Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.01557 | $0.01557 |
| Opus 5 | $0.00779 | $0.00779 |
| Sonnet 5 | $0.00311 | $0.00311 |
| Haiku 4.5 | $0.00156 | $0.00156 |
Grade A, and why
MCP_DinCoder 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 2d 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.

This file provides guidance to AI agents when working with code in this repository.
Project Overview
Spec-Driven MCP Orchestrator - Model Context Protocol server with Streamable HTTP transport, exposing Spec Kit tools (specify, plan, tasks) for AI-assisted spec-driven development workflows.
Critical Requirements
- Protocol: MCP Streamable HTTP (Protocol Revision 2025-03-26)
- TypeScript SDK: @modelcontextprotocol/sdk v1.17.5+
- Node.js: >=20
- Transport: HTTP only (STDIO deprecated Sept 7, 2025)
- TypeScript Config: MUST use module/moduleResolution: "NodeNext"
⚠️ MCP Prompts - CRITICAL UNDERSTANDING
MCP prompts are workflow orchestrators for AI agents, NOT user-typed commands.
How They Work
- AI Discovery: Agents discover prompts via
prompts/listJSON-RPC call - AI Invocation: Agents call
prompts/getprogrammatically when relevant - User Experience: Users describe goals in natural language; AI uses appropriate prompt automatically
Example
User: "Let's start a new project called task-manager"
Behind the scenes:
- AI recognizes this matches
start_projectprompt - AI invokes prompt programmatically
- AI receives workflow instructions
- AI guides user through setup
User sees: Natural conversation (NOT a slash command)
Platform Behavior
- Claude Code:
@= files,/= native commands, MCP prompts = invisible - VS Code/Copilot/Cursor: MCP prompts integrated into agent workflows
Registered Prompts (v0.4.0+)
| Prompt | Purpose | Arguments |
|---|---|---|
start_project |
Initialize new project | projectName, agent (optional) |
create_spec |
Create specification | description |
generate_plan |
Generate implementation plan | specPath (optional) |
create_tasks |
Break down into tasks | planPath (optional) |
review_progress |
Generate progress report | None |
validate_spec |
Check specification quality | specPath (optional) |
next_tasks |
Show actionable tasks | limit (optional) |
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.

MCP_DinCoder CLAUDE.md is an instructions file published in the GitHub repository flight505/MCP_DinCoder (2 stars, last pushed 10mo ago), licensed MIT. It adds 1,557 tokens to every session, about $0.0078 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
