fix(geminicli): generate subagents to .gemini/agents/ as native (not simulated) by lgaudez · Pull Request #1409 · dyoshikawa/rulesync

lgaudez · 2026-03-31T07:17:33Z

Summary

Fix Gemini CLI subagents output path: .gemini/subagents/ → .gemini/agents/ (where Gemini CLI actually expects them)
Make GeminiCliSubagent a native subagent (extends ToolSubagent directly) instead of simulated — no --simulate-subagents flag needed
Remove automatic injection of experimental.enableAgents into .gemini/settings.json — users should set this manually
Update docs note (dated 2026-04-01) to inform users to set "experimental": { "enableAgents": true } in .gemini/settings.json manually
Forward global param in fromRulesyncSubagent and fromFile for consistency with other native subagents
Update README/docs: geminicli subagents column 🎮 → ✅

Unrelated change included

.lintstagedrc.js: changed tsx scripts/sync-skill-docs.ts → node --import tsx/esm scripts/sync-skill-docs.ts. This was needed because the tsx CLI creates a Unix IPC socket at /tmp/tsx-*/...pipe which was blocked by the sandbox during development. Included here since it was required to run the pre-commit hook locally.

Test plan

Unit tests for GeminiCliSubagent updated to reflect native behavior (toRulesyncSubagent() now works)
E2E test: geminicli subagents generate to .gemini/agents/planner.md without --simulate-subagents
pnpm cicheck passes (174 test files, 4603 tests)

…rimental.enableAgents Gemini CLI expects subagent files in .gemini/agents/, not .gemini/subagents/. Also injects `experimental.enableAgents: true` into .gemini/settings.json when generating Gemini CLI subagents, which is required for the agents feature to work. Existing settings are preserved during injection. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Also fix lint-staged tsx invocation to use node --import tsx/esm to avoid IPC socket creation which is unnecessary for one-off script execution. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

- Guard settings injection behind toolFiles.length > 0 to avoid touching .gemini/settings.json when no subagents are actually generated - Wrap JSON.parse in try/catch with logger.warn fallback for malformed or JSONC settings files - Strengthen E2E test to assert exact mcpServers value (not just defined) - Add E2E test asserting other experimental flags are preserved on merge - Remove stale **/.gemini/subagents/ entry from .gitignore Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Add postGenerate hook to FeatureProcessor and DirFeatureProcessor base classes so tool-specific side effects can be encapsulated in the relevant processor rather than as string-switch cases in generate.ts. Move the experimental.enableAgents injection for Gemini CLI out of generateSubagentsCore() in generate.ts into SubagentsProcessor.postGenerate() where it belongs architecturally, consistent with how OpenCode handles its mode logic. Also clean up supportsSimulated meta flag — all entries are now false since the SimulatedSubagent instanceof check is the authoritative gate.

Remove this postGenerate everywhere. We want the user of rulesync to be able to say where he wants his subagents folder. Note that if subagents folder was used by rulesync, we should not break any behaviour they had

Solid refactoring overall — converting GeminiCliSubagent from SimulatedSubagent to a native ToolSubagent is clean and well-tested. The path change to .gemini/agents/ and the docs/README updates are consistent.

Two things worth addressing: fromRulesyncSubagent and fromFile both skip destructuring/forwarding the global parameter, which every other native subagent (ClaudeCode, Cursor, Copilot) does. While supportsGlobal is false for geminicli today, the inconsistency will cause a subtle bug if global support is ever added.

The .lintstagedrc.js change (tsx -> node --import tsx/esm) seems unrelated to this PR's scope — might be worth calling out in the description or splitting into its own commit.

No security concerns found.

src/features/subagents/geminicli-subagent.ts

+  static fromRulesyncSubagent({
+    baseDir = process.cwd(),
+    rulesyncSubagent,
+    validate = true,


Missing global = false destructuring here. All other native subagents (ClaudecodeSubagent, CursorSubagent, CopilotSubagent) destructure global from ToolSubagentFromRulesyncSubagentParams and forward it to getSettablePaths({ global }) and the constructor. Without it, if global support is ever added for geminicli, this method will silently ignore the flag.

Suggested change

validate = true,

static fromRulesyncSubagent({

baseDir = process.cwd(),

rulesyncSubagent,

validate = true,

global = false,

}: ToolSubagentFromRulesyncSubagentParams): ToolSubagent {

+  static async fromFile({
+    baseDir = process.cwd(),
+    relativeFilePath,
+    validate = true,


Same issue as fromRulesyncSubagent — global is not destructured or forwarded to getSettablePaths(). Other native subagents pass this.getSettablePaths({ global }) here.

Suggested change

validate = true,

static async fromFile({

baseDir = process.cwd(),

relativeFilePath,

validate = true,

global = false,

}: ToolSubagentFromFileParams): Promise<GeminiCliSubagent> {

const paths = this.getSettablePaths({ global });

This change from tsx to node --import tsx/esm looks unrelated to the geminicli subagents fix. Consider splitting it into its own commit or at least noting it in the PR description so it does not get lost in the diff.

Regarding the .lintstagedrc.js change: this was introduced because the tsx CLI binary creates a Unix IPC socket at /tmp/tsx-*/...pipe during execution. In my local environment (Claude Code's sandbox), access to /tmp/ is restricted, which caused the pre-commit hook to fail on every commit attempt.

Switching to node --import tsx/esm avoids the socket entirely and unblocked the hook for me. That said, this is specific to my sandbox setup — tsx works fine in a normal terminal and the change has no effect for other contributors.

Happy to revert it if you'd prefer to keep the diff clean. Alternatively, node --import tsx/esm is slightly more explicit and avoids spawning an extra subprocess, so it could be kept as a minor improvement. Your call.

+    return new GeminiCliSubagent({
+      baseDir,
+      relativeDirPath: paths.relativeDirPath,
+      relativeFilePath: basename(relativeFilePath),


fromFile() reads the subagent from relativeFilePath (which may include subdirectories), but then stores only basename(relativeFilePath) on the instance. This makes the resulting GeminiCliSubagent no longer represent the actual file path that was loaded (e.g., getFilePath()/logging will point to .gemini/agents/nested-agent.md even if the file was .gemini/agents/subdir/nested-agent.md). Consider preserving the full relativeFilePath like other native subagents (e.g. CursorSubagent.fromFile) or, if Gemini CLI truly disallows subdirectories, reject/normalize earlier and keep behavior consistent across load/write paths.

        baseDir: testDir,
-        relativeDirPath: ".gemini/subagents",
+        relativeDirPath: ".gemini/agents",


Tests pass filesystem paths as hardcoded POSIX strings (e.g. ".gemini/agents"). Since the implementation uses join() for these paths (and the project aims to support Windows paths), these should ideally use join(".gemini", "agents") as well to avoid platform-dependent behavior.

Suggested change

relativeDirPath: join(".gemini", "agents"),
