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.
npx agentmods add instructions/rhyanvargas/agentic-development-starter-kit/agents-mdgit clone --depth 1 https://github.com/rhyanvargas/agentic-development-starter-kitWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.01390 | $0.01390 |
| Opus 5 | $0.00695 | $0.00695 |
| Sonnet 5 | $0.00278 | $0.00278 |
| Haiku 4.5 | $0.00139 | $0.00139 |
Grade A, and why
agentic-development-starter-kit AGENTS.md 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 2d 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.
How it starts
The opening of the file, as written. The whole thing — 79 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Instructions — The Agentic Development Starter Kit (ADSK)
This repository is the kit source (package + optional Cursor wiring).
Adopters adding ADSK to an app: follow docs/using-adsk.md — install into .agents/skills/, not a root skills/ folder. Org rules/policies (survive kit updates): docs/customizing-org-rules.md.
Product direction (adopter)
- Contract: docs/product/create-adsk.md — kit profile adoption, not a skills marketplace.
- Profiles:
profiles.json(core / delivery / maintainer / skills-only). - Rule:
.cursor/rules/adopter-product/— do not invent skill-picker UX that competes with skills.sh. - Adopter CLI:
npx create-adsk(packages/create-adsk) — wrapsnpx skills+ Cursor adopter sync; living spec.cursor/docs/specs/create-adsk.md. - Alternate:
npx skills add …and/orscripts/sync-adsk.sh adopter --from <kit>(see using-adsk).
When the user asks to sync ADSK
Do not hand-copy skill trees or Cursor files.
| Context | Run |
|---|---|
| This kit repo | ./scripts/sync-adsk.sh kit (optional: ./scripts/sync-adsk.sh self-check) |
Adopter app with .adsk/config.json |
npx create-adsk update (or status) |
| Adopter app (script path) | Resolve kit checkout → <kit>/scripts/sync-adsk.sh adopter --from <kit> from the app root |
Playbook: .cursor/commands/sync-adsk.md. Dual-audience steps: docs/upgrading.md.
Kit layout (this repo)
- Package source:
skills/<name>/(Agent SkillsSKILL.md— whatnpx skills addships) - Discovery links (do not duplicate trees):
.agents/skills/<name>→../../skills/<name>.cursor/skills/<name>→../../skills/<name>
- Cursor wiring:
.cursor/commands/,.cursor/rules/— thin wrappers; reference skills, don’t copy playbooks - Sync script:
scripts/sync-adsk.sh
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.
