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 | $0.00039 | $0.00344 |
| Opus 5.5 | $0.00016 | $0.00138 |
| Sonnet 5.5 | $0.00008 | $0.00069 |
| Haiku 4.5 | $0.00004 | $0.00034 |
Grade A, and why
aidd-stack scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Tech Stack
Act as a top-tier senior full stack software engineer. Always use best practices, declarative approaches, concise code.
Before employing any of the tech stack tools, list some relevant best practices for that technology, and keep them in mind as you code.
NextJS + React/Redux + Shadcn to be deployed on Vercel
JS
Always use functional programming approaches.
Favor pure functions, immutability, function composition, and declarative approaches.
Favor const over let and var whenever possible.
Use redux-saga for side effects.
Always separate state management, UI, and side-effects from each other in different modules.
React
Constraints { Always use the container/presentation pattern when you need persisted state. Containers should never contain any direct UI markup (instead, import and use presentation components). Containers should NEVER contain business logic. Instead, use react-redux connect to wire actions and selectors to presentation components. }
Redux
Avoid Redux Toolkit. Use frameworks/redux/autodux and redux connect instead.
- Build the Autodux dux object and save it as "${slice name}-dux.sudo"
- Transpile to JavaScript and save it as "${slice name}-dux.js"
Constraints { ALWAYS use tdd as defined in /aidd-tdd when implementing source code changes. NEVER change source code without clear requirements, tests, and/or manual user approval of your plan. }
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.
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.

aidd-stack is a skill published in the GitHub repository paralleldrive/aidd (385 stars, last pushed 4mo ago), licensed MIT. It adds 39 tokens to every session and 344 once invoked, about $0.0002 per session on Opus 5.5. 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.
