AgentMap is a TypeScript/JavaScript repository mapping tool that identifies code dependencies with 100% precision using the actual TypeScript compiler, outperforming grep-based approaches by 40 percentage points. It provides both a CLI and MCP server for agents to query relevant code without context waste, operating entirely locally with no vector databases or external APIs.

agentmap

Stop your coding agent from reading the wrong files.

Ask "what breaks if I change this?" and grep hands back a pile where 40% of the files don't actually depend on it. agentmap answers the same question at 100% precision — measured, on public repos, reproducibly.

npx @raymondchins/agentmap --relates src/lib/auth.ts

Your agent re-learns your codebase every session, grepping to find what connects to what and burning tokens before it writes a line. agentmap gives it a queryable, PageRank-ranked import/symbol map instead — built with ts-morph, the real TypeScript compiler, so it resolves what string matching cannot.

Question agentmap git grep
What depends on this file? 100% precision, 99.2% recall 59.9% precision
Where is this symbol defined? 53.3% top-1, 93.3% top-3 32% top-1, 80% top-3
Tokens to find a definition ~2.4× fewer

n=42 dependents / n=75 definitions across zod, zustand and hono at pinned commits. Ground truth is derived at runtime by an independent resolver, not hand-authored. Re-run it yourself: npm run eval. Full method + per-repo numbers: EVAL.md.

Precision is the point: every wrong file your agent opens is context spent being misled. --relates returns the full blast radius, so it costs more tokens than a bare grep -l file list — and that trade is stated plainly in the eval, not hidden.

npm CI License: MIT node

One file, one runtime dependency (ts-morph, which bundles the TypeScript compiler — ~10 MB installed). No vector DB, no embedding API, no server. npx @raymondchins/agentmap --any <query> and you have a ranked answer.

Fully local — no network calls, no telemetry, no data leaves your machine. agentmap reads your code, writes a cache under .claude/agentmap/, and never phones home (there is not a single fetch/http call in the source). Your code is never sent anywhere.

⚠️ Always install the scoped name: @raymondchins/agentmap. npx agentmap (unscoped) runs an unrelated package by a different author — this project is @raymondchins/agentmap, and the scoped name is required in every install and command. npmjs.com/package/@raymondchins/agentmap


Quickstart

No install needed:

npx @raymondchins/agentmap --any <query>

…or run it directly from a checkout:

node agentmap.mjs --any <query>

The first run builds and caches the map to .claude/agentmap/map.json (add .claude/agentmap/ to .gitignore). Subsequent runs serve the cache when the tree is clean and HEAD is unchanged, and silently rebuild from disk when there are uncommitted .ts/.tsx/.js/... edits — so queries always reflect your in-flight work.

Run with no flag to build + print a one-line summary:

$ node agentmap.mjs
agentmap: 154 files | 4 features | top hub: lib/utils.ts (deg 52, pr 0.105171)

Benchmark

Every task you hand a coding agent starts with the same hidden step — find the relevant code. Here's the token cost of that step, reading raw files vs querying agentmap, on a real 154-file Next.js app (vercel/ai-chatbot). Every figure is captured tool output (node benchmark/bench.mjs <repo> at the pinned sha):

Context tokens the agent burns to answer each question — token est = chars/4, applied to both sides.

That's the agent reaching the same answer on 58× fewer tokens overall — and the pattern holds across zod (367 files, 99.2%) and taxonomy (125 files, 96.0%), peaking at 646× fewer on a single whole-repo map. Reproducible at pinned shas; full per-scenario tables in ./benchmark/RESULTS.md.

Methodology note: the 58× overall figure is dominated by the whole-repo-load scenario (Scenario F — 150 K vs 1 K tokens), which skews the combined ratio sharply upward. Excluding it, the per-task overall ratio on the same sample repo is approximately 32×. Both numbers are real; the headline captures the most common agent worst-case (repo-dump on session start), while the per-task average better represents typical individual queries. RESULTS.md has the full breakdown.

Fewer tokens, but are they the right tokens? Token efficiency is only half the story — a separate EVAL.md (npm run eval) scores retrieval accuracy against ground truth derived live from real repos (zod, zustand, hono). Headline: agentmap returns the symbol definition in the top 3 93.3% of the time (naive grep 80%) at ~2.4× fewer tokens, and identifies a module's dependents at 100% precision / 99.2% recall (grep 100% recall but 59.9% precision). Fixtures are pinned to exact commits, so those numbers are re-derivable rather than whatever upstream happened to look like the day they were taken. Honest tradeoffs and method in EVAL.md.

Speed: a cold build (parse + PageRank + symbol graph) takes ~1.2s; a warm cached query returns in ~0.1s (the lazy-loaded path added in 0.2.2) — the agent has a ranked answer back before it would have finished opening the first handful of files.

Honest notes: the win scales with the work — the small rows above (63%, 11%) are the floor, and a trivial single-file lookup can even cost more than cat+grep (taxonomy's file-import task hit −313%; we leave it in). Numbers measure context-token volume, not answer quality or wall-clock.


Why it's different

Many "repo context" tools are a photocopy: they dump your repository (or a slice of it) into the prompt once and walk away — the copy goes stale the moment you edit a file, and nothing makes the agent actually read it. agentmap is queryable and ranked instead: the agent interrogates it flag-by-flag rather than swallowing a dump.

But the real reason to reach for agentmap is accuracy. It's built on ts-morph — the actual TypeScript compiler — so its import graph resolves the things a text/tree-sitter scanner guesses at: tsconfig/jsconfig paths, vite/vitest/webpack resolve.alias, package.json Node #imports subpaths, and pnpm/npm/yarn workspace cross-package imports. It reports an edgeCoverage map-health signal and warns loudly when a repo's imports mostly don't resolve, so a broken map is never framed as success — and a separate EVAL.md scores retrieval accuracy against live ground truth. That compiler-grade precision on TS/JS is the wedge.

The self-refreshing side — a post-commit rebuild plus a PreToolUse hook that steers the agent to the map before it serial-greps — is genuinely useful, but it isn't unique: CodeGraph (colbymchenry/codegraph, ~62k★ (2026-07-26)) ships a native OS-event file watcher (FSEvents/inotify) with debounced auto-sync and an installer that auto-configures eight agent CLIs. agentmap's honest edge over the multi-language graph tools is narrower and sharper: TS/JS resolution the others approximate, with a published accuracy eval.

agentmap Aider repo map RepoMapper Repomix code2prompt
Ranking algorithm Personalized PageRank (file + symbol graphs) PageRank (graph ranking) Importance heuristics None (file order) None (file order)

Dependencies ts-morph only Python + tree-sitter stack Python + tree-sitter Node Rust binary
Install npx @raymondchins/agentmap pip install aider-chat pip install npx/global cargo/binary

What that table is not claiming: agentmap is TS/JS-only (the others are multi-language), and it's a file-level import graph, not a full call-site/reference resolver (see Scope & limitations). The differentiators are narrow and honest: (1) compiler-grade TS/JS resolution (aliases, vite/webpack, #imports, workspaces) with a published accuracy eval, and (2) the --any router. The agent-loop wiring is real and convenient but not unique — CodeGraph and others auto-sync and auto-configure agent CLIs too; we don't claim it as a moat.


The agent loop (staying current, staying used)

A common failure of repo-map tools: they build a beautiful map, and then the agent forgets it exists and greps anyway. A map the agent doesn't open is just dead weight.

agentmap closes that loop. Two hooks (in ./hooks/) do the work: the map refreshes itself after every commit, and the agent gets nudged to query it before it serial-greps. You wire it once — then it stays current on its own, and stays used.

This wiring is table stakes, not the moat — CodeGraph and other tools also auto-sync (via native OS file watchers) and auto-configure agent CLIs. agentmap ships it because it's genuinely useful; the actual point of agentmap is the compiler-grade TS/JS accuracy the map is built on.

1. Auto-refresh on commit

hooks/post-commit rebuilds .claude/agentmap/map.json after each commit, detached + silenced so it never slows the commit. It skips during rebase/merge/cherry-pick and no-ops if Node is missing.

The hooks ship inside the npm package. The simplest setup:

npx @raymondchins/agentmap --install-hooks

This copies hooks/post-commit into .git/hooks/, sets it executable, ensures .claude/agentmap/ is in .gitignore, and auto-wires the PreToolUse nudge hook into .claude/settings.json (merge-safe + idempotent) so map enforcement is on by default — no manual paste. Manual alternative for just the post-commit hook:

# from your repo root
cp hooks/post-commit .git/hooks/post-commit
chmod +x .git/hooks/post-commit

The hook resolves the builder to the installed package — node_modules/.bin/agentmap, a PATH agentmap binary verified to be @raymondchins/agentmap, then npx @raymondchins/agentmap. It never runs a repo-local ./agentmap.mjs unless you opt in with AGENTMAP_HOOK_ALLOW_LOCAL=1 (for developing agentmap itself), so an attacker-planted agentmap.mjs can't execute on your next commit.

2. Force the agent to use it — PreToolUse hook

hooks/agentmap-nudge.mjs is a non-blocking hook for Claude Code that covers both the Grep tool and raw Bash text-searchers (grep/rg/egrep/fgrep/ag/ack). When either looks like a dependency / who-imports / component-usage / reuse / where-is-symbol search, it injects a reminder steering the agent to agentmap --any first. It never denies the call, and stays silent for raw-string / Tailwind-class / lowercase-HTML-tag sweeps and for pipe-filtered commands like ps aux | grep node — so it's high-signal, not nagging.

Fires on: import/require/export/from '...' patterns, JSX component tags (<Hero, <ProviderCard), explicit intent words (where is, who imports, reuse, existing component), and — in both the Grep tool and the Bash branch — bare multi-hump PascalCase identifiers (ProviderCard, TopProviders) that almost always mean "where is this symbol / who uses it". The Bash branch additionally only fires when the searcher is the primary command (at the start, or after ;/&&); piped log-filters stay silent.

All four nudge/gate variants (this one, Codex, Gemini, OpenCode) also self-gate on project presence: since they ship at user/global scope too (plugin bundle, ~/.gemini, ~/.codex, ~/.config/opencode), they walk up from the tool call's cwd to the filesystem root looking for node_modules/@raymondchins/agentmap or a built .claude/agentmap/map.json before doing anything else, so a repo with no agentmap stays silent instead of nagging (or, for Codex, denying a grep it has no business denying).

--install-hooks writes both matchers into .claude/settings.json for you (merge-safe — preserves existing settings, won't duplicate on re-run). The single hook file dispatches internally on tool_name. For reference, or to wire it by hand:

{
  "hooks": {
    "PreToolUse": [
      {
        "matcher": "Grep",
        "hooks": [{ "type": "command", "command": "node ./hooks/agentmap-nudge.mjs" }]
      },
      {
        "matcher": "Bash",
        "hooks": [{ "type": "command", "command": "node ./hooks/agentmap-nudge.mjs" }]
      }
    ]
  }
}

That's the "forced to use it" in the tagline: the map stays current on its own, and the agent is steered to it the moment it reaches for a dependency-shaped grep or Bash search.

3. Agent skills (Cursor, Claude Code, Codex, OpenCode, Gemini, Antigravity, Copilot)

npx @raymondchins/agentmap --install-skill

…or grab just the skill (no agentmap flags) via the skills CLI — agentmap ships the skills/agentmap/SKILL.md layout it expects:

npx skills add raymondchins/agentmap

--install-skill copies packaged SKILL.md files and a Cursor rule (.cursor/rules/agentmap.mdc, alwaysApply: true) into the current repo or global agent directories. Paths follow each platform's official skill-directory conventions. Options:

agentmap --install-skill --platform cursor           # Cursor rule only (project)
agentmap --install-skill --platform claude           # .claude/skills/agentmap/SKILL.md
agentmap --install-skill --platform codex            # .codex/skills/ (project) or ~/.codex/skills/ (global)
agentmap --install-skill --platform opencode         # .opencode/skills/ (project) or ~/.config/opencode/skills/ (global)
agentmap --install-skill --platform gemini           # .gemini/skills/ (project); global ~/.gemini/skills/ (Windows global: ~/.agents/skills/)
agentmap --install-skill --platform antigravity      # .agents/skills/ (project) or ~/.gemini/config/skills/ (global)
agentmap --install-skill --platform copilot          # .copilot/skills/ or ~/.copilot/skills/
agentmap --install-skill --global --platform claude  # ~/.claude/skills/...
agentmap --install-skill --platform agents           # legacy .agents/skills/ (project or global); excluded from default `all`
agentmap --install-skill --dry-run                   # preview paths, no writes

--platform all installs: claude, cursor, codex, opencode, gemini, antigravity, copilot (not legacy agents).

Some platforms also get always-on docs and hooks in the same command:

--platform Skill Also installs (project) Global docs
gemini .gemini/skills/…/SKILL.md GEMINI.md + .gemini/settings.json BeforeTool nudge ~/.gemini/GEMINI.md
codex .codex/skills/…/SKILL.md AGENTS.md merge-safe <!-- agentmap:begin/end --> block ~/.codex/AGENTS.md
opencode .opencode/skills/…/SKILL.md AGENTS.md + .opencode/plugins/agentmap-nudge.js ~/.config/opencode/AGENTS.md

Codex and OpenCode share one repo-root AGENTS.md on project install. Existing content outside the marked block is preserved.

Pair with --install-hooks (Claude Code) or --mcp (Cursor MCP).

4. Claude Code plugin (one-command bundle)

Prefer the plugin over --install-skill/--install-hooks if you're on Claude Code and want the skill, the PreToolUse grep/Bash nudge, and the stdio MCP server in a single install that auto-updates:

# in Claude Code
/plugin marketplace add raymondchins/agentmap
/plugin install agentmap@agentmap

The plugin bundles: the packaged SKILL.md, the PreToolUse nudge (both the Grep tool and Bash text-searchers, via ${CLAUDE_PLUGIN_ROOT}), and the stdio MCP server (npx -y @raymondchins/agentmap --mcp, so ts-morph is fetched on demand — the plugin cache ships no node_modules).

One thing the plugin can't do: install the git post-commit hook. Claude Code plugins can't write into .git/hooks/, so the auto-refresh-on-commit still needs a one-time npx @raymondchins/agentmap --install-hooks in each repo (it also wires the nudge into .claude/settings.json, harmlessly redundant with the plugin's copy). Without it the map still rebuilds on any dirty query — you just lose the commit-time refresh.

Onboarding by platform

Enforcement isn't uniform — some CLIs get a live hook that actively steers grep to agentmap, some get an MCP server the agent can call, and some are docs-only (a skill/rule the agent may or may not consult). Honest matrix:

Platform Install Enforcement Known gaps
Claude Code /plugin install agentmap@agentmap (or --install-hooks) live hookPreToolUse nudge on Grep + Bash searchers non-blocking (never denies grep); bare-symbol Grep nudge requires the #3 hook fix
Gemini CLI --install-skill --platform gemini live hook.gemini/settings.json nudge fires on the AfterTool/systemMessage path (the earlier BeforeTool + additionalContext combo was silently dropped — fixed in #4)
OpenCode --install-skill --platform opencode log-only.opencode/plugins/agentmap-nudge.js writes to the log, does not inject context plugin can't steer the model; relies on the AGENTS.md block being read
Cursor --install-skill --platform cursor + .cursor/mcp.json (below) MCP + docsalwaysApply rule + the MCP server Cursor's own hooks aren't wired; the rule is advisory
Codex CLI --install-skill --platform codex live gate.codex/config.toml PreToolUse hook denies only high-confidence structural greps; allow-fallback for logs/pipes/non-TS-JS; AGENTMAP_CODEX_GATE=0 bypasses; needs a trusted dir + Codex hooks-GA
Copilot CLI --install-skill --platform copilot docs-only.copilot/skills/ same as Codex — no live hook yet

Cursor MCP — copy-paste .cursor/mcp.json (Cursor's --mcp wiring is a documented dead-end otherwise; drop this at your repo root):

{
  "mcpServers": {
    "agentmap": {
      "command": "npx",
      "args": ["-y", "@raymondchins/agentmap", "--mcp"]
    }
  }
}

Then Cursor exposes the 11 query tools (any, find, relates, map, hubs, features, feature, symbols, search, callers, calls). Run agentmap --doctor any time to see what's wired vs missing.

Uninstall

agentmap only writes files into your repo/home — remove them to fully uninstall. agentmap --doctor lists every path it wrote, and every docs merge lives inside an <!-- agentmap:begin/end --> (or # agentmap:begin/end) fence, so deleting just that block leaves the rest of your AGENTS.md / GEMINI.md intact.

Platform Remove
Claude Code .claude/skills/agentmap/ + the agentmap PreToolUse block in .claude/settings.json
Cursor .cursor/rules/agentmap.mdc + the agentmap entry in .cursor/mcp.json
Codex .codex/skills/agentmap/, the # agentmap:begin/end block in .codex/config.toml, .codex/hooks/agentmap-codex-nudge.mjs, and the fenced block in AGENTS.md
OpenCode .opencode/skills/agentmap/, .opencode/plugins/agentmap-nudge.js, the AGENTS.md block
Gemini .gemini/skills/agentmap/, .gemini/hooks/agentmap-nudge.mjs, the BeforeTool hook in .gemini/settings.json, the GEMINI.md block
All map cache rm -rf .claude/agentmap/; npm devDep npm rm @raymondchins/agentmap; the agentmap block in .git/hooks/post-commit

Troubleshooting

Symptom Cause / fix
features (0) --features only detects Next.js app/ routes; a TanStack src/routes/ repo legitimately shows 0. Use --map / --symbols instead.
Empty or wrong map Usually no tsconfig.json / resolvable aliases in the target repo, so no edges resolved — run agentmap --doctor and check edgeCoverage in --json.
Stale-looking results By design the map rebuilds from disk on a dirty tree / SHA mismatch. Force a rebuild by just running agentmap.
Codex/Gemini nudge never fires Codex's gate is opt-in — set [features] hooks = true in .codex/config.toml (AGENTMAP_CODEX_GATE=0 disables it). Gemini needs the BeforeTool hook that --install-skill writes.
Installed the wrong agentmap This is @raymondchins/agentmap (npm scope) — not the unrelated unscoped agentmap packages.
Cursor MCP tools missing --mcp doesn't auto-wire Cursor; add the copy-paste .cursor/mcp.json from the matrix above and restart Cursor.

The --any router

Don't want to learn eight flags? You don't have to. Throw anything at --any — a filename, a function, a feature, even a raw string — and it figures out what you meant, returning the first layer that hits:

--any <query>
   │
   ├─ 1. FILE     exact path → unique basename → unique substring
   ├─ 2. SYMBOL   exported name contains the query (across all files)
   ├─ 3. FEATURE  app/-router feature name contains the query
   └─ 4. CONTENT  live `git grep` (tracked + untracked) — never stale

Layers 1–3 read the cached structural map (fast, ranked). Layer 4 is a live disk read via git grep -F, so raw strings, copy, Tailwind classes, and config values the structural graph never indexes still resolve instead of coming up empty.

Symbol hit (query resolved to a symbol → full block):

$ node agentmap.mjs --any cn
[structure] 1 symbol, 0 feature match for "cn"
  lib/utils.ts → cn (FunctionDeclaration)

Ambiguous file hit (query matched multiple files → narrow it):

$ node agentmap.mjs --any utils
[structure] "utils" matched 3 files — narrow it:
  lib/utils.ts
  lib/db/utils.ts
  tests/prompts/utils.ts

Content fallback (no file/symbol/feature match → live git-grep):

$ node agentmap.mjs --any streamText
[content] 13 lines:
app/(chat)/api/chat/route.ts:8:  streamText,
app/(chat)/api/chat/route.ts:194:        const result = streamText({
artifacts/code/server.ts:1:import { streamText } from "ai";
artifacts/code/server.ts:18:    const { fullStream } = streamText({
artifacts/code/server.ts:40:    const { fullStream } = streamText({
artifacts/sheet/server.ts:1:import { streamText } from "ai";
artifacts/sheet/server.ts:11:    const { fullStream } = streamText({

Commands

Every snippet below is representative output (long lists trimmed) from running agentmap against the public 154-file Next.js repo vercel/ai-chatbot (sha 2becdb4).

--any <q> — the router (file → symbol → feature → live content)

See The --any router above. Default first move for any "where/what/who" question.

--find <q> — reuse-before-rebuild symbol search

Find every symbol whose name contains the query — exported symbols plus non-exported top-level declarations. Use it before writing a new util or component to check what already exists (a private helper counts as reusable too).

$ node agentmap.mjs --find Message
find "Message": 55 match
  hooks/use-messages.tsx → useMessages (FunctionDeclaration)
  lib/errors.ts → getMessageByErrorCode (FunctionDeclaration)
  lib/types.ts → messageMetadataSchema (VariableDeclaration)
  lib/types.ts → MessageMetadata (TypeAliasDeclaration)
  lib/types.ts → ChatMessage (TypeAliasDeclaration)
  lib/utils.ts → convertToUIMessages (FunctionDeclaration)
  lib/utils.ts → getTextFromMessage (FunctionDeclaration)
  tests/helpers.ts → generateTestMessage (FunctionDeclaration)
  app/(chat)/actions.ts → generateTitleFromUserMessage (FunctionDeclaration)
  …

--search <q> — BM25 lexical search for vague queries

When you don't know the exact symbol name — the query an agent actually types — --search ranks symbols by BM25 lexical relevance over split-identifier tokens (the symbol name, its file's path segments, feature, and kind), fused with file PageRank so a strong hit in an important file wins ties. No embeddings, no vector DB; the index is built into map.json. The same ranker is wired into --any as a rung that fires only when exact file/symbol matching found nothing, so exact routing is unchanged.

$ node agentmap.mjs --search "auth retry logic"
search "auth retry logic": 3 match
  src/authRetry.ts → retryWithBackoff (FunctionDeclaration)  [6.83]
  …

Stopwords (the, that, of, …) are dropped, so --search "the function that dedupes symbols" works. Also available as the search MCP tool.

--relates <path> — blast radius + transitive relevance

The file's own block (exports / imports / direct dependents) plus a random-walk relevance list (personalized PageRank on the bidirectional import graph) — the files most related to the target, transitively, not just its direct importers.

$ node agentmap.mjs --relates lib/db/schema.ts
relates: lib/db/schema.ts  (pr 0.073744)
exports (14): user(VariableDeclaration), User(TypeAliasDeclaration), chat(VariableDeclaration), Chat(TypeAliasDeclaration), message(VariableDeclaration), DBMessage(TypeAliasDeclaration), …
imports (0): —
dependents (21): hooks/use-active-chat.tsx, lib/types.ts, lib/utils.ts, components/chat/artifact.tsx, components/chat/message.tsx, lib/db/queries.ts, app/(chat)/api/chat/route.ts, …
related (random-walk relevance):
  lib/utils.ts (0.0476)
  lib/types.ts (0.0376)
  components/chat/artifact.tsx (0.0372)
  components/chat/icons.tsx (0.0264)
  components/chat/message.tsx (0.0237)
  lib/db/queries.ts (0.0225)
  app/(chat)/api/chat/route.ts (0.0218)
  …

For a file carrying a React Server Components directive prologue, the output adds one more line — boundary: 'use client' (client component) or boundary: 'use server' (server module/actions) (rsc: 'client' | 'server' in --json) — right after dependents. This is additive and optional: repos with no 'use client'/'use server' directives never see the line.

--callers <sym> — compiler-accurate call graph (experimental)

Who actually calls a symbol, resolved by the TypeScript language service (ts-morph findReferencesAsNodes) — not tree-sitter name-matching. This is symbol-level blast radius: a type-position mention (typeof foo), a re-export, a bare value reference (const x = foo), or a same-named private local in another file is a different symbol and is never mis-attributed. --in <path> disambiguates a name defined in more than one file (exported definitions win over same-named private locals); results are ranked by caller-file PageRank and capped.

$ node agentmap.mjs --callers getMessageByErrorCode
callers of getMessageByErrorCode  [lib/errors.ts]: 3 call sites
  app/(chat)/api/chat/route.ts:88 → POST
  lib/db/queries.ts:142 → saveMessage
  components/chat/message.tsx:57 → PureMessage

JSX counts as a call site. <Foo /> compiles to React.createElement(Foo, …) (classic runtime) or jsx(Foo, …) (automatic runtime) — either way it's an invocation, so a component's callers include everywhere it's rendered, not just plain foo() calls. <Foo.Bar /> resolves to Bar, not the Foo namespace; <Foo>...</Foo> counts once (the closing tag isn't a second call site); an intrinsic tag (<div>) resolves to nothing in-project and produces no edge.

$ node agentmap.mjs --callers Button
callers of Button  [components/ui/button.tsx]: 25 call sites
  components/ai-elements/message.tsx:93 → MessageAction
  components/ai-elements/message.tsx:263 → MessageBranchPrevious
  components/ui/sidebar.tsx:249 → SidebarTrigger
  components/ui/alert-dialog.tsx:158 → AlertDialogAction
  components/ui/dialog.tsx:72 → DialogContent
  …

Before 0.17.0, JSX wasn't a recognized call shape at all, so that same query returned 0 call sites — a plain rg '<Button' beat the tool outright. Captured on vercel/ai-chatbot at c2f8235; reproduce it by running the query against that commit.

A deliberate deep query: it lazily spins up the TS type-checker (a few seconds on a large repo) only when invoked — the map build and every other query never pay that cost, and nothing is persisted. Accurate on statically-resolvable calls; dynamic dispatch, reflection, and string-keyed access are beyond any static tool. Also available as the callers MCP tool.

--calls <sym> — outgoing call graph (experimental)

The companion to --callers: which in-project symbols a symbol invokes. Each call and new X() site inside its body is resolved by the type checker (getDefinitionNodes), which follows an imported / re-exported binding through to the real declaration — so a same-named local elsewhere is never confused for the imported one. node_modules and TypeScript built-ins (console.log, Array.map, …) are excluded; dynamic dispatch, computed member access, and higher-order callees are honestly skipped.

$ node agentmap.mjs --calls extractFacts
extractFacts calls  [agentmap.mjs]: 15 in-project targets
  agentmap.mjs:756 → makeProject (FunctionDeclaration)
  agentmap.mjs:944 → rel (VariableDeclaration)
  agentmap.mjs:952 → excluded (VariableDeclaration)

JSX counts as an outgoing call too, for the mirror-image reason: a component whose body is nothing but return <Container><Sidebar /></Container> has no CallExpression in it, so before this fix it reported zero outgoing calls even though it clearly depends on both. Each <Foo /> / <Foo>...</Foo> in the body now resolves to its target declaration the same way a plain call does — the printed (kind) is the target's own declaration kind (FunctionDeclaration, etc.), not "JSX", since resolution is unchanged, only call-site detection is:

$ node agentmap.mjs --calls AppSidebar
AppSidebar calls  [components/chat/app-sidebar.tsx]: 35 in-project targets
  components/ui/tooltip.tsx:21 → Tooltip (FunctionDeclaration)
  components/ui/tooltip.tsx:33 → TooltipContent (FunctionDeclaration)
  components/ui/sidebar.tsx:144 → Sidebar (FunctionDeclaration)
  components/ui/sidebar.tsx:379 → SidebarContent (FunctionDeclaration)
  …

Same repo and commit: this returned 6 targets before 0.17.0 — only the plain hook and helper calls — and 35 after, because the 29 components it renders now count too.

Same lazy, out-of-band model as --callers (builds a Project only on the query, nothing persisted). Also the calls MCP tool. JSX closes a real gap here — it doesn't change what's still out of reach: the node_modules/dynamic-dispatch/computed-member/higher-order limits above still apply.

Going transitive — --depth N. Both --callers and --calls accept --depth N (default 1, max 5) for an N-hop closure: --callers foo --depth 3 is the transitive blast radius ("everything that reaches foo, up to 3 hops"); --calls foo --depth 3 is the dependency cone ("everything foo pulls in"). It BFS-traverses the same single warm Project — no extra build — with cycle detection and node caps so a hub can't explode; each result is tagged with its depth and a via parent. --depth 1 is the default single-hop query.

$ node agentmap.mjs --callers leaf --depth 2
callers of leaf  [src/chain.ts]: 2 callers within depth 2
  src/chain.ts:2 → mid [depth 1]
  src/chain.ts:3 → top [depth 2]

--feature <name> — files that make up a feature

Resolves a Next.js app/-router feature to its file set, plus the external files that depend on it.

  app/(chat)/api/chat/[id]/stream/route.ts
external dependents (0): —

--features — list features by size

$ node agentmap.mjs --features
features (4):
  api (11 files)
  login (1 files)
  register (1 files)
  chat (1 files)

--hubs — most important files (PageRank)

The files that matter most, ranked by PageRank importance (raw dependent degree shown alongside).

$ node agentmap.mjs --hubs
agentmap: 154 files (sha 2becdb4)
hubs (PageRank importance):
  lib/utils.ts (deg 52, pr 0.105171)
  lib/db/schema.ts (deg 21, pr 0.073744)

--symbols [N] — top ranked symbols (Aider-style)

The most important individual symbols across the repo, ranked by the identifier graph (defaults to 30).

$ node agentmap.mjs --symbols 10
top 10 ranked symbols (Aider-style):
  0.109902  lib/utils.ts → cn (FunctionDeclaration)
  0.036013  lib/types.ts → ChatMessage (TypeAliasDeclaration)
  0.025686  components/chat/artifact.tsx → ArtifactKind (TypeAliasDeclaration)
  0.022461  lib/errors.ts → ChatbotError (ClassDeclaration)

--map [--tokens N] [--focus <path>] — token-budgeted ranked digest

The token-budgeted digest (Aider's killer feature): a ranked, files-and-symbols summary that fits a token budget. Default budget is 8192 (1024 with --focus). --focus <path> personalizes the ranking toward a file you're working on.

$ node agentmap.mjs --map --tokens 400
# agentmap (154 files, sha 2becdb4) — focus: global, budget ~400 tok

lib/utils.ts:
  cn (FunctionDeclaration)
  generateUUID (FunctionDeclaration)

lib/types.ts:
  ChatMessage (TypeAliasDeclaration)
  CustomUIDataTypes (TypeAliasDeclaration)
  ChatTools (TypeAliasDeclaration)
  Attachment (TypeAliasDeclaration)

components/chat/artifact.tsx:
  ArtifactKind (TypeAliasDeclaration)
  UIArtifact (TypeAliasDeclaration)
  Artifact (VariableDeclaration)

lib/errors.ts:
  ChatbotError (ClassDeclaration)
  ErrorCode (TypeAliasDeclaration)

lib/db/schema.ts:
  Document (TypeAliasDeclaration)
  Suggestion (TypeAliasDeclaration)
  DBMessage (TypeAliasDeclaration)

# ~387 tokens (14 files shown)

Focused on a working file — the ranking re-centers on what lib/db/queries.ts actually touches:

$ node agentmap.mjs --map --focus lib/db/queries.ts --tokens 350
# agentmap (154 files, sha 2becdb4) — focus: lib/db/queries.ts, budget ~350 tok

lib/utils.ts:
  cn (FunctionDeclaration)
  generateUUID (FunctionDeclaration)
  getDocumentTimestampByIndex (FunctionDeclaration)
  fetcher (VariableDeclaration)
  getTextFromMessage (FunctionDeclaration)
  convertToUIMessages (FunctionDeclaration)
  fetchWithErrorHandlers (FunctionDeclaration)
  sanitizeText (FunctionDeclaration)

lib/db/schema.ts:
  DBMessage (TypeAliasDeclaration)
  Suggestion (TypeAliasDeclaration)
  Document (TypeAliasDeclaration)
  Chat (TypeAliasDeclaration)
  User (TypeAliasDeclaration)
  chat (VariableDeclaration)
  document (VariableDeclaration)
  message (VariableDeclaration)

lib/errors.ts:
  ChatbotError (ClassDeclaration)
  ErrorCode (TypeAliasDeclaration)

# ~324 tokens (8 files shown)

--print — full map as JSON

Dumps the cached map (hubs, features, rankedSymbols, files) as one JSON object — for piping into other tools. Also includes a top-level fileCount.

$ node agentmap.mjs --print | jq '.hubs[0]'
"lib/utils.ts (deg 52, pr 0.105171)"

--export <mermaid|dot> — visualize the import graph

Serializes the file import graph (nodes = files, edges = imports, top-N by PageRank, with three light style tiers) as Graphviz DOT or Mermaid — paste straight into mermaid.live, a GitHub README mermaid block, or dot -Tsvg. --focus <path> scopes to a file's 1-hop neighborhood. It reads the cached map only (no ts-morph Project), and prints graph text to stdout
