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 | $0.00823 | $0.00823 |
| Opus 5.5 | $0.00329 | $0.00329 |
| Sonnet 5.5 | $0.00165 | $0.00165 |
| Haiku 4.5 | $0.00082 | $0.00082 |
Grade A, and why
flins AGENTS.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 1mo 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 — 123 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Use Bun exclusively. Do NOT use npm, pnpm, or yarn under any circumstances.
Plan Mode
When operating in Plan Mode:
-
Produce concise, execution-focused plans.
-
Clarity is required; verbosity is not.
-
Do not include explanations, prose, or filler.
-
Output only concrete steps.
-
Every plan MUST end with a section titled “Unresolved Questions”.
-
Include only questions that materially block execution.
-
If there are no blockers, explicitly write:
Unresolved Questions: None.
Failure to follow this structure is not allowed.
Code Style & Generation Rules
All generated code must follow these rules:
- Code must be self-explanatory.
- Do not use comments.
- Intent must be expressed through naming, structure, and composition only.
Strict consistency is required across:
- File structure
- Module boundaries
- Naming conventions
- Architectural patterns
Before writing any code:
- Explore the existing project.
- Understand the directory layout, conventions, abstractions, and dependency patterns.
When adding new code:
- Place it only in logically correct locations.
- Do not introduce new patterns unless strictly necessary.
Mandatory Skill Enforcement (Zero Tolerance)
All rules below are NON-NEGOTIABLE.
If any applicable skill is not used, the response is INVALID.
There are:
- No excuses
- No interpretation
- No flexibility
Rules:
- If a condition applies → use the skill.
- If unsure → assume it applies and use the skill.
- If multiple conditions apply → use all relevant skills.
- Do not proceed with an answer until all required skills are applied.
Skill Requirements
Planning & Scope
- Skill(avoid-feature-creep) Required for feature planning, scope discussion, MVPs, roadmaps, and backlogs.
CLI
- Skill(commander-guidelines) Required for any CLI with commands, flags, options, arguments, or subcommands.
- Skill(clack-guidelines) Required for interactive CLI behavior: prompts, confirmations, selections, spinners, progress, autocomplete.
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.
- 1mo ago First seen · 123 lines · 823 tokens per session scan A 7b110b394c52
flins AGENTS.md is an instructions file published in the GitHub repository powroom/flins (39 stars, last pushed 6mo ago), licensed MIT. It adds 823 tokens to every session, about $0.0033 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 2026-08-30.
