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 | $0.00039 | $0.00321 |
| Opus 5.5 | $0.00016 | $0.00128 |
| Sonnet 5.5 | $0.00008 | $0.00064 |
| Haiku 4.5 | $0.00004 | $0.00032 |
Grade A, and why
plan-sprint 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 4d 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.
What it actually says
Sprint Planning
Plan the following feature into stories:
Instructions
Use the Agent tool with subagent_type: "planner" to:
- Explore the aiagent codebase to understand the current state of related functionality
- Break the feature into ordered, implementable user stories
- Identify dependencies between stories
- Estimate complexity (S/M/L) based on number of layers touched
Expected Output
The planner will produce a sprint plan:
## Sprint Plan: [Feature Name]
### Stories (ordered by dependency)
**Story 1: [Title]** — Size: S/M/L
- Goal: [one sentence]
- Acceptance Criteria: [2–5 bullet points]
- Depends on: [none or Story N]
- Layers touched: [entities / interfaces / services / repositories / TUI / Web UI]
**Story 2: ...**
Important
- Stories should be independently shippable where possible
- Each story should be small enough to implement and test in one session
- Dependencies must be explicit — a story that requires another story's entities or interfaces must list it
- Use
/refine-storyon each story before starting implementation
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.

plan-sprint is a skill published in the GitHub repository drujensen/aiagent (5 stars, last pushed 2mo ago), licensed MIT. It adds 39 tokens to every session and 321 once invoked, about $0.0002 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 2026-10-03.
