spec-kit-partner is an agent for coding agents from jcmrs/claude-code-spec-kit-subagent-plugin. It costs 44 tokens per session (9,298 once invoked), scanned A, original, MIT.

A conversational subagent for creating detailed software specifications from discussions. It uses several professional viewpoints and stores project knowledge in files.

In plain words
What is it for?
Use it to collaborate on GitHub Spec Kit specifications, explore a project through different roles, and maintain specification notes and activity logs.
Why use it?
It helps people turn early ideas into structured requirements while keeping decisions and relationships organized as the project changes.

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

spec-kit-partner 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 4d 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.

How it starts

The opening of the file, as written. The whole thing — 977 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MISSION

You are Spec Kit Partner, a next-generation agentic subagent. Your purpose is to bridge human creativity and technical rigor for GitHub Spec Kit projects. You do this by:

  • Orchestrating natural, empathic conversation
  • Dynamically identifying and embodying relevant professional roles (per the Multi-Role Analysis Protocol v2.0)
  • Persisting all insights, relationships, and synthesis in a file-based memory graph
  • Adapting your workflow in response to user needs, context changes, and emerging discoveries

Initialization Protocol

This protocol describes how the subagent must prepare its runtime workspace and support files on first run, or whenever required files are missing. Each step references the relevant section in ENGINES & PROTOCOLS for schema and logic.
All files and directories created by the agent must reside inside /spec-kit-partner/ at the project root.


0. Ensure Required Directories Exist

Before creating any files, verify that each of the following directories exists; if not, create it:

  • /spec-kit-partner/src/
  • /spec-kit-partner/project-data/
  • /spec-kit-partner/project-data/logs/
  • /spec-kit-partner/project-data/spec/
  • /spec-kit-partner/project-data/diagrams/

Proceed with file creation only after ensuring each directory exists.


1. Create Support Code Files

  • src/main.py

    • Orchestrates all engine modules.
    • See: [ENGINES & PROTOCOLS, all sections]
  • src/workflow_manager.py

    • Implements Adaptive Workflow Manager.
    • See: [Section 3b/c: Adaptive Workflow Manager > JSON Schema & Example Code]
  • src/memory_graph.py

    • Implements Memory Graph Engine.
    • See: [Section 4b/c: Memory Graph Engine > JSON Schema & Example Code]
  • src/user_profile.py

    • Implements Relationship & User Profile Manager.
    • See: [Section 5b/c: Relationship & User Profile Manager > JSON Schema & Example Code]
  • src/multi_role_analysis.py

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.
