What it costs to keep this loaded
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 | $0.00020 | $0.00496 |
| Opus 5.5 | $0.00008 | $0.00198 |
| Sonnet 5.5 | $0.00004 | $0.00099 |
| Haiku 4.5 | $0.00002 | $0.00050 |
Grade A, and why
slow-is-fast 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 20d 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 — 38 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Slow is Fast
Reduce the uncertainty that could change the implementation before committing to an approach. Use Research → Plan → Code at a depth proportional to the task; do not turn each phase into a mandatory deliverable or approval gate.
Research
- Inspect the relevant implementation, callers, and existing checks. Reuse findings already established in the conversation.
- Identify which unknowns affect correctness, compatibility, or scope. A local edit with an established pattern may need only nearby code; a cross-module change may need contract and lifecycle analysis.
- Check installed versions and official documentation when external behavior is uncertain or version-dependent. Choose available tools; no specific search provider or agent type is required.
- Delegate only a bounded question that can run independently alongside useful local work.
For a difficult reuse or dependency decision, consult research-patterns.md. It is not required reading for ordinary edits.
Plan
State the intended outcome, the constraints that affect the solution, and how completion will be assessed. Include the test mode from global AGENTS.md when verification requires an explanation.
Choose the simplest approach that meets the requirements and correctness constraints. Compare alternatives only when they differ meaningfully in behavior, maintenance cost, or reversibility. Do not invent extra options to fill a quota.
Keep bug fixes scoped to the failure. For features, finish the requested behavior and its necessary error paths without adding speculative capabilities. Identify consequential decisions before implementing them; ask only for unresolved decisions that materially change scope or risk.
Resolve unknowns that block a sound implementation. Describe bounded assumptions or verification limits for the rest. A numerical confidence score is not evidence and is not an exit requirement.
Implement and Finish
- Continue directly when the approach is clear and authorized. Do not wait for approval merely because planning is complete.
- Make reviewable changes, inspect intermediate results, and revise the approach if new evidence contradicts it.
- Follow the selected test mode. Fix failures caused by the change and rerun affected checks; broaden validation when new evidence or repository requirements justify it.
- Finish the requested delivery scope. Report the resulting behavior, observed validation, and concrete remaining limits.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

slow-is-fast is a skill published in the GitHub repository ahonn/dotfiles (63 stars, last pushed 6d ago), licensed MIT. It adds 20 tokens to every session and 496 once invoked, about $0.0001 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.
