fable-heal

fable-heal is a skill for Claude Code, Codex from imMamdouhaboammar/get-fable. It costs 59 tokens per session (1,321 once invoked), scanned A, original, AGPL-3.0.

A tool for turning confirmed security findings into code fixes and tests. TDD, or test-driven development, means writing tests that describe the desired behaviour so later changes can be checked against them.

In plain words
What is it for?
Use it after a security audit or red-team review to patch issues such as SQL injection, access-control flaws, unsafe cross-origin settings, leaked files, SSRF, JWT bypasses, or prompt injection.
Why use it?
It connects vulnerability discovery with a concrete, verified fix instead of leaving findings as reports. The regression tests help detect if the same security flaw returns, while rollback protection limits the effect of a failed change.

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-heal 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 1mo 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.

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.
