What is MCP_DinCoder copilot-instructions.md?

A set of instructions and tools for spec-driven development, where you describe and validate what to build before making an implementation plan. It organizes specifications, clarifications, plans, and tasks in a `.dincoder/` directory.

It helps initialize a project, write and refine specifications, check the plan against them, create task lists, inspect dependencies, search and filter tasks, and track progress.

It reduces unclear requirements and mismatches between what a project should do and how it will be built.

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	$0.00749	$0.00749
Opus 5.5	$0.00300	$0.00300
Sonnet 5.5	$0.00150	$0.00150
Haiku 4.5	$0.00075	$0.00075

Security

Grade A, and why

MCP_DinCoder copilot-instructions.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 1mo 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.

DinCoder Spec-Driven Development

This project uses DinCoder for spec-driven development workflows.

MCP Tools Available

The DinCoder MCP server provides tools for structured development:

Project Initialization

specify_start - Initialize .dincoder/ directory
prereqs_check - Verify environment setup

Specification Phase

specify_describe - Create detailed specification
spec_validate - Check specification quality
spec_refine - Update specific sections
clarify_add/resolve/list - Manage clarifications

Planning Phase

plan_create - Generate technical implementation plan
artifacts_analyze - Verify spec-plan alignment

Task Management

tasks_generate - Create actionable task list
tasks_visualize - Show dependency graphs (Mermaid/Graphviz/ASCII)
tasks_filter - Smart filtering (next, frontend, backend, ready, cleanup)
tasks_search - Fuzzy search across tasks
tasks_stats - Progress analytics and charts
tasks_tick - Mark single task complete
tasks_tick_range - Batch completion (T001-T005 syntax)

Workflow

Specify - Define what to build
- Run specify_start to initialize
- Run specify_describe to create spec.md
- Run spec_validate to ensure quality
Plan - Design how to build it
- Run plan_create to generate plan.md
- Run artifacts_analyze to verify alignment
Execute - Build following tasks
- Run tasks_generate to create tasks.md
- Run tasks_filter with preset "next" to see actionable items
- Mark complete with tasks_tick or tasks_tick_range
Track - Monitor progress
- Run tasks_stats for progress analytics
- Run tasks_visualize for dependency graphs

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.
