Tool Reference

Tool	Purpose	Key Attributes & Safety
read_file	Read line-numbered file contents or slices	Supports offset and limit to prevent massive token overruns
edit_file	Surgical exact-string code replacements	Precise match replacement avoids hallucinations in large files
write_file	Full file creation or replacement	Recursively creates parent directories automatically
list_directory	Immediate directory file inspection	Honors .gitignore exclusion rules by default
glob	Find files matching wildcard patterns	Cross-platform fast file path matching
grep	Literal or regex pattern search	Supports -C, -A, -B context lines and file type filters
run_command	Execute shell commands in native bash	Idle timeout safeguards and background task management
code_explore	Semantic code graph & symbol exploration	Bilingual thesaurus matching for deep cross-module reference tracing
repo_map	Full repository AST symbol outline tree	Token-budgeted AST symbol hierarchy
task	Dispatch parallel subagents	Read-only explore and path-scoped worker subagents
request_user_input	Interactive user questions	Single/multiple choice and text collection dialogs

Semantic Code Graph & Bilingual Thesaurus (code_explore)

In enterprise codebases, basic grep queries often produce overwhelming noise and false positives. JeikCode features semantic AST-driven code intelligence:

1. Bilingual Thesaurus Alignment

JeikCode incorporates a bilingual synonym thesaurus. When querying with domain concepts (e.g. "how is authentication validated?"), the engine cross-references English code symbols (e.g. AuthClaims, verify_token) and maps call hierarchies accurately.

2. Precise Reference & Call Graph Resolution

Using AST-level parsing, code_explore isolates:

• Symbol definitions;
• Exact read and write call sites;
• Full upstream and downstream call graphs.
