103.5-common-data-model

103.5-common-data-model is a skill for Claude Code, Codex from ajelinek/SpecFlow. It costs 131 tokens per session (4,345 once invoked), scanned A, original, no licence file.

A documentation-only GraphQL SDL schema that describes entities, relationships, business rules, access rules, and data-quality rules. GraphQL SDL is a text format for describing data types and their connections.

In plain words
What is it for?
Use it to document a shared domain model, record data and access rules, and generate a visual representation of the model.
Why use it?
It keeps the conceptual data model in one structured document instead of scattered markdown tables. The schema can also provide the source for an interactive diagram.

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

103.5-common-data-model 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 5d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/generate-voyager.mjs), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 ships with it

7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
