jackin-propose is a skill for Claude Code, Codex from jackin-project/jackin-dev. It costs 38 tokens per session (816 once invoked), scanned A, original, Apache-2.0.

A planning workflow that turns a feature idea or problem into a roadmap draft and an early pull request, without writing code.

In plain words
What is it for?
Use it to create a roadmap item, open its initial pull request, choose a branch, and optionally include research. Small fixes and implementation use different workflows.
Why use it?
It gives larger changes a tracked place and starts review before implementation begins.

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

jackin-propose 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 4d 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 — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.

jackin-propose

Turn a feature, improvement, or problem into a tracked roadmap item and an early PR. This skill never writes code — it collects everything for the roadmap item, opens the PR, and stops. Implementation is always a separate later step (/goal Implement <slug>.md).

jackin❯ rule files auto-load — BRANCHING.md, COMMITS.md, PULL_REQUESTS.md, docs/ rules, TODO.md (roadmap conventions). This skill sequences them.

When to use

  • Operator runs jackin-propose <idea or problem>.
  • Feature/idea worth a roadmap item.

When NOT to use

  • Small fix (typo, dep bump, one-liner) → jackin-create-pr.
  • Designing an existing item → jackin-brainstorm. Implementing one → /goal Implement <slug>.md.

Arguments

  • --branch <name> / --auto-branch — explicit / self-chosen branch name.
  • --no-pr — branch + roadmap draft only, no PR (rare; default opens a PR).
  • --research — run deep-research first and fold a short summary into the draft.

Process

  1. Branch. Never commit to main. Derive a feature/<slug> name (or fix/ / refactor/ / chore/ per change type) from the idea; suggest and confirm unless --auto-branch / --branch given.
  2. (optional) Research. On --research, run the built-in deep-research skill and summarize findings into the draft. For large research, prefer jackin-research.
  3. Scaffold the roadmap item. Run cargo xtask change new <slug> --group <group> — it creates docs/content/docs/roadmap/<slug>.mdx (**Status**: Open, ## Problem, ## Why It Matters, ## Design, ## Tasks, ## Related Files) and registers it in the chosen group's Fumadocs meta.json. Pick the --group from the existing roadmap groups. Then fill Problem / Why It Matters from the idea text, and run cargo xtask roadmap audit.
  4. Commit + push. docs: type, DCO -s, then git push.
  5. Open the PR. Unless --no-pr, build and open the PR with create-pr mechanics — Summary = the idea, What ships = "roadmap item draft for <slug>", Verify = docs render.
  6. Stop. Point the operator at the next step: jackin-brainstorm <slug> to fill ## Design. Do not implement.

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.
