bin/opencode crashes on first run: require is not defined in ESM scope

Problem

packages/opencode/bin/opencode uses bare require("child_process") on line 3,
but packages/opencode/package.json declares "type": "module" — so the launcher
is parsed as ESM and dies on first run with:

ReferenceError: require is not defined in ESM module scope

Every invocation of the opencode CLI is affected, including --version — the
crash happens at module top level, before any command handling runs.

Approach

Swap the bare require for a namespace import from node:child_process, keeping
the rest of line 3 (and lines 4–5) untouched:

-const childProcess = require("child_process")+import childProcess from "node:child_process"

Minimal one-line patch; no behavior change beyond the launcher actually starting.

Acceptance Criteria

  • node packages/opencode/bin/opencode --version runs without a ReferenceError
  • node --check packages/opencode/bin/opencode passes (valid ESM)
  • No other lines of the bin script are modified

Testing Decisions

  • Reuse-first: check for an existing ESM-interop helper (createRequire idiom)
    before hand-rolling — per the constraints skill, never invent what a helper carries.

Key Decisions

  • Namespace default import (import childProcess from "node:child_process") over
    createRequire(import.meta.url) — the default import is the smaller diff and
    matches how the file's other imports are written.

Constraints & Invariants

  • "type": "module" in packages/opencode/package.json must remain true (invariant).
  • Do not reformat or touch lines 4–5 of the bin script.

Prior Art

  • packages/opencode/src/index.ts — the launcher's import block, written in ESM style.

Source

  • Root cause found in a live verification run (2026-09-01); node --check + --version
    confirmed the ESM parse failure before this brief was drafted.

                  Testing Decisions
                  • Reuse-first: check for an existing ESM-interop helper (createRequire idiom)
                    
before hand-rolling — per the constraints skill, never invent what a helper carries.
                  Key Decisions
                  • Namespace default import (import childProcess from "node:child_process") over
                    createRequire(import.meta.url) — the default import is the smaller diff and
                    
matches how the file's other imports are written.
                  Constraints & Invariants
                  • "type": "module" in packages/opencode/package.json must remain true (invariant).
                  • Do not reformat or touch lines 4–5 of the bin script.
                  Prior Art
                  • packages/opencode/src/index.ts — the launcher's import block, written in ESM style.
                  Source
                  • Root cause found in a live verification run (2026-09-01); node --check + --version
                    
confirmed the ESM parse failure before this brief was drafted.

                      bin/opencode crashes on first run: require is not defined in ESM scope
                      Problem
                      packages/opencode/bin/opencode uses bare require("child_process") on line 3,
                      
but packages/opencode/package.json declares "type": "module" — so the launcher
                      
is parsed as ESM and dies on first run with:
                      ReferenceError: require is not defined in ESM module scope

                      Every invocation of the opencode CLI is affected, including --version — the
                      
crash happens at module top level, before any command handling runs.
                      Approach
                      Swap the bare require for a namespace import from node:child_process, keeping
                      
the rest of line 3 (and lines 4–5) untouched:
                      -const childProcess = require("child_process")+import childProcess from "node:child_process"
                      Minimal one-line patch; no behavior change beyond the launcher actually starting.
                      Acceptance Criteria
                      • node packages/opencode/bin/opencode --version runs without a ReferenceError
                      • node --check packages/opencode/bin/opencode passes (valid ESM)
                      •  No other lines of the bin script are modified
                      Testing Decisions
                      • Reuse-first: check for an existing ESM-interop helper (createRequire idiom)

is parsed as ESM and dies on first run with:
                              ReferenceError: require is not defined in ESM module scope

                              Every invocation of the opencode CLI is affected, including --version — the
                              
crash happens at module top level, before any command handling runs.
                              Approach
                              Swap the bare require for a namespace import from node:child_process, keeping
                              
the rest of line 3 (and lines 4–5) untouched:
                              -const childProcess = require("child_process")+import childProcess from "node:child_process"
                              Minimal one-line patch; no behavior change beyond the launcher actually starting.
                              Acceptance Criteria
                              • node packages/opencode/bin/opencode --version runs without a ReferenceError
                              • node --check packages/opencode/bin/opencode passes (valid ESM)
                              •  No other lines of the bin script are modified
                              Testing Decisions
                              • Reuse-first: check for an existing ESM-interop helper (createRequire idiom)
                                
before hand-rolling — per the constraints skill, never invent what a helper carries.
                              Key Decisions
                              • Namespace default import (import childProcess from "node:child_process") over
                                createRequire(import.meta.url) — the default import is the smaller diff and
                                
matches how the file's other imports are written.
                              Constraints & Invariants
                              • "type": "module" in packages/opencode/package.json must remain true (invariant).
                              • Do not reformat or touch lines 4–5 of the bin script.
                              Prior Art
                              • packages/opencode/src/index.ts — the launcher's import block, written in ESM style.
                              Source
                              • Root cause found in a live verification run (2026-09-01); node --check + --version
                                
confirmed the ESM parse failure before this brief was drafted.
