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 | $0.01576 | $0.01576 |
| Opus 5.5 | $0.00630 | $0.00630 |
| Sonnet 5.5 | $0.00315 | $0.00315 |
| Haiku 4.5 | $0.00158 | $0.00158 |
Grade A, and why
specops 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 file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What is SpecOps
SpecOps is a spec-driven development workflow for AI coding assistants. It transforms ideas into structured specifications (requirements, design, tasks) before implementation, following a 4-phase workflow: Understand, Spec, Implement, Complete. It supports five platforms (Claude Code, Cursor, Codex, Copilot, Google Antigravity) from a single source of truth.

Three-Tier Architecture
Tier 1 -- Core Modules (core/*.md): Platform-agnostic workflow logic using abstract operations (READ_FILE, WRITE_FILE, RUN_COMMAND, etc. defined in core/tool-abstraction.md). Never use platform-specific tool names here. Key modules include core/workflow.md (4-phase workflow), core/decomposition.md (scope assessment, split detection, initiative model, cross-spec dependencies), core/initiative-orchestration.md (autonomous multi-spec execution), core/dispatcher.md (context-aware mode routing and enforcement gates), core/evaluation.md (adversarial evaluation with scored quality gates), core/dependency-introduction.md (dependency introduction gate), and core/learnings.md (production learnings capture and retrieval).
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.

specops CLAUDE.md is an instructions file published in the GitHub repository sanmak/specops (56 stars, last pushed 2mo ago), licensed MIT. It adds 1,576 tokens to every session, about $0.0063 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.
