+# Limit Pre-Push Typecheck Concurrency Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Limit the repository's Husky pre-push typecheck to three parallel Turbo tasks.
+
+**Architecture:** Modify only the pre-push hook to call the existing Turbo `typecheck` task graph with an explicit `--concurrency=3` argument. Keep the root package script and CI behavior unchanged.
+
+**Tech Stack:** POSIX shell, Husky, Bun, Turborepo 2.8.13
+
+## Global Constraints
+
+- The concurrency value is exactly `3`.
+- Only `.husky/pre-push` changes during implementation.
+- The root `typecheck` package script remains unchanged.
+- Validation must not execute the full typecheck workload.
+
+---
+
+### Task 1: Limit the pre-push typecheck
+
+**Files:**
+- Modify: `.husky/pre-push:20`
+- Test: static shell assertions and Turbo dry-run
+
+**Interfaces:**
+- Consumes: the existing Turborepo `typecheck` task graph.
+- Produces: a pre-push hook that schedules at most three Turbo tasks concurrently.
+
+- [ ] **Step 1: Run the failing static assertion**
+
+```bash
+grep -Fx 'bun turbo typecheck --concurrency=3' .husky/pre-push
+```
+
+Expected: exit status `1` because the hook currently contains `bun typecheck`.
+
+- [ ] **Step 2: Apply the minimal implementation**
+
+Replace:
+
+```sh
+bun typecheck
+```
+
+with:
+
+```sh
+bun turbo typecheck --concurrency=3
+```
+
+- [ ] **Step 3: Run the passing static assertions**
+
+```bash
+grep -Fx 'bun turbo typecheck --concurrency=3' .husky/pre-push
+! grep -Fx 'bun typecheck' .husky/pre-push
+```
+
+Expected: both assertions exit with status `0`.
+
+- [ ] **Step 4: Validate shell syntax and Turbo argument parsing**
+
+```bash
+sh -n .husky/pre-push
+bun turbo typecheck --concurrency=3 --dry=json >/tmp/opencode-typecheck-dry-run.json
+jq -e '.tasks | type == "array"' /tmp/opencode-typecheck-dry-run.json
+rm -f /tmp/opencode-typecheck-dry-run.json
+```
+
+Expected: all commands exit with status `0`; no `tsgo` typecheck workers are launched.
+
+- [ ] **Step 5: Commit the hook change**
+
+```bash
+git add -- .husky/pre-push
+git commit -m "fix: limit pre-push typecheck concurrency" -- .husky/pre-push
+```
+
+Expected: one commit containing only `.husky/pre-push`.

+# Limit pre-push typecheck concurrency
+
+## Problem
+
+The repository's Husky `pre-push` hook runs `bun typecheck`, which expands to `bun turbo typecheck`. On the two-CPU, 3.8 GiB server, Turbo launched ten `tsgo` workers while checking 35 packages. Those workers exhausted RAM and swap and triggered the OOM killer.
+
+## Decision
+
+Change only `.husky/pre-push` to invoke Turbo directly with a concurrency limit:
+
+```sh
+bun turbo typecheck --concurrency=3
+```
+
+This keeps the existing typecheck task graph while allowing at most three parallel tasks during a push. The global `typecheck` package script remains unchanged, so local and CI callers retain their current behavior.
+
+## Alternatives considered
+
+- Add `--concurrency=3` to the root `typecheck` package script. Rejected because it changes every caller, not only the problematic push hook.
+- Set `TURBO_CONCURRENCY=3` in the hook environment. Rejected because the effective limit is less visible than an explicit CLI argument.
+
+## Validation
+
+1. Before editing, verify the hook does not contain the required limited command.
+2. After editing, verify the hook contains exactly `bun turbo typecheck --concurrency=3` and no unrestricted `bun typecheck` invocation.
+3. Run the hook through `sh -n`.
+4. Run Turbo with `--dry` and `--concurrency=3` to validate argument parsing without starting package typechecks.
+
+## Out of scope
+
+This change does not alter systemd services, OpenCode memory limits, CI behavior, or the root `typecheck` script.
