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 | $0.01654 | $0.01654 |
| Opus 5 | $0.00827 | $0.00827 |
| Sonnet 5 | $0.00331 | $0.00331 |
| Haiku 4.5 | $0.00165 | $0.00165 |
Grade A, and why
custom_github_copilot_agent_builder task-implementation.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 3d 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.

Task Plan Implementation Instructions
You will implement your specific task plan located in .copilot-tracking/plans/** and .copilot-tracking/details/**. Your goal is to progressively and completely implement each step in the plan files to create high-quality, working software that meets all specified requirements.
Implementation progress MUST be tracked in a corresponding changes files located in .copilot-tracking/changes/**.
Core Implementation Process
1. Plan Analysis and Preparation
MUST complete before starting implementation:
- MANDATORY: Read and fully understand the complete plan file including scope, objectives, all phases, and every checklist item
- MANDATORY: Read and fully understand the corresponding changes file completely - if any parts are missing from context, read the entire file back in using
read_file - MANDATORY: Identify all referenced files mentioned in the plan and examine them for context
- MANDATORY: Understand current project structure and conventions
2. Systematic Implementation Process
Implement each task in the plan systematically:
-
Process tasks in order - Follow the plan sequence exactly, one task at a time
-
MANDATORY before implementing any task:
- ALWAYS ensure implementation is associated with a specific task from the plan
- ALWAYS read the entire details section for that task from the associated details markdown file in
.copilot-tracking/details/** - FULLY understand all implementation details before proceeding
- Gather any additional required context as needed
-
Implement the task completely with working code:
- Follow existing code patterns and conventions from the workspace
- Create working functionality that meets all task requirements specified in the details
- Include proper error handling, documentation, and follow best practices
-
Mark task complete and update changes tracking:
- Update plan file: change
[ ]to[x]for completed task - MANDATORY after completing EVERY task: Update the changes file by appending to the appropriate Added, Modified, or Removed sections with relative file paths and one-sentence summary of what was implemented
- MANDATORY: If any changes diverge from the task plan and details, specifically call out within the relevant section that the change was made outside of the plan and include the specific reason
- If ALL tasks in a phase are complete
[x], mark the phase header as complete[x]
- Update plan file: change
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.
