Security

Grade A, and why

daymade-skill 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 today.

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

{
  "name": "daymade-skill",
  "description": "Daymade skills core suite. Bundles skill creation, quality review, real Claude/Codex Skill-surface governance, suite-migration reconciliation, and marketplace development tooling under one shared namespace. Skill governance separates canonical source, installed inventory, discovery policy, the fresh model-visible catalog, and router-resolved cold resources instead of optimizing cache counts; it preserves Claude's official versioned-cache lifecycle and verifies selected entries in the real host prompt. Skill verification separates risk classification from evaluation spend: bounded fixes use targeted checks, narrow behavior changes use sampled replays, and paired baselines, graders, benchmarks, or a viewer run only after explicit user authorization or a decision-bearing evidence plan plus opt-in; that authorization does not change the risk tier. Existing-skill edits retain an old-vs-new capability audit and content-bound packaging attestation so prompt compression cannot silently delete runtime contracts. When the official skill-creator plugin is also installed, skill-creator detects the coexistence and offers a consent-based, reversible SessionStart routing hook so the daymade edition wins deterministically; on machines without the official plugin nothing is ever installed.",

Contents

What it installs

The manifest is a name and a version. 4 skills travel with it, and installing the plugin installs all of them — 485 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Files

What ships with it

1 file beside marketplace.json#daymade-skill in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
