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 | $0.00034 | $0.00380 |
| Opus 5 | $0.00017 | $0.00190 |
| Sonnet 5 | $0.00007 | $0.00076 |
| Haiku 4.5 | $0.00003 | $0.00038 |
Grade A, and why
select-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 yesterday.
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
Select Project Skill
Quick project switching within a configured monorepo.
Workflow
Step 1: Load Config
Read .groundwork.yml from the repo root.
If not found: "No .groundwork.yml found. Run /groundwork:setup-repo to configure your repository first."
Step 2: List Projects
Present available projects with their spec status:
## Available Projects
| # | Project | Path | Specs |
|---|---------|------|-------|
| 1 | web-app | apps/web-app | PRD, Architecture, Tasks |
| 2 | mobile-app | apps/mobile-app | PRD |
| 3 | api-server | services/api | (none) |
For each project, check if <path>/specs/ exists and what spec files are present.
Use AskUserQuestion to ask which project to work on.
Step 3: Set Context
Persist the selection and use the returned project/root values as the active context:
node ${CLAUDE_PLUGIN_ROOT}/lib/persist-project.js "<selected-name>"
The script resolves its own harness-specific selection scope internally — no env vars required.
Confirm: "Switched to project . Specs at <path>/specs/."
Step 4: Show Status
After switching, show the project's spec status:
- PRD: exists / missing
- Architecture: exists / missing
- Tasks: exists / missing
- Design System: exists / missing
Suggest next action based on what's available.
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.

select-project is a skill published in the GitHub repository etr/groundwork (42 stars, last pushed 20d ago), licensed MIT. It adds 34 tokens to every session and 380 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
