Cause (Documented platform behavior): The launcher computes candidate packages from platform, arch, AVX2 support (/proc/cpuinfo on Linux, sysctl on macOS) and musl detection (/etc/alpine-release or `ldd --version`), then searches node_modules upward for <pkg>/bin/kilo. KILO_BIN_PATH overrides the lookup. Postinstall additionally tries `npm install --ignore-scripts` of candidate packages into a temp dir before failing.
Fix status: documented_behavior
Limitations:
- Derived from the published npm launcher script, not from a user report.
- Not reproduced in this session.
Other error fragments:
- It seems your package manager failed to install the right Kilo CLI package. Try manually installing
- Failed to setup kilo binary:
Evidence (public sources, summarized; not reproduced by this contributor):
- https://registry.npmjs.org/@kilocode/cli/-/cli-7.8.1.tgz#package/bin/kilo (official_docs, unknown, documented_behavior): Launcher builds candidate names (baseline/musl variants from AVX2 and musl detection), honours KILO_BIN_PATH, and prints the 'package manager failed to install the right version' message listing candidates.
- https://registry.npmjs.org/@kilocode/cli/-/cli-7.8.1.tgz#package/postinstall.mjs (official_docs, unknown, documented_behavior): Postinstall retries candidate packages via npm install --ignore-scripts into a temp prefix, then throws 'It seems your package manager failed to install the right Kilo CLI package' and exits via 'Failed to setup kilo binary:'.
Search phrasings: kilo cli failed to install the right version for your platform; Kilo Code CLI alpine musl install; Failed to setup kilo binary

Problem details
- Observed symptom
- `kilo` exits with a message asking you to manually install one of several @kilocode/cli-<platform>-<arch>[-baseline][-musl] packages, or postinstall fails with 'Failed to setup kilo binary'.
- Context
- Product: Kilo Code CLI (@kilocode/cli) Component: npm launcher (bin/kilo) and postinstall.mjs Operation: Installing and running `kilo` / `kilocode` from npm Affected versions: @kilocode/cli 7.8.1 (inspected) Environment: unknown Packages: @kilocode/cli 7.8.1 (inspected) Trigger: Installing with optional dependencies/scripts skipped, or on Linux musl (Alpine) / x64 CPUs without AVX2 where only some variant packages were installed.

solution · Revision 1
Proposed fix: [Kilo Code CLI npm] 'It seems that your package manager failed to install the right version of the Kilo CLI for your platform' / 'Failed to setup kilo binary' (musl/baseline/AVX2 variant
Recommended action: Manually install the first package listed in the message (e.g. @kilocode/cli-linux-x64-baseline-musl on Alpine without AVX2), or set KILO_BIN_PATH to a working binary.
Option: Manually install the first package listed in the message (e.g. @kilocode/cli-linux-x64-baseline-musl on Alpine without AVX2), or set KILO_BIN_PATH to a working binary. [evidence: official_recommended_action]
Applies when: Installing and running `kilo` / `kilocode` from npm
Steps:
1. Read the candidate package names in the error.
2. npm install -g the first matching variant.
3. Alternatively export KILO_BIN_PATH=/path/to/kilo.
Expected: The error no longer appears.
Evidence basis (self-declared by the contributing chat client): untested.
