radin-plan

radin-plan is a skill for Claude Code, Codex from shortcuts/radin. It costs 53 tokens per session (2,504 once invoked), scanned A, original, MIT.

A planning tool that turns one backlog entry into a step-by-step implementation plan without changing code. A backlog entry is one stored piece of unfinished work.

In plain words
What is it for?
Use it to plan a feature, bug fix, follow-up, or other named backlog task before execution.
Why use it?
It makes the work clear before implementation begins and keeps planning separate from editing files. It handles one task at a time, not the entire backlog.

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

radin-plan 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 today.

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 — 235 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plan a Backlog Entry

You own the plan, not the code. The plan is a checklist an executor runs box by box, and a reviewer audits from the evidence each box names. It runs inline in whichever context invokes it. A caller that cannot reach the user says so in its prompt; the branches marked "non-interactive" are then the defaults, and anything only the user could settle is reported and stops the run.

Step 1: Resolve the task scope

RADIN_CLI backlog plan-target "<scope id/title/keyword>"

It prints id/title/task_file/plan_file lines, plus a facts<TAB><path> line when the entry carries one, plus one plan<TAB><path> line per plan the entry already has. Route on its exit code:

  • 0: resolved and unplanned. Use it.

  • 1: nothing matches. The task isn't in the backlog yet. Classify it into feat (new capability), fix (broken behavior), chore (maintenance: docs, tooling, cleanup) or refactor (structure only, no behavior change), create it without asking, then re-run plan-target on the printed id.

    RADIN_CLI backlog add <category> "<short title>" <<'EOF'
    <the task as the caller stated or clearly implied it, and why it matters
    if not already obvious>
    EOF
    
  • 2: several entries match; it prints them as candidate lines on stderr. Ask which one.

  • 3: already planned; the plan lines are the existing paths. Show them and ask whether to re-plan (overwrite) or stop. Stop unless confirmed.

Non-interactive, for exits 1-3: report what plan-target printed and stop. The scope came from an existing entry, so no match means backlog drift: the run adds no entry, picks no candidate, and overwrites no plan.

Step 2: Judge whether the scope should split

Split only when the entry bundles unrelated changes that can each be planned on its own. Interactive: state your read (split or not, and why) and confirm it; a confirmed split lists short titles and one-line descriptions with full coverage and no overlap. Non-interactive: no split.

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.
