jackin-research

jackin-research is a skill for Claude Code, Codex from jackin-project/jackin-dev. It costs 40 tokens per session (811 once invoked), scanned A, original, Apache-2.0.

A research workflow that creates a multi-page dossier on an open question or roadmap topic using evidence from the web and codebase. A dossier is a structured set of research pages.

In plain words
What is it for?
Use it for in-depth roadmap research, either from the web, the codebase, or both, with options to create only a research brief or keep findings in the roadmap.
Why use it?
It organizes substantial investigation into a reusable document while keeping evidence separate from product design decisions.

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-research 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 5d 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 — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.

jackin-research

Produce a standalone research dossier — a multi-page deliverable published on the jackin❯ docs site — for an open question or roadmap topic. Brief-driven: author the brief, then execute it. Gathers and synthesizes evidence (web + codebase); does not make product design decisions.

Reference implementation: docs/content/docs/research/token-optimization-research/ in the jackin❯ repo.

When to use

  • Operator runs jackin-research <slug> for a substantial investigation.

When NOT to use

  • Design decisions on a roadmap item → jackin-brainstorm.
  • Quick lookup → deep-research or Explore directly, no dossier.

Arguments

  • --brief-only — author prompt.mdx (the brief) and stop; execute later via /goal Follow <brief>.
  • --in-roadmap — store findings inline in the roadmap item instead of a separate dossier (small research only).
  • --web-only / --codebase-only — restrict gathering to one pass.

Output layout (default: separate folder)

docs/content/docs/research/<slug>/
├── meta.json     # { title, defaultOpen:false, pages:[...] } — sidebar order
├── index.mdx     # dossier landing: headline numbers, how-to-read, tier list
├── prompt.mdx    # the brief that was run (the spec; carries the /goal run line)
├── NN-*.mdx      # numbered chapters (00 summary, 01.. foundations, 10-20 areas, 30+ synthesis)
└── tools/        # optional scripts + own meta.json + index.mdx

Also add <slug> to the parent docs/content/docs/research/meta.json pages. Big research → own folder (default); small → --in-roadmap.

Process

  1. Scope / brief. From the topic (or roadmap item), draft or load prompt.mdx: mission, chapter list, evidence rules. With --brief-only, stop here.
  2. Gather. Web via the built-in deep-research; codebase via Explore/grep. Every external claim carries a source URL; every local number carries its method.
  3. Write. index.mdx (headline numbers + how-to-read + tier list) and the numbered chapters in a fixed per-technique record schema; bundle any reproduction scripts under tools/.
  4. Wire the sidebar. Create/update the dossier meta.json and the parent research/meta.json.
  5. Docs gate + commit. Run the bun docs gate (build, check:repo-links, tsc --noEmit, test) from docs/. Commit docs(research):; push.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
