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.

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 | $0.01272 | $0.01272 |
| Opus 5 | $0.00636 | $0.00636 |
| Sonnet 5 | $0.00254 | $0.00254 |
| Haiku 4.5 | $0.00127 | $0.00127 |
Grade A, and why
Copilot-Skills skill-template.instructions.md 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.
How it starts
The opening of the file, as written. The whole thing — 163 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Template - Automatic Context Instructions
Related Prompt: /skill-template
Related Skill: .github/copilot-skills/skill-template/
Triggers: create skill, new skill, skill template, skill architecture, skill structure, skill patterns
Context: Skill Creation and Architecture
When working with skill-related files or when user queries contain skill creation keywords, this context is automatically activated.
Core Principles
Three-Part System
- Prompt File - Defines WHEN and HOW to use skill (
.github/prompts/) - Instructions File - Auto-loaded context rules (
.github/instructions/) - Skill Directory - Bundled scripts and detail files (
.github/copilot-skills/)
Five Constitutional Principles
- Progressive Disclosure - Load core first, details on demand
- File-Based Organization - Skills are discoverable files
- Dynamic Discovery - Index enables AI to find skills
- Deterministic Execution - Scripts produce consistent output
- Composability - Skills reference each other clearly
Default Behaviors
When user mentions "create skill" or "new skill"
- Suggest
/skill-templateskill prompt - Guide through template copying process
- Validate structure follows constitutional principles
- Help register in keyword routing map
When user mentions "skill architecture" or "skill patterns"
- Suggest
/skill-templateskill prompt - Load
.github/copilot-skills/skill-template/README.mdfor overview - Reference existing skills as examples (git-ops, pdf-handling)
When user asks about "bundled scripts" or "script templates"
- Suggest
/skill-templateskill prompt - Show example scripts in
.github/copilot-skills/skill-template/scripts/ - Reference script templates in
.github/copilot-skills/templates/
Quality Guidelines
✅ Do
- Use templates from
.github/copilot-skills/templates/ - Follow three-part system (prompt + instructions + directory)
- Validate against five constitutional principles
- Register new skills in keyword routing map (
.github/copilot-instructions.md) - Use progressive disclosure (load on-demand, not all at once)
- Make scripts deterministic (terminal output only)
- Document trigger keywords in instructions file
- Cross-reference related skills
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.

Copilot-Skills skill-template.instructions.md is an instructions file published in the GitHub repository TheSethRose/Copilot-Skills (3 stars, last pushed 8mo ago), licensed MIT. It adds 1,272 tokens to every session, about $0.0064 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 2026-08-31.
