perf: run the locally installed CLI from agent hooks by LadyBluenotes · Pull Request #283 · TanStack/intent

LadyBluenotes · 2026-09-12T02:11:45Z

Summary

The biggest remaining cost in the agent workflow was not in the CLI at all. The generated hook runner builds the session-start catalog by running the package-manager runner through a shell:

npx @tanstack/intent@latest list --json --no-notices

npx resolves the latest tag against the registry on every invocation. Measured on Windows: 1.5 to 3.8 s per call, 1.4 s even with --offline, and 1.25 s for npx intent with the bin already installed locally; pnpm dlx is 350 to 750 ms. The CLI itself takes ~100 to 200 ms. The same runner string is what the catalog tells the agent to use for every load.

This PR changes the generated runner:

Resolve the local install first. Walk up from the event cwd looking for node_modules/@tanstack/intent/package.json, read its bin, and execute it with process.execPath and no shell. Fall back to the package-manager runner only when there is no local install, so projects that never installed Intent behave exactly as before.
Suggest the bin shim for loads. When node_modules/.bin/intent exists, the catalog says node_modules/.bin/intent load <package>#<skill> (path relative to the event cwd) instead of the runner. parseIntentInvocation now accepts a path-prefixed intent (node_modules/.bin/intent, ./node_modules/.bin/intent, ../../node_modules/.bin/intent, backslashes too) so the edit gate recognizes it; my-intent load still does not match.
Ignore an empty event cwd instead of handing it to spawnSync.

Existing hooks keep working; re-running intent hooks install regenerates the runner with the new behavior (documented in the changeset and docs/cli/intent-hooks.md).

Measurements

Session-start hook, end to end, on a project with 6 intent-enabled packages and 23 skills (Windows, warm):

Runner	Hook wall time
package-manager runner (`npx @tanstack/intent@latest`)	~600 ms best case, 1.5 to 3.8 s typical
local CLI via `process.execPath` (this PR)	~300 ms, of which `list` itself is ~200 ms

The suggested load command drops from the same npx cost to ~150 ms via the bin shim.

Summary by CodeRabbit

New Features
- Session-start catalogs now use the locally installed Intent CLI when available, significantly reducing startup time.
- Suggested load commands now reference the project’s local CLI shim when available.
- The system continues to fall back to package-manager commands when no local CLI or shim is found.
- Intent commands work with common relative, nested, and Windows-style local binary paths.
Chores
- Reinstall hooks with intent hooks install to receive the updated runner behavior.

📝 Walkthrough

Walkthrough

The hook runner now prefers a project-local Intent CLI for catalog loading, uses its matching bin shim for load commands when available, and falls back to the configured package-manager command. Invocation parsing and integration tests cover local shim paths and fallback behavior.

Changes

Local CLI catalog flow

Layer / File(s)	Summary
Local CLI resolution and catalog generation `packages/intent/src/hooks/install.ts`, `packages/intent/tests/hooks-install.test.ts`	The hook runner resolves the local CLI once, runs it directly when available, derives load commands from the same installation, and retains the package-manager fallback. Integration tests cover workspace resolution, missing shims, and local CLI execution.
Local command invocation parsing `packages/intent/src/hooks/policy.ts`, `packages/intent/tests/hooks.test.ts`	Invocation parsing accepts path-prefixed `intent` bin commands. Tests cover POSIX, nested, Windows, list, and non-matching command forms.
Hook behavior documentation and release note `.changeset/hooks-local-cli.md`	The changeset documents local CLI execution, fallback commands, local shim suggestions, edit-gate parsing, and hook reinstallation requirements.

Priority: ⬇️ Low

Estimated code review effort: 3 (Moderate) | ~20 minutes

The session-start hook built its skill catalog by running the package-manager runner (`npx @tanstack/intent@latest list ...`, or the pnpm/yarn/bun equivalent) through a shell. npx resolves the `latest` tag against the registry on every invocation, so each session start cost one to four seconds before the CLI even started (~1.4s even with `--offline`), and the same runner was suggested to the agent for every `load`. The generated runner now resolves `@tanstack/intent` from the project's node_modules (walking up from the event cwd), and when found executes its bin with the current Node binary and no shell. It falls back to the package-manager runner only when there is no local install. The catalog suggests `node_modules/.bin/intent load <package>#<skill>` when that shim exists, and the invocation parser accepts a path-prefixed `intent` so the edit gate recognizes it. An empty event cwd now falls back to process.cwd() instead of being passed to spawn. Measured on a project with 6 intent-enabled packages: session-start hook 300ms with the local CLI versus 600ms-3.8s through npx.

The catalog could be built from @tanstack/intent resolved in a parent node_modules while the suggested load command pointed at a nearer, unrelated .bin/intent shim. resolveLocalIntentCli now returns the node_modules directory it found the package in, and the shim is looked up there only; without one the runner command is suggested. Docs and changeset state that condition. Tests cover a nested workspace with a stray shim and a local install without a shim.

Companion to #283, which makes the generated hook runner execute the project's installed @tanstack/intent CLI directly and suggest the node_modules/.bin/intent shim for loads.

+'@tanstack/intent': patch
+---
+
+Make agent hooks fast when `@tanstack/intent` is installed in the project. The session-start catalog previously ran `npx @tanstack/intent@latest list` (or the pnpm, yarn, or bun equivalent), which resolves the package against the npm registry on every session start and took one to four seconds; the runner now executes the locally installed CLI directly with the current Node binary, which takes about a tenth of a second, and falls back to the package-manager runner only when there is no local install. When that installation also has a `node_modules/.bin/intent` shim, the catalog suggests `node_modules/.bin/intent load <package>#<skill>` for loads (otherwise it keeps suggesting the package-manager runner), and the edit gate recognizes that form. Reinstall hooks with `intent hooks install` to pick up the new runner.


🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Align the performance claim with the measured result.

Line 5 says local execution takes about one tenth of a second. The PR measurement reports approximately 300 ms. Update the release note to use the measured value or a non-specific performance claim.
