Error message

bun pm pack failed

What it means

When building the coding-agent from source for the 'source' install mode, the runner shells out to `bun pm pack` in the coding-agent directory. If the command exits non-zero, the runner dumps its captured stdout/stderr to stderr and throws this generic wrapper error. The real cause is in the piped output, not the message itself.

Solutions

1. Re-run with the stderr shown just before the throw — it contains bun's actual error message; fix that root cause.
2. Ensure bun is installed and on PATH: `which bun && bun --version`.
3. Run `bun install` in packages/coding-agent (and repo root) so pack has a consistent lockfile/workspace.
4. Verify packages/coding-agent/package.json is valid and the package name/version fields are sane.
5. Check disk space and write permissions on the bench directory.

Example fix

// before (shell, reproducing what the runner runs)
cd packages/coding-agent && bun pm pack   # fails: no node_modules
// after
bun install && cd packages/coding-agent && bun pm pack

import { $ } from "bun";
const bunPath = await $`which bun`.quiet().nothrow();
if (bunPath.exitCode !== 0) throw new Error("bun is required to pack the coding-agent from source");

try {
  await buildFromSource();
} catch (e) {
  if (e instanceof Error && e.message === "bun pm pack failed") {
    // root cause was already written to stderr by the runner
    console.error("bun pm pack failed — check the stderr above (bun missing? deps not installed?).");
  } else throw e;
}

When it happens

Trigger: bun not installed or wrong version; the coding-agent package has a broken package.json; bun pm pack fails due to a registry/network issue resolving pack metadata; filesystem permission problems writing the tarball into benchDir.

Common situations: Fresh machine without bun in PATH for the harness process; dirty worktree with missing workspace deps (needs `bun install` first); disk full; running in CI where the monorepo was partially checked out.
