.github/copilot-instructions.md

JumpStart-AutoNav copilot-instructions.md is an instructions file for GitHub Copilot from CGSOG-JumpStarts/JumpStart-AutoNav. It costs 1,357 tokens per session, scanned A, original, MIT.

Repository-specific instructions for the JumpStart-AutoNav project, which uses a specification-first workflow with several specialized development phases.

In plain words
What is it for?
Use them when planning, analyzing, documenting, or implementing changes in that repository, especially when using an external library, command-line tool, framework, or service.
Why use it?
They tell coding agents where the project’s product, architecture, style, dependency, and feature specifications live, and require verified documentation for external technologies.

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

JumpStart-AutoNav 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 10d 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.

Jump Start Framework

This project uses the Jump Start spec-driven agentic coding framework. Development follows five sequential phases, each owned by a specialized AI agent.

Context7 MCP Mandate (HIGH PRIORITY)

CRITICAL RULE: When referencing any external library, framework, CLI tool, or service — you MUST use Context7 MCP to fetch live, verified documentation. Never rely on training data for API signatures, configuration flags, version compatibility, or setup instructions.

How to use Context7:

  1. Resolve the library ID: Use mcp_context7_resolve-library-id with libraryName and query parameters
  2. Fetch current docs: Use mcp_context7_query-docs with libraryId (e.g., /vercel/next.js) and query parameters
  3. Add [Context7: library@version] citation marker in output

Full documentation: .jumpstart/guides/context7-usage.md

When required: Architect Phase 3 (Documentation Freshness Audit — hard gate, ≥80% score), Developer Phase 4 (before writing external API integration code), Analyst Phase 1 (technology evaluation), any agent making technology claims.

Spec-First Power Inversion

Specs are the source of truth. Code is derived. If there is a mismatch between a spec artifact and the codebase, update the spec first or regenerate the code. Never silently alter code to diverge from specs.

Workflow

[Brownfield only] Pre-Phase (Scout) -> Phase 0 (Challenger) -> Phase 1 (Analyst) -> Phase 2 (PM) -> Phase 3 (Architect) -> Phase 4 (Developer)

Pit Crew (/jumpstart.pitcrew) can be invoked at any phase for multi-agent advisory discussions via the Facilitator agent.

Phases are strictly sequential. Each must be completed and approved by the human before the next begins. For brownfield projects (project.type: brownfield in config), the Scout agent runs before Phase 0 to analyze the existing codebase.

Key Directories

  • .jumpstart/agents/ -- Detailed agent personas with step-by-step protocols (includes scout.md for brownfield)
  • .jumpstart/templates/ -- Artifact templates that structure each phase's output (includes codebase-context.md, agents-md.md)
  • .jumpstart/schemas/ -- JSON Schema (draft-07) definitions for artifact validation
  • .jumpstart/config.yaml -- Framework settings (agent parameters, workflow rules, project type)
  • .jumpstart/roadmap.md -- Project Roadmap: non-negotiable principles that govern all agents
  • .jumpstart/roadmap.md -- Engineering articles governing code quality and architecture decisions
  • .jumpstart/invariants.md -- Environment invariants that must hold true in every deployment
  • .jumpstart/domain-complexity.csv -- Domain complexity data for adaptive planning rigor
  • .jumpstart/glossary.md -- Terminology dictionary: canonical term definitions for consistent naming
  • .jumpstart/correction-log.md -- Self-correction log: rejected proposals and lessons learned
  • .jumpstart/state/ -- Workflow state persistence (state.json, todos.json, adr-index.json, locks/)
  • .jumpstart/archive/ -- Timestamped archives of overwritten artifacts
  • specs/ -- Generated specification artifacts (the source of truth for this project)
  • specs/codebase-context.md -- Scout output for brownfield projects (existing codebase analysis with C4 diagrams)
  • specs/decisions/ -- Architecture Decision Records
  • specs/insights/ -- Living insight logs (1:1 with each artifact)
  • specs/qa-log.md -- Q&A decision log: audit trail of every agent question and human response
  • specs/research/ -- Optional research artifacts (competitive analysis, technical spikes)

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.
