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 | $0.03028 | $0.03028 |
| Opus 5.5 | $0.01211 | $0.01211 |
| Sonnet 5.5 | $0.00606 | $0.00606 |
| Haiku 4.5 | $0.00303 | $0.00303 |
Grade A, and why
shep 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 14d 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 — 195 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
Guidance for Claude Code working in this repository.
Project
@shepai/cli — Autonomous AI-native SDLC platform — run parallel AI agents in isolated worktrees to automate the development cycle from idea to deploy.
Spec Workflow
All feature work MUST begin with /shep-kit:new-feature. See spec-driven-workflow.
/shep-kit:new-feature → /shep-kit:research → /shep-kit:plan → /shep-kit:implement → /shep-kit:commit-pr
Specs live in specs/NNN-feature-name/. Edit YAML only — Markdown is auto-generated.

Architecture
Clean Architecture — four layers in packages/core/src/ (dependencies point inward):
domain/— Core business logic, no external depsapplication/— Use cases, output port interfacesinfrastructure/— External concerns: DB, agents, servicespresentation/— CLI, TUI, Web UI (src/presentation/)
See clean-architecture.
Mandatory Rules
- MANDATORY — TDD: Write failing tests FIRST (RED → GREEN → REFACTOR). Every plan phase must define explicit TDD cycles. See tdd-guide.
- MANDATORY — TypeSpec-first: Domain models defined in
tsp/. Runpnpm tsp:compileto generatepackages/core/src/domain/generated/output.ts. Never edit generated files. See typespec-guide. - MANDATORY — Agent resolution: No component may hardcode an agent type. All resolution flows through
IAgentExecutorProvider. See AGENTS.md. - MANDATORY — Storybook stories: Every web UI component MUST have a colocated
.stories.tsxfile. Commits without stories will be rejected. - MANDATORY — Spec-driven: All features start with
/shep-kit:new-feature. No implementation without a spec. - MANDATORY — Own every failure: You are the ONLY developer. Every test failure, CI failure, and security scan failure is YOUR responsibility. NEVER use the words "unrelated", "pre-existing", or "not our changes". See integrity rules.
- MANDATORY — Read LESSONS.md: You MUST read
LESSONS.mdat the start of every session before writing any code. It contains hard-won lessons from past mistakes. Ignoring it means repeating failures that have already been solved.
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.

shep CLAUDE.md is an instructions file published in the GitHub repository shep-ai/shep (267 stars, last pushed yesterday), licensed MIT. It adds 3,028 tokens to every session, about $0.0121 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.
