Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00013 | $0.00515 |
| Opus 5.5 | $0.00005 | $0.00206 |
| Sonnet 5.5 | $0.00003 | $0.00103 |
| Haiku 4.5 | $0.00001 | $0.00052 |
Grade A, and why
gsd-new-milestone 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 27d 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
Brownfield equivalent of new-project. Project exists, PROJECT.md has history. Gathers "what's next", updates PROJECT.md, then runs requirements → roadmap cycle.
Creates/Updates:
.planning/PROJECT.md— updated with new milestone goals.planning/research/— domain research (optional, NEW features only).planning/REQUIREMENTS.md— scoped requirements for this milestone.planning/ROADMAP.md— phase structure (continues numbering).planning/STATE.md— reset for new milestone
After: /gsd-plan-phase [N] to start execution.

Project and milestone context files are resolved inside the workflow (init new-milestone) and delegated via <files_to_read> blocks where subagents are used.
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.
