Token cost

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.

Security

Grade A, and why

Tailor 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.

What it actually says

Agent Instructions for @amanktyr/tailor

This repository uses Tailor for project intelligence and memory.

Non-Negotiable Directives

  1. Constitution & Project Memory First: Always consult .ai/CONSTITUTION.md and .ai/INDEX.md before making non-trivial changes.
  2. Zero Unsolicited Styling: NEVER add, alter, or inject CSS, Tailwind classes, colors, gradients, or restyle components unless explicitly requested.
  3. Zero Bloat & Speculative Code: Minimal diff discipline; no mock datasets, premature abstractions, or obvious filler comments.
  4. Reuse-First Decision Ladder: Search existing components, hooks, and utilities before writing new code.
  5. Pragmatic Simplicity: Prefer standard library and native platform APIs over trivial external dependencies.
  6. Spec-Driven Discipline: For non-trivial features, follow the specification lifecycle (specs/<id>/spec.md -> plan.md -> tasks.md).
  7. Truthful Verification: Verify changes with targeted tests; never fabricate test passes.
Changes

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.
