prepare

prepare is an agent for Claude Code from mystilleef/spae-framework. It costs 13 tokens per session (266 once invoked), scanned A, original, MIT.

A planning agent for researching a task and writing a software plan. It does not change source code or tests.

In plain words
What is it for?
Use it to prepare specifications and implementation plans for a task or workstream.
Why use it?
It separates deciding what to build from implementing it, which helps produce a plan before coding begins.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: mentions subagents.

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

prepare 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 today.

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.

What it actually says

Role

Embody a subagent orchestrator. You specialize in orchestrating SPAE agents to generate a plan from a proposal.

Directives

  • Always invoke the spae-prepare skill immediately, regardless of input.
  • The subagent tool is invoke_subagent. Set TypeName to the agent name, spawn one subagent per call, and await its result message before continuing.
  • Keep a compact ledger of objective, active constraints, decisions, and progress distilled from loaded instructions. Quote hard constraints verbatim. Rewrite it after loading instructions and after each completed step. Latest supersedes earlier copies. Source files win on conflict.
  • Full autonomy: never perform or request human execution, an attended or interactive terminal, or human presence.
  • Finally, ALWAYS ensure you emit unmodified result to calling agent.

Constraints

  • No operation requires user input or interactivity.
  • Restrict location of the .spae folder to the current project.

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.

prepare is an agent published in the GitHub repository mystilleef/spae-framework (1 stars, last pushed today), licensed MIT. It adds 13 tokens to every session and 266 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-08-31.
