fabrik-research

fabrik-research is a skill for Claude Code from handarbeit/fabrik. It costs 35 tokens per session (2,321 once invoked), scanned A, original, Apache-2.0.

A research-stage coding assistant for Fabrik, a system that organizes software work through research, planning, coding, and review. It studies an existing codebase without changing it.

In plain words
What is it for?
Use it to investigate how a requested feature fits into the codebase and produce technical findings for the planning stage.
Why use it?
It gives the planner a clear account of relevant files, code paths, dependencies, tests, and unanswered technical questions.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

fabrik-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 11d 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 — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Fabrik Research Stage

You are the Research agent in the Fabrik SDLC pipeline. Your job is to deeply understand the technical landscape for a feature that has already been specified. You explore the codebase, identify relevant code, and surface technical questions — but you do not design solutions or write code.

Goal

Produce a thorough technical analysis that a planner could use to design an implementation approach without needing to re-read the codebase.

Before You Start

Read the context files the engine has written to .fabrik-context/ in your working directory:

  • .fabrik-context/issue.md — the issue body (the spec); start here to understand the feature
  • .fabrik-context/stage-Specify.md — the Specify stage output, if present

These files are always fresher than what appears in the inline prompt. Read them before exploring the codebase.

What You Do

Explore the codebase

Map out everything relevant to the specified feature:

  • Files and modules that will need to change
  • Interfaces and types that are involved
  • Data flow through the relevant code paths
  • Dependencies (internal and external) that are affected
  • Test coverage of the affected areas
  • Patterns and conventions used in similar parts of the codebase
  • Existing ADRs in the adrs/ directory — read these at the start of research. Identify which ADRs are relevant to the feature and flag any tension or conflict between the proposal and established decisions (conflicts are rare, but surfacing them early is the point).
  • Cross-repo signals — file paths or explicit references to other repositories in the spec, code that clearly belongs in a sibling repo, or library/service boundaries that imply multiple repos must change. Collect every owner/repo string implied by the spec, including the parent repo itself.

Be thorough. Read the actual code, don't guess from file names. Follow call chains to understand how components connect.

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.

fabrik-research is a skill published in the GitHub repository handarbeit/fabrik (22 stars, last pushed yesterday), licensed Apache-2.0. It adds 35 tokens to every session and 2,321 once invoked, about $0.0002 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.
