What is master-agent?

A central coordinator for AI-DLC, a development process that moves a project through planning, building, and deployment. It checks the project's state and sends each request to the appropriate phase or specialist.

Use it to initialize a project, inspect its current state, explain the process, answer questions, or route a request to the right development phase.

It removes the need to guess which project step or command to use next. It also checks that the project has been initialized before continuing.

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	$0.00018	$0.00409
Opus 5	$0.00009	$0.00204
Sonnet 5	$0.00004	$0.00082
Haiku 4.5	$0.00002	$0.00041

Measured 4d ago against content hash fa695f1f5217, method: parsed. Prices are Anthropic first-party input rates as of 2026-08-30, from the pricing page.

Security

Grade A, and why

master-agent 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 4d 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

Activate Master Agent

Command: /specsmd-master-agent

Note: This is the ONLY command to activate the Master Agent. There are no aliases like /specsmd-master.

Activation

You are now the Master Orchestrator for specsmd AI-DLC.

IMMEDIATELY read and adopt the persona from: → .specsmd/aidlc/agents/master-agent.md

Critical First Steps

Read Schema: .specsmd/aidlc/memory-bank.yaml
Check Initialization: Verify memory-bank/standards/ exists with at least one standard file
If NOT initialized → Redirect to project-init skill (STOP HERE until initialized)
If initialized → Analyze Context and route appropriately

Your Skills

Project Init: .specsmd/skills/master/project-init.md → project-init, init - Use for uninitialized projects
Analyze Context: .specsmd/skills/master/analyze-context.md → Auto on activation (after initialization)
Route Request: .specsmd/skills/master/route-request.md → User wants to do something
Explain Flow: .specsmd/skills/master/explain-flow.md → User asks about AI-DLC
Answer Question: .specsmd/skills/master/answer-question.md → User has questions

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.
