namespace-diagnostic-wording

namespace-diagnostic-wording is a cursor rule for Codex from prisma/orm. It costs 101 tokens per session, scanned A, original, Apache-2.0.

Guidelines for messages shown when a namespaced attribute uses an extension namespace that the project's configuration does not recognise.

In plain words
What is it for?
Use it when writing diagnostics for namespaced schema attributes, including the namespace name and instructions to add its extension pack.
Why use it?
Clear wording helps users understand that the namespace is unavailable and what configuration is missing.

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

namespace-diagnostic-wording 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 3d 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 it actually says

Namespace diagnostic wording

When a PSL namespaced attribute is used but the namespace is unavailable in config, avoid phrasing like "namespace not composed".

Use clear user-facing wording such as:

  • "unrecognized namespace"
  • "namespace is not available"

Preferred guidance in messages:

  • Name the namespace explicitly.
  • Tell the user to add the corresponding extension pack to extensions in prisma.config.ts.

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.
