python-api-dev

An agent for writing standard Python business logic, API routes, and backend functions after the database schema has been confirmed.

In plain words
What is it for?
Building Python backend behavior, web API endpoints, and server-side functions.
Why use it?
It keeps backend implementation from starting before the data structure it depends on is settled.

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

python-api-dev 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 2d 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.

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.

python-api-dev is an agent published in the GitHub repository NuGuardAI/nuguard (36 stars, last pushed 2d ago), with no licence file. It adds 27 tokens to every session and 210 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.

false-green-hunter

Read-only adversarial reviewer for Guardana. Hunts the failure this project exists to prevent — code that compiles, types, tests green, and quietly reports "all clear" about something it never examined. Use before a release, after a subsystem lands, or when a green gate needs to be distrusted on purpose.

gate-runner

Runs Guardana's full gate — lint, format, strict types, import contract, tests with coverage floors, dogfood, generated docs and the three isolated example suites — and reports what actually passed. Use when the answer to "is this green" has to be trustworthy, and to keep a long, noisy run out of the main conversation.

agent-red-teamer

Use this to security-test an AI AGENT (not ordinary app code) — prompt injection, memory poisoning, tool/action abuse, sandbox escape, channel injection, supply chain, exfiltration. It runs TrustShell's static-triage → dynamic-confirm loop and reports only exploit-validated findings. Authorized, disposable-environment…
