WebCrypt copilot-instructions.md is an instructions file for GitHub Copilot from putervision/WebCrypt. It costs 2,464 tokens per session, scanned B, original, MIT.

A project guide for an AI coding assistant that records tasks, decisions, progress, and blockers in a shared state graph.

In plain words
What is it for?
It is for starting tasks, checking dependencies and blockers, documenting decisions, tracking new files, and marking completed work.
Why use it?
It helps the assistant understand the project before making changes and keeps important work context from being lost.

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 B, and why

WebCrypt copilot-instructions.md scanned grade B with 1 finding 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.

State Graph (state-graph-mcp)

This project tracks workflow state, tasks, design decisions, and blockers using state-graph-mcp.

1. Priority Order

Before doing any coding or investigation:

  1. get_project_summary — Always run this first to understand current project state, active branches, and overall progress.
  2. find_blockers — Identify any active blockers preventing progress.
  3. list_nodes — Find pending tasks, past decisions, or milestones.
  4. trace_dependencies — Trace what depends on or blocks a task.

2. When to Write to the Graph

You MUST update the graph as you work:

  • Starting a new task: Create a node with add_node(type: "task", title: "...").
  • Making a design or implementation decision: Document it with add_node(type: "decision", title: "...", metadata: { "rationale": "..." }).
  • Encountering a blocker: Record the blocker with add_node(type: "blocker", ...) and connect it to the blocked task using add_edge(type: "blocks", source_id: blocker_id, target_id: task_id).
  • Completing a task: Update the status to done using update_node(id: task_id, status: "done").
  • Creating/generating a new file: Create an artifact node with add_node(type: "artifact", ...) and connect it using add_edge(type: "produces").

3. Workflow Pattern

  1. Start of session: Run get_project_summary and find_blockers to align on current status.
  2. Task decomposition: Decompose user requests into tasks and add them to the graph.
  3. Execution: Mark tasks as "in_progress", document design decisions as they occur, and log blockers if you hit any obstacles.
  4. Resolution: Mark tasks as "done", document completed artifacts, and resolve blockers.

4. Codebase Seeding on Initialization

If the project was just initialized or is missing high-level structure (Plans, Milestones, Decisions):

  1. Inspect the Codebase: Read the README and core files to understand the roadmap and architecture.
  2. Scaffold the Roadmap: Create a plan node (e.g., "Project Roadmap") and add milestone nodes representing key target phases, connecting them using part_of edges.
  3. Scaffold Architecture: Create decision nodes representing core technical choices (e.g., choice of databases, frameworks) and link them to the milestones/tasks using decided_in edges.

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.
