fable-artifact

fable-artifact is a skill for Claude Code, Codex from imMamdouhaboammar/get-fable. It costs 96 tokens per session (1,737 once invoked), scanned A, original, MIT.

A workflow for creating structured technical documents and visual artifacts, such as proposals, architecture diagrams, Mermaid charts, and interactive components.

In plain words
What is it for?
It is for RFCs, architecture documents, technical reports, runbooks, decision records, diagrams, and standalone documentation.
Why use it?
It checks that the finished artifact communicates accurate claims, shows assumptions, and works in the format people will actually read.

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

fable-artifact 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 7d 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 — 196 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Fable Artifact

Turn requirements and evidence into a standalone artifact whose content, structure, diagrams, links, and rendered output can all be checked independently.

Mission

An artifact is not successful because the Markdown parses or the diagram looks polished. It must communicate the right claims to the right audience, preserve source truth, make assumptions visible, and render in the medium the user will actually consume.

Activate When

  • producing RFCs, architecture proposals, technical reports, runbooks, decision records, diagrams, or rich standalone documentation;
  • packaging analysis/results into a durable document;
  • creating a diagram or interactive explanatory artifact from established requirements/evidence.

Do Not Activate When

  • a one-paragraph answer is sufficient;
  • application logic itself needs modification (fable-execute);
  • the main work is numerical chart selection (fable-dataviz);
  • facts required by the artifact have not been researched/discovered yet.

Artifact Classification

Artifact Primary contract
RFC/proposal decision, alternatives, trade-offs, acceptance/rollout
Architecture doc boundaries, data/control flow, invariants, deployment
Runbook trigger, prerequisites, executable steps, rollback/escalation
Incident/report timeline/evidence/impact without invented causality
Decision record context, decision, alternatives, consequences
Diagram semantic topology/sequence/state, not decorative boxes
Interactive explainer accessible interaction + deterministic content/source

Protocol

Stage 1 — Define audience and job

State who will use the artifact and what decision/action it must support. One artifact can contain multiple sections, but it should have one primary communication job.

Stage 2 — Build a claim/source map

Before writing polished prose, identify:

  • measured/source-backed facts;
  • design decisions;
  • assumptions/inferences;
  • unresolved items;
  • data/visual sources;
  • claims that need citations/links.

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.
