hads

hads is a skill for Claude Code, Codex from RudyCity/superagent. It costs 43 tokens per session (1,572 once invoked), scanned A, a copy of hads, MIT.

A guide to HADS, a Markdown format for technical documents that separates authoritative specifications, notes, verified bugs, and uncertain information for people and AI systems.

In plain words
What is it for?
Use it to write, convert, validate, and optimize technical documentation in HADS format.
Why use it?
It helps readers identify which parts of a document are facts, context, known problems, or unverified claims, while keeping documentation efficient for AI tools.

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

hads 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 5d 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.

Origin

This is a copy

98% identical to hads — 3 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

HADS Claude Skill

Version 1.0.0 · Human-AI Document Standard · 2026 · HADS 1.0.0


AI READING INSTRUCTION

This skill teaches Claude how to read, generate, and validate HADS documents. Read all [SPEC] blocks before responding to any HADS-related request. Read [NOTE] blocks if you need context on intent or edge cases.


1. WHAT IS HADS

[SPEC]

  • HADS = Human-AI Document Standard
  • Convention for Markdown technical documentation
  • Four block types: **[SPEC]**, **[NOTE]**, **[BUG]**, **[?]**
  • Every HADS document requires: H1 title, version declaration, AI manifest
  • AI manifest appears before first content section, tells AI what to read/skip
  • File extension: .md — standard Markdown, no tooling required

2. BLOCK TYPES

[SPEC]

**[SPEC]**   Authoritative fact. Terse. Bullet lists, tables, code. AI reads always.
**[NOTE]**   Human context, history, examples. AI may skip.
**[BUG]**    Verified failure + fix. Required fields: symptom, cause, fix. Always read.
**[?]**      Unverified / inferred. Lower confidence. Always flagged.

Block tag rules:

  • Bold, on its own line: **[SPEC]**
  • Content follows immediately (no blank line between tag and content)
  • Multiple blocks of different types allowed per section
  • Titled BUG blocks allowed: **[BUG] Short description**
  • No nesting of blocks inside blocks

3. REQUIRED DOCUMENT STRUCTURE

[SPEC]

# Document Title
**Version X.Y.Z** · Author · Date · [metadata]

---

## AI READING INSTRUCTION

Read `[SPEC]` and `[BUG]` blocks for authoritative facts.
Read `[NOTE]` only if additional context is needed.
`[?]` blocks are unverified — treat with lower confidence.

---

## 1. First Section

**[SPEC]**
...

Required elements in order:

  1. H1 title
  2. **Version X.Y.Z** in header (first 20 lines)
  3. AI manifest section before first content section
  4. Content sections (H2), subsections (H3)

4. HOW CLAUDE READS HADS

[SPEC] When encountering a HADS document:

  1. Find and read the AI manifest first
  2. Read all [SPEC] blocks — these are ground truth
  3. Read all [BUG] blocks — always, before generating any code or config
  4. Read [NOTE] blocks only if [SPEC] is insufficient to answer the query
  5. Treat [?] content as hypothesis — note uncertainty in response

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.
