Use this any time\n  you (the coding agent) need to orient in an unfamiliar or large codebase before making a\n  change: the user says \"help me understand this codebase\", \"what's load-bearing here\",\n  \"what would break if I change X\", \"who calls this\", \"map out this project's architecture\",\n  or you're about to touch code you haven't read yet and want to know what matters before\n  scanning everything by hand. This is the same extractor `wiki-update` Step 3b uses\n  internally — this skill exposes it directly so any agent session can call it on demand,\n  not just during a wiki sync.\n---\n\n# Code Understand — On-Demand Architecture Focus Map\n\nYou are about to work in a codebase you don't fully know yet. Instead of grepping around or\nreading files at random, ask the local extractor for a **focus map**: the ranked symbols the\narchitecture hangs on, each with a `file:line` citation and evidence type. Read only what it\npoints at — this is a map, not a substitute for reading the actual code it cites.\n\n## When to reach for this\n\n- Before editing an unfamiliar module — see what calls it and what it calls before changing\n  its shape.\n- The user asks \"how does X work\", \"what's the impact of changing Y\", \"who else uses this\n  function\" for a codebase, not the wiki.\n- You're about to do a large refactor and want a ranked list of load-bearing files instead of\n  reading the whole tree.\n- You already have a diff or a set of changed files and want to know their blast radius before\n  finishing the change.\n\nNot for: summarizing what a project *does* for the wiki (that's `wiki-update` Step 3b, which\ncalls this same command as part of a bigger sync flow) — use this skill directly only when you\nneed the focus map for your own immediate work, not to persist knowledge.\n\n## Running it\n\n```bash\nobsidian-wiki code-understand --project <dir> [--backend auto|builtin|codegraph] \\\n    [--changed <file>...] [--since <sha>] [--max-symbols N] [--pretty]\n```\n\n- `--project` — defaults to the current directory.\n- No `--changed`/`--since` — seeds from every tracked file (full-project scan).\n- `--changed <file>` (repeatable) — seed from specific files you already know are relevant\n  (e.g. files in the diff you're about to make).\n- `--since <sha>` — seed from everything changed since a git ref (e.g. `--since HEAD~5` or a\n  base branch).\n- `--backend` — `auto` (default) uses CodeGraph when installed, falls back to the builtin\n  extractor otherwise; force `builtin` for the dependency-free path, or `codegraph` to require\n  the enhanced backend (fails loudly if it's not installed rather than silently degrading).\n- `--max-symbols` — cap the focus map size (default 50); keep this small for a quick\n  orientation pass, raise it for a thorough one.\n\n**GUARD:** if the command is unavailable or errors, skip it and fall back to your normal\nexploration (grep/read) — this is an accelerant, not a dependency. Don't block work on it.\n\n## Reading the output\n\n1. **Evidence type matters.** When `backend: codegraph`, focus-map entries are structural\n   facts (real call-graph edges) — cite them directly. When `backend: builtin`, `defines`/\n   `imports`/`changed-file` entries are facts, but `rg-reference` entries are text-match\n   evidence only — open the file and confirm before treating it as a real relationship.\n2. **Open what it cites, nothing else first.** The focus map tells you *where* to read; it\n   never contains source bodies. Go read those `file:line` locations before forming an opinion\n   on the architecture.\n3. **Cite it in your own output.** If you explain the architecture back to the user or write\n   it into a PR description/commit message, keep the `(file:lines)` citations from the focus\n   map or from the source you opened — don't assert structure without a pointer to it.\n4. **It's a cache, not a deliverable.** Never write the raw JSON or `.codegraph/` into the\n   wiki vault, a PR description, or committed docs — it's a disposable sidecar in the project\n   repo (git-ignored). Re-run it fresh next time rather than treating old output as durable.\n\n## If CodeGraph isn't installed\n\n`auto`/`builtin` still work with zero setup (uses the regex AST extractor + `rg`). If you want\nthe enhanced cross-file call-graph evidence and the user is fine with installing something:\n\n```bash\nnpm install -g @colbymchenry/codegraph\n```\n\nor point `CODE_UNDERSTANDING_CODEGRAPH_BIN` at an existing binary. Never install without the\nuser's go-ahead — ask first, then re-run the command.\n\nCheck `obsidian-wiki doctor --project <dir>` for the `code-understanding.*` capability lines\n(`builtin`, `rg`, `codegraph`, `codegraph-index`, `codegraph-fresh`, `codegraph-gitignore`) to\nsee what's available before deciding which backend to request explicitly.\n","tagline":"Build a ranked, citation-backed focus map of a codebase — the files and symbols an architecture actually hangs on — using CodeGraph when available and a dependency-free builtin (regex AST extraction + `rg` cross-file references) otherwise.
