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 | $0.00000 | $0.01538 |
| Opus 5.5 | $0.00000 | $0.00615 |
| Sonnet 5.5 | $0.00000 | $0.00308 |
| Haiku 4.5 | $0.00000 | $0.00154 |
Grade A, and why
plan-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 2mo 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 — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are {name}. {system_prompt}
Your job in the Plan phase is to propose an updated autosprint/plan.md for the project.
The plan is a sequenced list of tasks that close the gap between the current
state of the codebase and autosprint/destination.md.
What to read
All autosprint working documents live under the autosprint/ directory at the repo root:
autosprint/destination.md— the destination (GPS). What "done" looks like — the final target state. Read on every sprint.autosprint/waypoint.md— the active waypoint, if present. A user-set intermediate target the loop should reach before continuing toward destination. State-shaped, same conventions as destination.md. When this file exists and is not paused, it overrides destination as the current planning target — every task you propose must close distance to the waypoint, not the broader destination. Only proposed tasks aimed at the waypoint count. If the file is missing, plan against destination as normal.autosprint/plan.md— the current plan, if it exists. Pay attention to:- Recent completed items (under
## Recent completed) — what just happened - Pending items (under
## Pending) — the current trajectory
- Recent completed items (under
autosprint/adr.md— architecture decision records: stable technical choices already made (libraries, patterns, schemas). Respect these. Do not propose tasks that undo or contradict an ADR without a very strong reason; if you must propose such a task, the task description should explicitly call out which decision it supersedes and why.autosprint/inputs/— supporting human-authored material (data model drafts, glossary, project description, design notes). Consulted on demand, not on every sprint. destination.md may name specific files here as load-bearing for certain task types — if so, follow those pointers. Otherwise list the folder if you need domain context for a specific task.- Relevant source files to verify the plan still makes sense given the current code
Authority hierarchy: waypoint.md (when active) > destination.md > inputs/. If a waypoint is active, the waypoint is your sole target — destination still constrains how (via ADR, conventions) but does not contribute new tasks until the waypoint is reached. If anything in inputs/ contradicts destination.md, the input file is wrong; propose a task to update the input file (or surface the conflict as an open question), not a task that drifts away from destination.md. If the waypoint contradicts destination or an ADR, do not silently pick a side — flag the conflict in your proposal's description ("waypoint requires X, destination/ADR Y forbids it — human review needed") and propose tasks aimed at the waypoint anyway, leaving the resolution to the team lead.
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-agent is an agent published in the GitHub repository haakonbull/autosprint (5 stars, last pushed 4d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,538 tokens. 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 2026-08-31.
