init-claude-md

init-claude-md is a skill for Claude Code from rossumai/claude-marketplace. It costs 107 tokens per session (2,763 once invoked), scanned A, original, MIT.

A workflow that creates a project-specific CLAUDE.md file for a pulled Rossum prd2 project. CLAUDE.md is a project instruction file that Claude Code reads automatically in future sessions.

In plain words
What is it for?
Inspecting a local project and documenting its environments, queues, hooks, schemas, integration targets, commands, and editing or deployment rules.
Why use it?
It records the project's Rossum conventions and structure so future sessions do not have to rediscover how files, commands, environments, and deployment approvals work.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: mentions CLAUDE.md; mentions Claude Code.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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

init-claude-md 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.

The scan reads SKILL.md. This mod also ships 4 executable files (inspect.py, tests/fixtures/coupa/dev-env/hooks/coupa_export/code.py, tests/fixtures/sap/dev-env/hooks/sap_idoc_export/code.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.

How it starts

The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Initialize CLAUDE.md for a Rossum prd2 Project

Path or context: $ARGUMENTS

What this skill does

Generates a CLAUDE.md at the root of a pulled prd2 project so future Claude Code sessions know it's a Rossum implementation and apply the right safety rules (edit .py not JSON, never push/deploy without approval, MDH targets are enums).

The auto-generated portion is wrapped in <!-- BEGIN/END rossum-sa:init-claude-md auto-generated --> markers. Re-running this skill rewrites only the marked block; the "Project-Specific Notes" section below the markers is preserved.

Why a project-specific CLAUDE.md

Anthropic recommends CLAUDE.md for project memory — it is auto-loaded at the start of each Claude Code session. Without one, every session has to rediscover Rossum conventions (edit .py not JSON, prd2 commands, safety rules, where queues/hooks/formulas live). A pre-filled file removes that friction.

Best-practices sections (from the source article that motivated this skill):

  1. Project Overview — what the implementation is, what it optimizes for
  2. Tech Stack — explicit list of what's in use and what to avoid
  3. Architecture — real directory layout, where new things go
  4. Coding Conventions — hard rules (not vague "write clean code")
  5. Commands — exact commands, not paraphrases
  6. Safety Rules — confirmation gates for destructive ops
  7. File Placement Rules — when to create new files vs. edit existing
  8. Testing & Quality — how "done" is validated
  9. Recommended Skills — pointers to relevant rossum-sa:* skills
  10. Project-Specific Notes — human-curated area

Workflow

Step 1: Resolve the project directory

If $ARGUMENTS is a path, use it. Otherwise use the current working directory. Pass this directory straight to the inspector (Step 2) — the inspector detects the deployment tool via its marker file and decides whether the project is supported, so don't pre-gate on specific files here. (The single "not supported" stop lives in Step 2.)

Step 2: Run the inspector

What ships with it

26 files beside SKILL.md 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.
