codebase-intel-first
GitHub强制在代码任务（规划、审计、开发、调试）初期优先使用 jcodemunch 和 graphify 构建代码结构与依赖模型，避免低效的文件读取或 grep。明确发现与阅读的优先级，指导后续精准定位与修改。
Trigger Scenarios
任何涉及代码库的任务（规划、审计、审查、实现、重构、调试）
需要理解代码结构或模块关系时

"description": "MANDATORY orchestration step for ANY task that touches a codebase — planning, auditing, code review, implementing, refactoring, debugging, or \"help me understand X\". Run the jcodemunch symbol index + graphify dependency graph FIRST to build a structural mental model, BEFORE reading files, grepping, or spawning Explore agents. Resolves the precedence between lean-ctx (ctx_read\/ctx_search, which owns file I\/O) and code-intelligence retrieval (jcodemunch\/graphify, which own discovery\/understanding). Trigger at the START of every plan, audit, or coding task on easy and complex work alike — the graph\/index answer structural questions in one call instead of dozens of round-trips and never miss cross-module edges. Use together with jcodemunch-token-saver and graphify.",

Codebase Intel First
The orchestration layer over jcodemunch-token-saver (symbol index) and
graphify (dependency graph). Those two skills tell you HOW to use each tool.
This one tells you WHEN and IN WHAT ORDER — so code intelligence is the FIRST
move in every phase, not an afterthought.
The precedence rule (memorize this)
Discovering or understanding code → jcodemunch / graphify FIRST. Reading a file you already located, or any non-code file → lean-ctx
ctx_read.
lean-ctx's "ALWAYS use ctx_read instead of Read" mandate is about file I/O
efficiency. It does NOT mean "read files to discover structure." Discovery is
the graph's job. Never grep -r / find / ls -R across source to learn how
the code is shaped — query the graph.
Phase playbook — run these BEFORE anything else
Planning / "understand X" / architecture
mcp__graphify__graph_stats— size + shapemcp__graphify__god_nodes— entry points & most-connected modulesmcp__graphify__query_graph "<your question>"— NL structural querymcp__jcodemunch__get_repo_map/get_repo_outline— layoutmcp__jcodemunch__get_context_bundle/search_symbols "<name>"— the relevant code → Now write the plan. The graph IS your codebase map; don't rebuild it by reading dirs.
Auditing / review / dead-code / impact
mcp__jcodemunch__find_dead_code/get_dead_code_v2mcp__jcodemunch__get_blast_radius "<symbol>"mcp__jcodemunch__get_coupling_metrics/get_hotspotsmcp__jcodemunch__find_references/find_importers "<symbol>"mcp__graphify__god_nodes+get_neighbors "<node>"→ Complete + ranked. A grep-based audit silently misses cross-module call sites.
Implementing / changing code
mcp__jcodemunch__search_symbols "<name>"+get_symbol_source— locate preciselymcp__jcodemunch__find_references/find_importers— EVERY caller before a signature changemcp__jcodemunch__get_blast_radius "<symbol>"— before touching anything sharedmcp__graphify__get_neighbors "<file>"— downstream dependents → Then edit. Native Read/Grep on source is blocked during coding until jcodemunch is used.
Debugging
mcp__jcodemunch__get_call_hierarchy "<fn>"— callers + calleesmcp__jcodemunch__find_implementations/find_referencesmcp__jcodemunch__get_signal_chains— data/control flowmcp__graphify__shortest_path "<A>" "<B>"— connect two points
After the graph points you somewhere
Use lean-ctx to read the EXACT files/symbols surfaced:
ctx_read "<path>" mode=signatures|map|lines:N-Mfor the pinpointed filectx_readfor any doc / config /.env/ markdownctx_shellfor git / build / lint / test Read narrowly — jcodemunch already gave you byte-precise locations.
Freshness — do NOT rebuild unless told
systemd watch daemons + SessionStart guards keep the index/graph fresh. Rebuild ONLY when a guard prints STALE/MISSING:
- jcodemunch:
mcp__jcodemunch__index_folder({"path": "<root>", "incremental": true}) - graphify:
graphify update <root>(Bash, cheap, no LLM)
Red flags (you are doing it wrong)
| Thought | Correct move |
|---|---|
| "Let me grep the repo to find where X is" | mcp__jcodemunch__search_symbols "X" |
| "Let me read this whole file to understand it" | get_symbol_source / ctx_read mode=signatures |
| "Let me Explore-agent the architecture" | mcp__graphify__query_graph / god_nodes |
| "I'll just change this function" | find_references + get_blast_radius first |
| "ctx_read is mandatory so I'll read to discover" | ctx_read is for files you LOCATED; discover via the graph |
