praxia-agents: Skill for Claude Code

.claude/skills/praxia-backend/SKILL.md

praxia-backend is a skill for Claude Code from atmosware/praxia-agents. It costs 63 tokens per session (150 once invoked), scanned A, original, MIT.

A backend follow-up skill that turns findings from cognia-backend into proposed code and configuration fixes. It can apply those fixes after a person approves them.

In plain words
What is it for?
Use it after a cognia-backend report to improve endpoints, services, input checks, authentication, database queries, API contracts, error handling, or configuration.
Why use it?
It provides a concrete next step after a backend review instead of leaving the findings as a report. The changes target common problems such as validation, authentication, database queries, and error handling.

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

praxia-backend 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 10d 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 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.
