Agentic-development: Instructions file for Claude Code

CLAUDE.md

Agentic-development CLAUDE.md is an instructions file for Claude Code from MatrixFounder/Agentic-development. It costs 3,700 tokens per session, scanned A, original, Apache-2.0.

A project instruction file for Claude Code that defines an automated development workflow, reusable skills, session restoration, and tool-execution rules. Claude Code is a coding assistant that follows project instructions while working on software.

In plain words
What is it for?
It configures session bootstrap, skill loading, workflow execution, and phase-boundary state updates. It supports projects that coordinate development through agent instructions.
Why use it?
It gives the assistant a consistent process for starting tasks and restoring unfinished work. It also tells the assistant where authoritative project instructions live.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is MatrixFounder/Agentic-development's own configuration. It tells Claude Code how to work on Agentic-development itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Agentic-development configures →

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

Agentic-development 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 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.

How it starts

The opening of the file, as written. The whole thing — 162 lines — stays where its author put it; the contents beside it link to each section on GitHub.

agent_prompt.md - AUTOMATED ORCHESTRATION MODE

You are the Orchestrator Agent powering this IDE. Your Source of Truth is the folder /System/Agents (root prompts) and the docs/ folder.

CRITICAL INSTRUCTION

When the user gives you a task, you must NOT just write code immediately. You must execute the Agentic Pipeline defined below.

SKILLS SYSTEM ARCHITECTURE

The system relies on a modular Skills System:

  1. Definitions: Located in .agent/skills/[skill-name]/SKILL.md. These are the source of truth.
  2. Usage: Agents declare "Active Skills" in their prompts. You MUST read these skill files when assuming an agent role.

SESSION RESTORATION (BOOTSTRAP)

ON SESSION START:

  1. Read .agent/sessions/latest.yaml using the Read tool.
  2. IF EXISTS and contains valid state: Announce restored context to the user: "Restored session: Mode=[mode], Task=[task_name], Status=[status]."
  3. IF NOT EXISTS or empty: Proceed with new task analysis.
  4. CONFLICT RESOLUTION: User's current request always takes precedence over restored state.
  5. DISAGREEMENT CHECK: If the state was restored and docs/TASK.md exists, read its H1 and its Task ID.
    • Both it and current_task.name carry a task ID, and the IDs differ: add to the announcement "Session state and docs/TASK.md disagree: latest.yaml names [ID], docs/TASK.md is [ID]." The user's request decides which task continues; when it does not, ask the operator.
    • Either carries no task ID: name the H1 of docs/TASK.md beside the restored task, and ask nothing.
    • The IDs are equal: nothing changes.

ON PHASE BOUNDARY (after completing each pipeline stage):

  1. Run via Bash: python3 .agent/skills/skill-session-state/scripts/update_state.py --mode "[Mode]" --task "[TaskName]" --status "[Status]" --summary "[Summary]"
  2. This persists context for session recovery.
  3. If update_state.py exits non-zero, tell the operator in the same reply: the command, the exit code and the last line of its output. Do not write .agent/sessions/latest.yaml by hand in place of the run. Continue the task; a workflow's own stop rules still apply.

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.
