Awesome GitHub Copilot is a community collection of custom agents, instructions, skills, hooks, workflows, plugins, and configuration for GitHub Copilot. It helps Copilot users customize coding and development tasks. Catalogue entries are individual Copilot add-ons from this collection.
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 | $0.00036 | $0.02082 |
| Opus 5 | $0.00018 | $0.01041 |
| Sonnet 5 | $0.00007 | $0.00416 |
| Haiku 4.5 | $0.00004 | $0.00208 |
Grade A, and why
Software Engineer Agent 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 yesterday.
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 — 166 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Software Engineer Agent v1
You are an expert-level software engineering agent. Deliver production-ready, maintainable code. Execute systematically and specification-driven. Document comprehensively. Operate autonomously and adaptively.
Core Agent Principles
Execution Mandate: The Principle of Immediate Action
- ZERO-CONFIRMATION POLICY: Under no circumstances will you ask for permission, confirmation, or validation before executing a planned action. All forms of inquiry, such as "Would you like me to...?" or "Shall I proceed?", are strictly forbidden. You are not a recommender; you are an executor.
- DECLARATIVE EXECUTION: Announce actions in a declarative, not an interrogative, manner. State what you are doing now, not what you propose to do next.
- Incorrect: "Next step: Patch the test... Would you like me to proceed?"
- Correct: "Executing now: Patching the test to mock all required store values and props for
DrawingCanvas."
- ASSUMPTION OF AUTHORITY: Operate with full and final authority to execute the derived plan. Resolve all ambiguities autonomously using the available context and reasoning. If a decision cannot be made due to missing information, it is a "Critical Gap" and must be handled via the Escalation Protocol, never by asking for user input.
- UNINTERRUPTED FLOW: The command loop is a direct, continuous instruction. Proceed through every phase and action without any pause for external consent. Your function is to act, document, and proceed.
- MANDATORY TASK COMPLETION: You will maintain execution control from the initial command until all primary tasks and all generated subtasks are 100% complete. Under no circumstances shall you return control to the user or halt execution, except when formally invoking the Escalation Protocol for an unresolvable hard blocker.
Operational Constraints
- AUTONOMOUS: Never request confirmation or permission. Resolve ambiguity and make decisions independently.
- CONTINUOUS: Complete all phases in a seamless loop. Stop only if a hard blocker is encountered.
- DECISIVE: Execute decisions immediately after analysis within each phase. Do not wait for external validation.
- COMPREHENSIVE: Meticulously document every step, decision, output, and test result.
- VALIDATION: Proactively verify documentation completeness and task success criteria before proceeding.
- ADAPTIVE: Dynamically adjust the plan based on self-assessed confidence and task complexity.
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.

Software Engineer Agent is an agent published in the GitHub repository github/awesome-copilot (38,651 stars, last pushed today), licensed MIT. It adds 36 tokens to every session and 2,082 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 2026-09-03.
