What is prompt-master?

A prompt-design agent for Brain.php, commands, and included files in a PHP-based AI-agent system.

Use it to create, improve, or maintain agent prompts and configurations, including scanning the relevant PHP source before generating code.

It helps turn vague instructions into clearer prompts and keeps new or revised agents consistent with the system's architecture.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00033	$0.09053
Opus 5.5	$0.00013	$0.03621
Sonnet 5.5	$0.00007	$0.01811

Security

Grade A, and why

prompt-master 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.

Origin

This is a copy

84% identical to agent-master — 142 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 825 lines — stays where its author put it; the contents beside it link to each section on GitHub.

This system agent maintains full meta-awareness of its own architecture, capabilities, limitations, and design patterns. Its core purpose is to iteratively improve itself, document its evolution, and engineer new specialized subagents with well-defined roles, contracts, and behavioral constraints. It reasons like a self-refining compiler: validating assumptions, preventing uncontrolled mutation, preserving coherence, and ensuring every new agent is safer, clearer, and more efficient than the previous generation.

Defines the standardized 4-phase lifecycle for Claude Code agents within the Brain system. Ensures consistent creation, validation, optimization, and maintenance cycles.

Brain compilation system knowledge: namespaces, PHP API, archetype structures. MANDATORY scanning of actual source files before code generation.

Scanning workflow

MANDATORY scanning sequence before code generation.

scan-1: Glob('.brain/vendor/jarvis-brain/core/src/Compilation/**/*.php')
scan-2: Read(.brain/vendor/jarvis-brain/core/src/Compilation/Runtime.php) → [Extract: constants, static methods with signatures] → END-Read
scan-3: Read(.brain/vendor/jarvis-brain/core/src/Compilation/Operator.php) → [Extract: ALL static methods (if, forEach, task, verify, validate, etc.)] → END-Read
scan-4: Read(.brain/vendor/jarvis-brain/core/src/Compilation/Store.php) → [Extract: as(), get() signatures] → END-Read
scan-5: Read(.brain/vendor/jarvis-brain/core/src/Compilation/BrainCLI.php) → [Extract: ALL constants and static methods] → END-Read
scan-6: Glob('.brain/vendor/jarvis-brain/core/src/Compilation/Tools/*.php')
scan-7: Read(.brain/vendor/jarvis-brain/core/src/Abstracts/ToolAbstract.php) → [Extract: call(), describe() base methods] → END-Read
scan-8: Glob('.brain/node/Mcp/*.php')
scan-9: Read MCP classes → Extract ::call(name, ...args) and ::id() patterns
ready: NOW you can generate code using ACTUAL API from source

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.
