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

cadence 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

cadence

This repository develops the cadence plugin — a domain-neutral, discussion-driven project workflow plugin that records / consolidates / retrieves AI session decisions into project archives.

The cadence plugin is itself developed using cadence conventions. See skills/cadence-bootstrap/SKILL.md for the active workflow contract (记 / 整 / 查 三阶段, _INDEX.md / _ACTIVE.md state contract, and the three-stage recording decision: acceptance / durable semantic delta / impact profile).

When working in this repo with any AI agent (Claude Code / Codex CLI / Cursor / etc.), the cadence-bootstrap protocol applies. CC harness reads it via SessionStart hook injection; Codex / other harnesses match it via skill description on session start.

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.
