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

gsd-new-project 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 8d 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.

gsd-new-project

Initialize a new project with GSD (Get Stuff Done) planning artifacts.

When to Use

  • User says "new project", "新项目", "init project", "start project"
  • User wants to bootstrap a structured project workspace

Workflow

Step 1: Gather Project Idea

Ask the user: "What is your project idea?" (or accept from command arguments).

Step 2: Check for Existing Planning Directory

Use exec to check if memory/.planning/ already exists.

ls -la memory/.planning/ 2>/dev/null

If it exists, warn the user: "memory/.planning/ already exists. Continuing will overwrite existing planning files. Proceed? (yes/no)"

If the user declines, stop here.

Step 3: Create Planning Artifacts

Use the write tool to create each file.

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
