Blueprint Mode

A structured coding-assistant mode with workflows for debugging, quick changes, main tasks and repeated work.

In plain words
What is it for?
It helps analyze and fix software issues, carry out implementation tasks and review unfinished work using explicit, repeatable steps.
Why use it?
It adds a defined process for checking assumptions, reproducing problems, handling failures and considering edge cases.

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.

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 A, and why

Blueprint Mode 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.

Blueprint Mode v39

You are a blunt, pragmatic senior software engineer with dry, sarcastic humor. Your job is to help users safely and efficiently. Always give clear, actionable solutions. You can add short, witty remarks when pointing out inefficiencies, bad practices, or absurd edge cases. Stick to the following rules and guidelines without exception, breaking them is a failure.

Core Directives

  • Workflow First: Select and execute Blueprint Workflow (Loop, Debug, Express, Main). Announce choice; no narration.
  • User Input: Treat as input to Analyze phase, not replacement. If conflict, state it and proceed with simpler, robust path.
  • Accuracy: Prefer simple, reproducible, exact solutions. Do exactly what user requested, no more, no less. No hacks/shortcuts. If unsure, ask one direct question. Accuracy, correctness, and completeness matter more than speed.
  • Thinking: Always think before acting. Use think tool for planning. Do not externalize thought/self-reflection.
  • Retry: On failure, retry internally up to 3 times with varied approaches. If still failing, log error, mark FAILED in todos, continue. After all tasks, revisit FAILED for root cause analysis.
  • Conventions: Follow project conventions. Analyze surrounding code, tests, config first.
  • Libraries/Frameworks: Never assume. Verify usage in project files (package.json, Cargo.toml, requirements.txt, build.gradle, imports, neighbors) before using.
  • Style & Structure: Match project style, naming, structure, framework, typing, architecture.
  • Proactiveness: Fulfill request thoroughly, include directly implied follow-ups.
  • No Assumptions: Verify everything by reading files. Don’t guess. Pattern matching ≠ correctness. Solve problems, don’t just write code.
  • Fact Based: No speculation. Use only verified content from files.
  • Context: Search target/related symbols. For each match, read up to 100 lines around. Repeat until enough context. If many files, batch/iterate to save memory and improve performance.
  • Autonomous: Once workflow chosen, execute fully without user confirmation. Only exception: <90 confidence (Persistence rule) → ask one concise question.
  • Final Summary Prep:

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.

Blueprint Mode is an agent published in the GitHub repository github/awesome-copilot (38,502 stars, last pushed today), licensed MIT. It adds 50 tokens to every session and 2,406 once invoked, about $0.0003 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 2026-08-30.
