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 | $0.00689 | $0.00689 |
| Opus 5.5 | $0.00276 | $0.00276 |
| Sonnet 5.5 | $0.00138 | $0.00138 |
| Haiku 4.5 | $0.00069 | $0.00069 |
Grade A, and why
Tailor CLAUDE.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.
This is a copy
100% identical to Tailor copilot-instructions.md — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts

AI Agent Guidance (Powered by Tailor)
This repository uses Tailor for project intelligence, Spec-Driven Development, and Reuse-First engineering discipline.
Non-Negotiable Directives
1. Cold-Start & Project Memory Hierarchy
- Always consult
.ai/CONSTITUTION.mdand.ai/INDEX.mdfirst before planning or making non-trivial modifications. - Cold-Start Fallback: If the
.ai/directory does not exist yet, do NOT invent arbitrary conventions. Inspectpackage.json(or workspace manifests) and active source files directly to determine established patterns, and suggest runningnpx @amanktyr/tailor initto establish project memory.
2. Mandatory Guardrail: Zero Unrequested Styling & Redesign
- STRICTLY PROHIBITED: NEVER add, alter, or inject CSS, styling frameworks, inline styles, gradients, glassmorphism, or animations unless the user explicitly requested visual or styling changes.
- When working on logic, bugfixes, refactoring, or state management: preserve existing visual markup and styling tokens untouched.
- When writing UI components: strictly reuse existing design tokens, components, and CSS classes from the codebase or
.ai/UI.md. Never invent new arbitrary classes, hex colors, or custom styling rules. - If the project has no styling system and no styling is requested, output clean, unstyled semantic HTML.
3. Mandatory Guardrail: Zero Bloat & Minimal Diff Discipline (Anti-Slop)
- Implement only the minimal code required to satisfy the user's specific request.
- NO speculative abstractions: Do not create premature wrapper classes, generic factories, or speculative interfaces for one-off operations.
- NO dummy/mock data: Never add mock datasets, fake user lists, or placeholder fixtures in production code.
- NO filler comments: Never write redundant explanatory comments (e.g.
// Here we define the function) that state the obvious. Only document why non-obvious business logic or security decisions exist.
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.
