Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

impact-statusline scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Fallow Impact statusline

Arguments: $ARGUMENTS

Manage Fallow's branded, compact Impact segment for Claude Code. Never enable Impact on the user's behalf.

Parse the request

  • Action: status, setup, or remove. Default to status.
  • Scope: user or project. Default to user.
  • Mode for setup: replace or compose.
  • project means the private, gitignored .claude/settings.local.json in ${CLAUDE_PROJECT_DIR}. Never edit the shared .claude/settings.json.

Command forms:

node "${CLAUDE_PLUGIN_ROOT}/bin/fallow-impact-statusline.mjs" inspect --scope user --root "${CLAUDE_PROJECT_DIR}"
node "${CLAUDE_PLUGIN_ROOT}/bin/fallow-impact-statusline.mjs" install --scope user --root "${CLAUDE_PROJECT_DIR}" --mode compose --confirm
node "${CLAUDE_PLUGIN_ROOT}/bin/fallow-impact-statusline.mjs" remove --scope user --root "${CLAUDE_PROJECT_DIR}" --confirm

Status

Run inspect and report:

  • the exact preview;
  • whether a statusline already exists;
  • whether Fallow already manages it;
  • the settings scope and path.

Do not modify files.

Setup

  1. Run inspect first and show the exact preview.
  2. If no statusline exists, use replace.
  3. If a command-based statusline exists and no mode was supplied, ask whether to compose with it or replace it. Recommend compose.
  4. If a non-command statusline exists and no mode was supplied, explain that it cannot be composed and ask whether to replace it.
  5. Only after that decision, run install with --mode <mode> --confirm.
  6. Report the settings path and tell the user the statusline appears on the next Claude interaction.

If the preview says fallow impact off, tell the user they may run fallow impact enable themselves. Do not run it.

Remove

Run remove --confirm and report the result. When the helper refuses because the statusline changed after Fallow setup, tell the user and do not overwrite their configuration by hand.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
