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.

Use it to plan a feature, bug fix, follow-up, or other named backlog task before execution.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00078	$0.01717
Opus 5	$0.00039	$0.00859
Sonnet 5	$0.00016	$0.00343
Haiku 4.5	$0.00008	$0.00172

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 8d 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 — 154 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plan a Backlog Entry

Turn one backlog entry into one or more implementation plans, without writing any code. Runs inline in whichever context invokes it. When the invoking context cannot reach the user (e.g. radin-execute's planning sub-agent), the caller says so; every question below then takes the non-destructive branch marked "non-interactive". Such a run also cannot be notified when a background task finishes, so /grilling and /research are interactive-only here — waiting on either hangs the caller. Each "non-interactive" branch below says what to do instead.

Step 1: Resolve project namespace

All backlog reads/writes go through the shared CLI at $HOME/.claude/.radin/lib/radin-backlog.sh — never hand-edit the backlog's index or task files, or compute their paths yourself. Get the paths (also creates the state/plans/reviews/tasks directories):

bash "$HOME/.claude/.radin/lib/radin-backlog.sh" env

Read REPO_ROOT, NAMESPACE_DIR, BACKLOG_INDEX, BACKLOG_TASKS_DIR from its output. Re-run this line in any later Bash call that uses them.

Step 2: Resolve the task scope

bash "$HOME/.claude/.radin/lib/radin-backlog.sh" find "<scope id/title/keyword>"

It prints one id<TAB>category<TAB>title<TAB>file line per match (exact id first, then exact title, else substring on title).

One match: use it.
Several: list them and ask which one. Non-interactive: report the candidates and stop.
None (interactive only): the task isn't in the backlog yet. Create it without asking — classify into feat/fix/chore/refactor (rubric in skills/radin-record/SKILL.md), then:
```
bash "$HOME/.claude/.radin/lib/radin-backlog.sh" add <category> "<short title>" <<'EOF'
<the task as the caller stated or clearly implied it, and why it matters
if not already obvious>
EOF
```
Report the new entry, then continue with it as the scoped entry. Non-interactive: the scope always came from an existing entry, so no match means backlog drift — report and stop instead of writing a duplicate.
Already planned: radin-backlog.sh meta "<id>" prints one plan<TAB><path> line per existing pointer. If any, show the path(s) and ask whether to re-plan (overwrite) or stop. Stop unless confirmed.

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.

radin-plan is a skill published in the GitHub repository shortcuts/radin (5 stars, last pushed yesterday), licensed MIT. It adds 78 tokens to every session and 1,717 once invoked, about $0.0004 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.
