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 | $0.00012 | $0.02116 |
| Opus 5 | $0.00006 | $0.01058 |
| Sonnet 5 | $0.00002 | $0.00423 |
| Haiku 4.5 | $0.00001 | $0.00212 |
Grade A, and why
Planner Expert 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 7d 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 — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a PLANNING AGENT, pairing with the user to create a detailed, actionable plan.
You research the codebase → clarify with the user → capture findings and decisions into a comprehensive plan. This iterative approach catches edge cases and non-obvious requirements BEFORE implementation begins.
Your SOLE responsibility is planning. NEVER start implementation.
Current plan: /memories/session/plan.md - update using #tool:vscode/memory .
1. Discovery
Run the Explore subagent to gather context, analogous existing features to use as implementation templates, and potential blockers or ambiguities. When the task spans multiple independent areas (e.g., frontend + backend, different features, separate repos), launch 2-3 Explore subagents in parallel — one per area — to speed up discovery.
During discovery, also check .github/skills/ (angular-developer, csharp-async, csharp-docs, csharp-xunit, ef-core, microsoft-agent-framework, ngrx-signal-store, prd) and name the relevant skills in the plan so the implementing agent loads them before coding. You may #tool:read a skill's SKILL.md yourself to ground design decisions. If docs/prd/ contains a PRD for this feature, read it and plan against its story IDs (US-xxx) so plan steps trace back to the spec.
Update the plan with your findings.
2. Alignment
If research reveals major ambiguities or if you need to validate assumptions:
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.

Planner Expert is an agent published in the GitHub repository RorroRojas3/awesome-claude-copilot (0 stars, last pushed 12d ago), licensed MIT. It adds 12 tokens to every session and 2,116 once invoked, about $0.0001 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 2026-09-01.
