get-fable: Instructions file for Claude Code

AGENTS.md

get-fable AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from imMamdouhaboammar/get-fable. It costs 733 tokens per session, scanned A, original, MIT.

A project-specific instruction file for get-fable, a repository workflow for inspectable AI-assisted software development.

In plain words
What is it for?
Use it to route work through the project’s lifecycle documents and tools, investigate unknowns, plan testable changes, delegate independent tasks, and record progress.
Why use it?
It requires capability claims to be backed by current evidence and separates discovery, implementation, testing, review, security, and release decisions.

Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: Claude Code plugin machinery, but also the file is AGENTS.md. Also seen: mentions Codex; $skill-name invocation.

This is imMamdouhaboammar/get-fable's own configuration. It tells Claude Code, Codex and OpenCode how to work on get-fable itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything get-fable configures →

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

get-fable AGENTS.md 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 9d 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.

get-fable repository instructions

Purpose

This repository provides an inspectable coding lifecycle for AI-assisted software work. Keep every capability claim tied to implemented behavior and current evidence.

Working contract

  • Use root skills/ and skills/get-fable/registry.json as the canonical workflow source.
  • Route by the missing evidence or decision rather than loading every skill.
  • Resolve repository unknowns with fable-discover and current external facts with fable-research before they influence architecture.
  • Use bounded cards for broad work and fable-tdd for meaningfully testable behavior changes.
  • Delegate only independent work with explicit ownership and acceptance.
  • Treat verification, code review, security review, release readiness, handoff, and agent-control evaluation as separate claims.
  • Keep durable task state in docs/SPEC.md, .fable/LEDGER.md, .fable/PROGRESS.md, and .fable/state.json when the project is initialized.
  • Record workspace mutation generations and require fresh completion-capable evidence after the final mutation.
  • On repeated failure, diagnose harness and execution-path problems before another product edit.
  • Preserve existing user-owned configuration. Installation and initialization must remain explicit and idempotent.
  • Do not add credentials, private MCP configuration, raw prompts/transcripts to evidence state, local absolute paths, or unsupported vendor/model claims.
  • Do not describe reusable Markdown assets as automatic integration unless installer/runtime support exists in source.

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.
