Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (12)

analyze_impactread-onlyReturn bounded reverse-caller impact for one exact compiler symbol.
find_referencesread-onlyReturn semantic static references to one exact compiler symbol.
find_symbolread-onlyResolve a symbol name to deterministic ranked compiler symbol candidates; safely reports ambiguity.
get_capabilitiesread-onlyReturn Semantic Reader capabilities, limits, billing and discovery facts.
get_definitionread-onlyReturn the compiler-resolved declaration for one supplied-file symbol.

get_importersread-onlyReturn supplied files that statically import one target file.
get_importsread-onlyReturn static imports made by one supplied file.
get_symbol_contextread-onlyReturn bounded definition/callers/callees context; references or impact request paid depth.
get_typeread-onlyReturn TypeScript type facts and call/construct signatures for one declaration.
open_snapshotread-onlyStore supplied source files ephemerally and return an opaque snapshot handle for reuse.
query_coderead-onlyFree navigation for symbols, callers, callees or function facts.
