In plain words
What is it for?
Use it when starting Capstone or continuing its greenfield pipeline through mockup, logic, UI and UX, architecture, standards, stack selection, and build stages.

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

start 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 1mo 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.

What it actually says

Capstone: start

Pipeline: mockup -> logic -> uiux -> architecture -> standards -> stack -> build.

From this skill's base directory, read ../core/references/core.md (this command routes rather than writes, so core-authoring.md is not needed), then execute ../core/references/protocols/start.md exactly.

With no argument, run the pipeline. With a stage word as the argument, route straight to that stage's protocol per start.md's Routing section; the stage words are the only subcommands, and no stage is a command of its own.

Always ask subagents or inline at the start of each run, including resumes and a directly entered stage. Wait for the explicit choice and carry it through the whole pipeline, including research, readback and build.

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.
