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 5.1 | $0.17981 | $0.17981 |
| Opus 5.5 | $0.07192 | $0.07192 |
| Sonnet 5.5 | $0.03596 | $0.03596 |
| Haiku 4.5 | $0.01798 | $0.01798 |
Grade A, and why
custom_github_copilot_agent_builder AGENTS.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 1mo 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 — 2,730 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Project Overview
What This Project Is
This is NOT a static template copier. This is an intelligent AgentOps framework generator that analyzes target repositories and generates customized Copilot/AgentOps frameworks tailored to each repository's specific needs.
The custom_github_copilot_agent_builder is designed to be a repository-specific Copilot/AgentOps framework generator. Instead of blindly copying static templates, it:
- Analyzes target repositories deterministically
- Decides what the repository needs using agentic planning
- Generates appropriate files (Markdown/YAML) with managed-block markers
- Opens pull requests with the generated framework
- Maintains frameworks through idempotent regeneration
Core Purpose
Generate and maintain high-quality, repo-specific Copilot/AgentOps frameworks that include:
- Repo-wide instructions:
.github/copilot-instructions.md - Path-specific instructions:
.github/instructions/*.instructions.md - Custom agents:
.github/agents/*.agent.md(planner, implementer, reviewer, specialists) - Prompt files:
.github/prompts/*.prompt.md(Copilot chat skills) - GitHub Models prompts:
*.prompt.yml(eval-ready workflows) - Governance files:
repo-profile.md,mcp.md,decision-log.md(at repository root) - Context and memory:
*.context.md,*.memory.md - Spec templates:
docs/specs/*.md
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.

custom_github_copilot_agent_builder AGENTS.md is an instructions file published in the GitHub repository dhar174/custom_github_copilot_agent_builder (7 stars, last pushed 8mo ago), licensed MIT. It adds 17,981 tokens to every session, about $0.0719 per session on Opus 5.5. 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.
