one-by-one

one-by-one is a skill for Claude Code from jackfranklin/dotfiles. It costs 63 tokens per session (1,034 once invoked), scanned A, original, MIT.

A guided way to work through a list of code-review findings, design questions, or other decisions one item at a time. Each item includes its context, why it matters, and concrete options for addressing it.

In plain words
What is it for?
Use it to discuss review findings, open decisions, or design questions interactively in sequence.
Why use it?
Long lists of issues are easier to understand and resolve when each one gets focused attention. It keeps the discussion from jumping ahead before the current item is settled.

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

one-by-one 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 6d 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.

How it starts

The opening of the file, as written. The whole thing — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.

One-by-One

Guide the user through a list of findings interactively, one at a time. Each finding gets its own focused conversation: context, background, the problem it points to, and options for what to do about it. Do not rush ahead or present the next item until the user is done with the current one.

Your role

  • Orient first. At the start, briefly acknowledge how many items you're working through and start with item 1. Don't ask the user if they want to begin — they already invoked the skill.
  • One finding at a time. Present each finding fully, then end with the closing prompt and wait for the user to respond before moving on.
  • Give real context. Don't just restate the finding. Explain why it matters: what could go wrong, what pattern it violates, what it makes harder to maintain or change. Reference the relevant code if you have it.
  • Offer concrete paths forward. Give one option if there is genuinely only one reasonable path — that's a valid answer, not a shortcut. Don't reduce to one option just because you have a preference; if the options represent meaningfully different approaches or trade-offs, present them separately. Give two or three when trade-offs genuinely depend on context or constraints — but only count options that represent meaningfully different paths; don't pad. Beyond three genuinely distinct options, you're doing the user's sorting work for them — collapse them and strengthen your recommendation instead. Be specific — name the function, change, or pattern, not vague advice like "refactor this". If you have questions for the user (e.g. about intent or constraints), ask them before presenting options.
  • Handle mid-finding dialogue. If you asked a scoping question and the user answers, or if the user asks a follow-up rather than making a decision, respond and continue the conversation within the same finding. Only advance to the next finding when the user has made a clear decision (fix, defer, or dismiss). Re-present the options in the format block if the scoping answer changes what you'd recommend.
  • Honour the user's decision. The user may want to fix it, defer it, dismiss it, or discuss it further. Accept any of these and move on.
  • Track position. Always make clear which finding you're on (e.g. "Finding 2 of 7") so the user knows where they are.

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.

one-by-one is a skill published in the GitHub repository jackfranklin/dotfiles (254 stars, last pushed 4d ago), licensed MIT. It adds 63 tokens to every session and 1,034 once invoked, about $0.0003 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 2026-08-30.
