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 | $0.02338 | $0.02338 |
| Opus 5.5 | $0.00935 | $0.00935 |
| Sonnet 5.5 | $0.00468 | $0.00468 |
| Haiku 4.5 | $0.00234 | $0.00234 |
Grade A, and why
handoff 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 9d 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 — 156 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file records shared contributor guidance. Claude Code reads it directly;
Codex is pointed here by AGENTS.md.
What this repo is
This repo is a Claude Code and local Codex plugin named handoff. It is not an application.
It ships a hook-driven project-memory system plus an owned development
workflow layer that other repos install. There is no build step and no
dependency tree — the deliverable is Python hook scripts (stdlib only), a skill
set, and a template tree. CI (.github/workflows/ci.yml) runs the stdlib smoke
tests in tests/test_hooks.py on every push/PR.
The skill set (v1.2.0+): setup (scaffolding), workflow (the 6-phase,
risk-tiered pipeline — the constitution that owns sequencing), and thirteen
technique skills (brief, plan, design, tdd, debug, architecture,
delegate, verify-done, security, browser-qa, ship, learn,
grill-me) forked
from MIT-licensed superpowers, mattpocock-skills, gstack, and rampstack-skills
with all cross-pack orchestration stripped (see ATTRIBUTION.md). When editing
a technique skill, never reintroduce pack-style enforcement preambles or
cross-skill process handoffs — workflow alone decides sequencing and tiering.
Do not confuse the two layers:
- The plugin (
hooks/,skills/,.claude-plugin/,.codex-plugin/) — what a developer installs into Claude Code or local Codex. Editing here changes behavior for every repo that uses it. - The
templates/tree — the payload thesetupskill copies into a target repo as.handoff/. This is committed to the target repo so memory travels with the code. Editing here changes what newly-set-up repos get; it does not affect already-set-up repos.
Runtime model (how the pieces connect)
Everything is driven by three hooks registered in hooks/hooks.json (auto-loaded
because it lives at hooks/hooks.json — the plugin manifest deliberately does not
declare a hooks field; see commit 1844000). Each hook is a thin python3 entry that
imports shared logic from hooks/_common.py:
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.

handoff CLAUDE.md is an instructions file published in the GitHub repository AbdurRafay2004/handoff (4 stars, last pushed 10d ago), licensed MIT. It adds 2,338 tokens to every session, about $0.0094 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 2026-08-31.
