hyper-document

A documentation-maintenance guide for updating project files after code, skill, or framework changes.

In plain words
What is it for?
Inspecting changed files and updating the relevant documentation, memory files, and skill information based on the actual implementation.
Why use it?
It reduces mismatches between the implementation and documents such as the README, changelog, guides, and agent instructions.

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

hyper-document 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 yesterday.

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.

Hyper-Document

This skill updates the full documentation suite after changes to the codebase, skills, or framework structure. It reads actual implementation before writing anything — existing documentation is treated as potentially stale.


When to use this skill

  • After completing a feature, bug fix, refactor, or skill change.
  • When README.md, CHANGELOG.md, docs/, or other docs are out of sync with the codebase.
  • When the user explicitly runs /hyper-document.

Step 1 — Identify What Changed

Run the following to understand scope:

git log --oneline -10
git diff HEAD~1 --name-only

Identify:

  • Which files were modified, added, or deleted.
  • Whether the change is user-facing (affects README, CHANGELOG, docs) or internal (affects memory files, skills-info).
  • Whether any skills were added, renamed, or removed.

Step 2 — Read Before Writing

CRITICAL: Do NOT trust existing documentation. Read the actual implementation.

  • Read every changed file before updating any doc.
  • Note discrepancies between existing docs and actual behavior.
  • Never assume — verify.

Step 3 — Update Documentation by Target

Work through each target below. Skip targets that are clearly unaffected by the change.


README.md

Purpose: Entry point for new users and project overview.

Update when: Architecture changes, new features, new IDE support, install/uninstall changes, workflow changes, new slash commands, or directory structure changes.

Style rules:

  • Lead with what it does, not how it works.
  • Use H2 (##) for top-level sections, H3 (###) for subsections.
  • Prefer tables for structured comparisons (IDE support, installed paths, commands).
  • Use fenced code blocks with language tags for all commands and examples.
  • Bullet lists for feature enumerations; numbered lists for sequential steps only.
  • No marketing language. No "powerful", "robust", "seamless".
  • Every slash command mentioned must use the hyper- prefix (e.g. /hyper-architect).
  • Callout blocks (> **Note:**) for caveats, naming conventions, and non-obvious behaviors.

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.

hyper-document is a skill published in the GitHub repository tjmustard/Hypergraph-Coding-Agent-Framework (2 stars, last pushed 1mo ago), licensed MIT. It adds 55 tokens to every session and 1,876 once invoked, about $0.0003 per session on Opus 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.
