Semantic code search and call-graph tracing. An agent skill from yoanbernabeu/grepai.

pydantic/pydantic-ai-harness

Gives an agent a quick map of a codebase's structure, dependencies, changes and handoffs, and tunes per-project config so the output stays code-first.

JordanCoin/codemap

Semantic code analysis via LSP. An agent skill from lsp-client/lsp-skill.

lsp-client/lsp-skill

Researches code with evidence: traces callers, imports and cross-repo links, diagnoses failures and reports findings with exact file and line references and a confidence label.

bgauryy/octocode

Create a new release for grepai. An agent skill from yoanbernabeu/grepai.

yoanbernabeu/grepai

A skill your agent uses when orienting within the Hermes Agent CN Desktop codebase, locating source files, understanding the Tauri+React architecture, finding Rust commands or frontend modules, or…

Eynzof/Hermes-CN-Desktop

Gives an agent working in a Go codebase a structural view through a local MCP server: call graphs, blast-radius and impact analysis, and bounded first-call exploration.

ozgurcd/gograph

Maps BiSheng's approval-center architecture to exact service files and methods, so a change to approval logic can be located without searching the whole repo.

dataelement/bisheng

Maps the NGINX Kubernetes Ingress Controller codebase: repository layout, architectural layers, layer-crossing rules and which files are generated.

nginx/kubernetes-ingress

Unified task execution protocol for Codex-only work. An agent skill from lili-luo/aicoding-cookbook.

lili-luo/aicoding-cookbook

Searches git repositories cloned locally under a sandbox folder to answer questions with cited links and complete code snippets.

This skill should be used when finding, tracing, or understanding code in a repository with SymDex available.

husnainpk/SymDex

Render the shape of code — module boundaries, the types that cross them, signatures, and a cited call graph — for code that already exists or a change about to be built.

citypaul/.dotfiles

Routes code exploration through trace-mcp's indexed dependency graph, using symbol search, outlines, call graphs and change-impact tools instead of Read, Grep and Glob.
