FreeFM

Set up and operate the FreeFM Rust app for NetEase Private FM, including its TUI, QR login, read-only preview, append-only sync, diagnostics, and zero-LLM scheduling.

Operate FreeFM as a one-shot native CLI. Use an Agent only for interactive setup or troubleshooting; scheduled synchronization must execute the binary directly without a model turn.

Guardrails

• Work only with the user's own NetEase Cloud Music account.
• Never ask the user to paste MUSIC_U, cookies, session files, or QR keys.
• Never print, inspect, summarize, upload, or commit credentials or playback URLs.
• Never unlock restricted content, replace audio URLs, download audio, or automatically substitute a searched recording.
• Run preview before the first sync. Only sync may write remotely.
• Do not schedule until one manual preview and one manual sync have succeeded.

Locate or install the CLI

Prefer an existing freefm on PATH, then $HOME/.local/bin/freefm. If it is missing, tell the user to install the public alpha from source:

sh

cargo install --git https://github.com/Yuxin-Qiao/FreeFM --locked --root "$HOME/.local"

Do not run an installer without explicit user approval. FreeFM supports macOS and Linux only.

Interactive workflow

Run authentication in a terminal visible to the user so they can scan the QR code with the official NetEase Cloud Music client:

sh

freefm tui
freefm auth
freefm status --json
freefm preview --json
freefm sync
freefm sync --quiet

Use freefm tui for guided interactive setup. It is only a front end for the commands below. Never use the TUI in a scheduler.

Confirm authenticated=true and account_vip_type=0 before sync. Treat login_required, ordinary_account_required, api_incompatible, ambiguous playlist ownership, unknown availability, and any non-zero exit as a manual review condition. Never infer success from an empty failed run.

OpenClaw deterministic automation

Resolve the absolute binary path first. Create an operator-admin command job with exact argv, no delivery, and no Agent/model payload:

sh

openclaw automations create "0 * * * *" \
  --name "FreeFM hourly sync" \
  --command-argv '["/absolute/path/to/freefm","sync","--quiet"]' \
  --no-deliver \
  --timeout-seconds 120

Use openclaw automations list to obtain the job ID, then verify one run with openclaw automations run <job-id> --wait. Command payloads execute inside the Gateway scheduler without starting a model-backed turn. Do not replace --command-argv with an agent message.

Hermes no-agent automation

Install the bundled fixed-command helper, then create a script-only cron:

sh

install -d -m 700 "$HOME/.hermes/scripts"
install -m 755 "{baseDir}/scripts/freefm-sync.sh" "$HOME/.hermes/scripts/freefm-sync.sh"

Hermes 0.17 may install only SKILL.md from a community GitHub/skills.sh source. If {baseDir}/scripts/freefm-sync.sh is absent, ask for approval and fetch the helper from the immutable source commit, then verify it before use:

sh

helper=$(mktemp)
curl -fsSL \
  https://raw.githubusercontent.com/Yuxin-Qiao/FreeFM/c7bcf10dce142fd85c84f82173a307e91ea99adc/skills/freefm/scripts/freefm-sync.sh \
  -o "$helper"
test "$(shasum -a 256 "$helper" | awk '{print $1}')" = \
  "b9dd3bd85e32c8ce57ba11ef474149839ad898090495daf7336d396d37830fd1"
install -d -m 700 "$HOME/.hermes/scripts"
install -m 755 "$helper" "$HOME/.hermes/scripts/freefm-sync.sh"
rm -f "$helper"

Then create the job:

sh

hermes cron create "0 * * * *" \
  --name freefm-hourly \
  --script freefm-sync.sh \
  --no-agent

Use hermes cron list to obtain the job ID and hermes cron run <job-id> for one manual verification. --no-agent makes the script the job; empty stdout on success is silent and consumes no LLM tokens.

Verification

• freefm status --json reports an authenticated ordinary account.
• freefm preview --json reports decisions without creating or appending.
• A repeated freefm sync --quiet exits zero with empty stdout and stderr.
• The scheduler history reports success and no Agent/model invocation.
• FreeFM is absent from the process list between scheduled runs.
