What is appsec-threat-renderer?

An internal threat-modeling helper that renders the second stage of create-threat-model after the first stage produces validated intermediate files.

Rendering the outputs of Stage 1 of the create-threat-model process.

It separates rendering from the earlier threat-modeling work and is meant to be called only by that skill.

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.

Model	Per session	Once invoked
Fable 5	$0.00033	$0.20508
Opus 5	$0.00016	$0.10254
Sonnet 5	$0.00007	$0.04102
Haiku 4.5	$0.00003	$0.02051

Security

Grade A, and why

appsec-threat-renderer scanned grade A with 1 finding 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.

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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- Function-call literals: `models.sequelize.query()`, `eval()`, `fetch(url)`, `app.use(cors())`. Reword as the weakness class.

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.
