Hypergraph-Coding-Agent-Framework: Skill for Claude Code

.agents/skills/hyper-discover/SKILL.md

discover is a skill for Claude Code, Codex from tjmustard/Hypergraph-Coding-Agent-Framework. It costs 18 tokens per session (415 once invoked), scanned A, original, MIT.

A codebase discovery tool that scans a repository and maps its folders, functions, classes, components, imports, and exports into an architecture.yml hypergraph. A hypergraph is a structured map of connected parts and relationships.

In plain words
What is it for?
Creating or updating an architecture map, documenting repository structure, and tracing dependencies between files and code elements.
Why use it?
It reduces the manual work of understanding an unfamiliar repository and records how its parts depend on one another.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is tjmustard/Hypergraph-Coding-Agent-Framework's own configuration. It tells Claude Code and Codex how to work on Hypergraph-Coding-Agent-Framework itself, so it is not a mod to install elsewhere.

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

discover 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 2mo 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

ROLE: The Discovery Agent

Your objective is to perform a recursive scan of the existing repository to map its topological structure into the architecture.yml hypergraph schema.

CRITICAL RULES

  1. Top-Down Discovery: Start with the directory structure to identify "Module" nodes. Then drill into files to identify "Atomic" nodes (functions, classes, components).
  2. Dependency Mapping: Pay strict attention to imports and exports. These define the depends_on edges in the YAML.
  3. Semantic Analysis: Do not just list files. Read the code to provide a concise description of the node's semantic purpose.

EXECUTION PHASES

[PHASE 1: Directory Mapping]

  • Identify the major folders and map them to "Module" dimension nodes in the hypergraph.

[PHASE 2: Atomic Extraction]

  • For each major file, identify the core functions or classes. Map these to "Atomic" dimension nodes.
  • Link them to their parent Module via the implements edge.

[PHASE 3: Edge Detection]

  • Trace the data flow. If File A imports File B, File B is a dependency. Map this to the depends_on edge.

OUTPUT

Update or create spec/compiled/architecture.yml. Set all newly discovered nodes to status: clean. Output a summary of the system's topological density (number of modules vs. atomic nodes).

Final Action:

  • If creating the file from scratch, save the compiled YAML to spec/compiled/architecture.yml.
  • If appending/modifying an existing graph, you MUST execute python .agents/scripts/hypergraph_updater.py spec/compiled/architecture.yml [modified_node_ids] via your terminal tool to properly propagate the Blast Radius.
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.

discover is a skill published in the GitHub repository tjmustard/Hypergraph-Coding-Agent-Framework (2 stars, last pushed 1mo ago), licensed MIT. It adds 18 tokens to every session and 415 once invoked, about $0.0001 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.
