tune

tune is a skill for Claude Code, Codex from thgMatajs/squirrel-mode. It costs 26 tokens per session (866 once invoked), scanned A, original, MIT.

A command for changing one setting in an existing squirrel-mode profile without repeating its seven-question setup interview. The profile stores preferences such as language, tone, list size, and code style.

In plain words
What is it for?
Use it to inspect the current profile and change one selected formatting preference.
Why use it?
It makes a small preference change quicker and shows missing or invalid settings instead of silently guessing them. It asks the user to run `/squirrel:init` first if no profile exists.

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

tune 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.

squirrel-mode tuning

/squirrel:tune edits one field of the existing profile at ~/.squirrel/profile.md. It never re-runs the seven-question interview.

Procedure

  1. Read ~/.squirrel/profile.md. If it does not exist, say so in one line, tell the user to run /squirrel:init first, and stop there.
  2. Show the current value of all 11 fields as one compact block: language, answer_position, step_style, max_list_items, code_style, explanation_budget, options_per_answer, confirm_topic_switch, progress_recap, extras_section, tone. If the file exists but a given field's line is missing entirely, or is malformed - not in the exact field: value shape, or carrying a value outside that field's allowed values - show that field as unset (for example, tone: (unset)) rather than guessing a value, and treat it as the rules/base-rules.md default for that field until the user sets it explicitly through this command. Do not write that default into the file on your own initiative; showing it is not setting it.
  3. Ask exactly one question: which field to change, and to what. Offer field-name options as multiple-choice when 4 or fewer are the likely candidates from context; otherwise ask the user to name the field directly.
  4. Any of the 11 fields can be changed this way, one at a time, including the four that /squirrel:init question 2 set together as a bundle (step_style, explanation_budget, extras_section, tone). Each of the four is independently editable here even though the interview only ever set it alongside the other three.
  5. Validate the new value against the allowed values for that field before writing anything:
    • language: pt-BR, en, es, or auto.
    • answer_position: first or after-one-line-context.
    • step_style: numbered or checklist.
    • max_list_items: an integer from 3 to 7.
    • code_style: code-first or step-by-step.
    • explanation_budget: a positive integer.
    • options_per_answer: a positive integer.
    • confirm_topic_switch: yes or no.
    • progress_recap: yes or no.
    • extras_section: yes or no.
    • tone: neutral, warm, or terse. If the requested value is not on this list, say so in one line and ask again, for that same field only.
  6. Rewrite ~/.squirrel/profile.md with the new value in place and every other field unchanged, keeping the same field: value shape the file already has. Write is non-atomic (ADR-0003 Amendment P3); other open Claude Code sessions pick up the change on their next prompt via profile mtime reinjection - do not invent an installer-style write script.
  7. Confirm the change in one line, naming the field and its new value. Do not re-show the whole profile unless asked.
  8. If the user asks to change more than one field, handle them one at a time: confirm the first change, then repeat the one-question step for the next field. Never ask about two fields in the same message.

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.

tune is a skill published in the GitHub repository thgMatajs/squirrel-mode (2 stars, last pushed 15d ago), licensed MIT. It adds 26 tokens to every session and 866 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
