From b0674550c6783f69eaba5cfbd615b6f7b89c4ccc Mon Sep 17 00:00:00 2001 From: Ahmed Abushagur Date: Wed, 25 Mar 2026 10:42:09 -0700 Subject: [PATCH] feat: recursive spawn (--beta recursive) (#2978) * feat: add recursive spawn (--beta recursive) Enables VMs to spawn child VMs. When --beta recursive is active: - Injects SPAWN_PARENT_ID, SPAWN_DEPTH, SPAWN_BETA=recursive into .spawnrc - Installs spawn CLI on the VM via install.sh - Delegates cloud + OpenRouter credentials to the VM - Tracks parent_id and depth on SpawnRecord for tree relationships - Adds `spawn tree` command for full recursive tree view - Adds `spawn history export` for pulling child history via SSH - Adds `spawn list --json` and `spawn list --flat` flags - Adds tree rendering in `spawn list` when parent-child relationships exist - Adds cascade delete support in delete.ts - Adds mergeChildHistory() for backward-pass history sync Co-Authored-By: Claude Opus 4.6 (1M context) * docs: add recursive spawn to README Add --beta recursive to beta features table, new commands (spawn tree, spawn history export, spawn list --flat/--json) to commands table, and a dedicated Recursive Spawn section with usage examples for tree view and cascade delete. Co-Authored-By: Claude Opus 4.6 (1M context) * test: add cmdTree coverage tests to fix mock test CI The CI coverage threshold (90% functions, 80% lines) was failing because tree.ts had 0% coverage. Added tests that exercise cmdTree with empty history, tree rendering, JSON output, flat records, and deleted/depth labels. tree.ts now has 100% coverage. Co-Authored-By: Claude Opus 4.6 (1M context) * fix(security): validate cloudName and use valibot in pullChildHistory - Add cloudName validation against ^[a-z0-9-]+$ to prevent command injection in delegateCloudCredentials - Export SpawnRecordSchema from history.ts and replace loose type guard with valibot schema validation in pullChildHistory - Resolve merge conflicts with main (include both docker and recursive beta features) Agent: pr-maintainer Co-Authored-By: Claude Sonnet 4.5 * test: add installSpawnCli and delegateCloudCredentials coverage Export and test installSpawnCli (success + timeout failure paths) and delegateCloudCredentials (no creds, with creds, write failure, mkdir failure paths) to improve orchestrate.ts function coverage. Co-Authored-By: Claude Opus 4.6 (1M context) * fix: gritQL rule false positives and delete.ts coverage - use TsAsExpression() AST node instead of backtick pattern to avoid matching import aliases as type assertions - export and test findDescendants() and pullChildHistory() to bring delete.ts line coverage above the 35% threshold - add 8 new tests for descendant finding and history pull edge cases Co-Authored-By: Claude Opus 4.6 (1M context) --------- Co-authored-by: Claude Opus 4.6 (1M context) Co-authored-by: B <6723574+louisgv@users.noreply.github.com> Co-authored-by: A <258483684+la14-1@users.noreply.github.com> --- README.md | 36 +- lint/no-type-assertion.grit | 2 +- packages/cli/package.json | 2 +- .../cli/src/__tests__/recursive-spawn.test.ts | 724 ++++++++++++++++++ packages/cli/src/commands/delete.ts | 112 ++- packages/cli/src/commands/index.ts | 9 +- packages/cli/src/commands/list.ts | 93 ++- packages/cli/src/commands/run.ts | 12 + packages/cli/src/commands/tree.ts | 111 +++ packages/cli/src/history.ts | 43 +- packages/cli/src/index.ts | 26 +- packages/cli/src/shared/orchestrate.ts | 106 ++- 12 files changed, 1261 insertions(+), 15 deletions(-) create mode 100644 packages/cli/src/__tests__/recursive-spawn.test.ts create mode 100644 packages/cli/src/commands/tree.ts diff --git a/README.md b/README.md index 0cdf08fd..96e156f4 100644 --- a/README.md +++ b/README.md @@ -61,7 +61,12 @@ spawn delete -c hetzner # Delete a server on Hetzner | `spawn list ` | Filter history by agent or cloud name | | `spawn list -a ` | Filter history by agent | | `spawn list -c ` | Filter history by cloud | +| `spawn list --flat` | Show flat list (disable tree view) | +| `spawn list --json` | Output history as JSON | | `spawn list --clear` | Clear all spawn history | +| `spawn tree` | Show recursive spawn tree (parent/child relationships) | +| `spawn tree --json` | Output spawn tree as JSON | +| `spawn history export` | Dump history as JSON to stdout (used by parent VMs) | | `spawn fix` | Re-run agent setup on an existing VM (re-inject credentials, reinstall) | | `spawn fix ` | Fix a specific spawn by name or ID | | `spawn link ` | Register an existing VM by IP | @@ -149,8 +154,37 @@ spawn claude gcp --beta tarball --beta parallel | `tarball` | Use pre-built tarball for agent install (faster, skips live install) | | `images` | Use pre-built cloud images/snapshots (faster boot) | | `parallel` | Parallelize server boot with setup prompts | +| `recursive` | Install spawn CLI on VM so it can spawn child VMs | -`--fast` enables all three. +`--fast` enables `tarball`, `images`, and `parallel` (not `recursive`). + +#### Recursive Spawn + +Use `--beta recursive` to let spawned VMs create their own child VMs: + +```bash +spawn claude hetzner --beta recursive +``` + +What this does: +- **Installs spawn CLI** on the remote VM +- **Delegates credentials** (cloud + OpenRouter) so child VMs can authenticate +- **Injects parent tracking** (`SPAWN_PARENT_ID`, `SPAWN_DEPTH`) into the VM environment +- **Passes `--beta recursive`** to children so they can also spawn recursively + +View the spawn tree: +```bash +spawn tree +# spawn-abc Claude Code / Hetzner 2m ago +# ├─ spawn-def Codex CLI / Hetzner 1m ago +# └─ spawn-ghi OpenClaw / Hetzner 30s ago +# └─ spawn-jkl Claude Code / Hetzner 10s ago +``` + +Tear down an entire tree: +```bash +spawn delete --cascade # Delete a VM and all its children +``` ### Without the CLI diff --git a/lint/no-type-assertion.grit b/lint/no-type-assertion.grit index b14c2ea3..7b1740f9 100644 --- a/lint/no-type-assertion.grit +++ b/lint/no-type-assertion.grit @@ -1,6 +1,6 @@ language js(typescript) -`$value as $type` as $expr where { +TsAsExpression() as $expr where { ! $expr <: `$_ as const`, ! $expr <: JsNamedImportSpecifier(), register_diagnostic(span=$expr, message="Type assertions (`as`) are banned.
