grafema: Skill for Claude Code

.claude/skills/dataflow-gauntlet-methodology/SKILL.md

dataflow-gauntlet-methodology is a skill for Claude Code from Disentinel/grafema. It costs 93 tokens per session (3,035 once invoked), scanned A, original, no licence file.

A repeatable testing method for checking whether a program-analysis tool follows data from its sources through all relevant steps in a new or existing programming language. It uses test fixtures and traces, then investigates and fixes missed paths.

In plain words
What is it for?
Use it when adding language support to Grafema, auditing an existing language, or diagnosing incomplete dataflow coverage.
Why use it?
It exposes gaps in dataflow analysis instead of relying on a few passing examples. The process continues until the intended backward paths are covered.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter.

This is Disentinel/grafema's own configuration. It tells Claude Code how to work on grafema 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 grafema 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

dataflow-gauntlet-methodology 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 8d 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.

The source is not reproduced here

A licence we could not identify

The repository carries a LICENSE file, but it is custom or dual enough that GitHub cannot name it and neither can this catalogue. Unknown terms are not permission, so the body is not copied here. Read the licence at the source and decide for yourself.

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.
