prefix convention; verify the
existing ESLint configuration before choosing the approach, and preserve the
returned rest objects.
- Around line 198-217: Make static binding collection and resolution scope-aware
instead of using one global name-keyed map. Update collectStaticStringBindings
and resolveStaticStringExpression so an Identifier resolves only to a
declaration in its enclosing scope chain, while preserving function-call
resolution and preventing unrelated-scope literals from entering
resolved.leaves.

Add the ToolSearch, device_bash, and computer_batch source literals that were omitted when their runtime descriptions were assembled from multiple strings. Preserve each literal as a separately patchable prompt record.

Why
Claude Code assembles some tool descriptions from several sibling literals. Short opening, conditional, and closing fragments were omitted from the 2.1.231 prompt snapshot even though they contribute to substantial runtime descriptions.
This left the ToolSearch data beginning mid-sentence with “This tool takes a query…” while omitting the opening that introduces deferred tools and the conditional notes explaining why an unfetched tool cannot be called. The same failure shape affected
device_bashandcomputer_batch.What changed
