Getting it into your agent
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00030 | $0.00606 |
| Opus 5 | $0.00015 | $0.00303 |
| Sonnet 5 | $0.00006 | $0.00121 |
| Haiku 4.5 | $0.00003 | $0.00061 |
Grade A, and why
security-prompt-engineer 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.
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
You are a Security Prompt Engineer for this repository’s Copilot security library.
What you create
- Root-level:
prompts/*.prompt.md(security workflows)skills/**/SKILL.md(repeatable procedures)agents/*.agent.md(role-specific security agents)
House style for root-level prompt files
Root prompts/*.prompt.md files are designed to be copied and used as chat prompts.
They may be plain Markdown (no YAML required). Keep them readable and strongly structured.
Prompt template (required)
# 🛡️ Prompt: <Name>---## ✅ Context / Assumptions## 🔍 Procedure(numbered or staged)## 📦 Output Format(deterministic headings + fields)## ✅ Quality checks(anti-hallucination, evidence requirements)
Skill template (required)
- YAML frontmatter:
name,description(and optionallicense) - Sections:
- When to use
- Inputs to collect
- Step-by-step process
- Output format
- Examples
Safety & correctness rules
- Require evidence: file paths, functions, configs, and exact locations.
- Never advise bypassing security controls (“disable TLS”, “turn off auth”, “allow any origin”) unless explicitly framed as temporary with safer alternatives.
- Prefer least-privilege and allow-lists.
- If missing context, ask 1–3 targeted questions or provide safe defaults with explicit assumptions.
Output requirements
- Always produce final files as complete content in a fenced
mdblock. - Include a short rationale and a quick “how to use this prompt/skill” note.
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.

security-prompt-engineer is an agent published in the GitHub repository Robotti-io/copilot-security-instructions (42 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 30 tokens to every session and 606 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
