hermes-project-oracle

hermes-project-oracle is a skill for Claude Code, Codex from iruzen-dono/hermes-project-oracle. It costs 90 tokens per session (1,636 once invoked), scanned A, original, MIT.

A project-analysis tool that examines a codebase and creates context files such as AGENTS.md, CLAUDE.md, or an Obsidian note. These files describe the project's structure, technologies, conventions, and API routes for coding agents.

In plain words
What is it for?
Use it when starting work on a project, changing projects, or documenting its architecture. It can scan the project and generate the selected context-file format.
Why use it?
It reduces the time spent explaining an unfamiliar project to an agent and helps preserve conventions that may not be obvious from the code alone.

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

hermes-project-oracle 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 18d ago.

The scan reads SKILL.md. This mod also ships 13 executable files (scripts/oracle_generate.py, scripts/oracle_scan_lib/__init__.py, scripts/oracle_scan_lib/constants.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Project Oracle

Deep project scanner. It analyses a codebase and produces agent-ready context files (AGENTS.md, CLAUDE.md, Obsidian note) so any coding agent understands the project's stack, commands, conventions, and landmines in seconds. Zero dependencies — pure Python 3.11+ standard library, cross-platform.

Unlike a naive scan, this skill also captures human knowledge a scan cannot see: it interviews you for the project's intent and its known pitfalls, then embeds both in the generated file.

When to Use

  • First time on a project — generate its AGENTS.md / CLAUDE.md
  • A repo with implicit conventions an agent won't infer from code alone
  • Switching between projects — seed a clean context
  • Documenting architecture into an Obsidian vault
  • Onboarding a new developer or AI agent to an existing codebase

Prerequisites

  • Python 3.11+
  • git (optional — adds branch/remote/commit context)
  • An Obsidian vault (optional — only for the vault step)

Procedure

Follow these steps in order. Do not skip the interview — it is what makes the output genuinely useful.

1. Interview for intent and pitfalls

Ask the user (see references/interview-script.md for the full script):

  1. What does this project do, and for whom?
  2. What has broken or surprised you here before? (the landmines)
  3. Which commands do you actually run day-to-day?
  4. What must never be touched or overwritten?
  5. Which conventions are unwritten but real?

Save the answers as intent.json (see references/intent-example.json): {"purpose": "...", "pitfalls": [{"area": "...", "note": "..."}]}.

2. Scan

python <skill_dir>/scripts/oracle_scan.py --path <project> --output <project>/.oracle/

--output accepts a directory (.oracle/ or .oracle) or an explicit JSON file path. The directory form writes .oracle/scan-report.json. Keep the output inside the scanned project (as shown) so it stays out of version control. Flags: --depth N (tree depth, default 3), --skip-gitignore, --verbose.

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.
