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 | $0.00044 | $0.00547 |
| Opus 5.5 | $0.00018 | $0.00219 |
| Sonnet 5.5 | $0.00009 | $0.00109 |
| Haiku 4.5 | $0.00004 | $0.00055 |
Grade A, and why
fullstack-dev 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.

Fullstack Dev
This skill is a compact execution guide for API-backed feature work.
When To Use
Use this skill when the current subtask requires both sides of the system:
- adding or updating an API endpoint and the UI that consumes it
- implementing authentication, authorization, or session-dependent features
- shipping CRUD flows that span schema, handlers, client calls, and UI states
- wiring file upload, background processing, or realtime updates into the product
Core Rules
- Read the existing code paths end to end before editing.
- Keep the scope anchored to the current subtask; do not expand into a full rewrite.
- Prefer existing architectural patterns over introducing a second style.
- Make backend and frontend contracts explicit in code, not implied in prose.
- If a migration, config change, or dependency is required, apply the minimal robust change.
Backend Standards
- Validate input at the boundary.
- Return consistent success and error shapes.
- Do not hide failures with overly broad catch blocks.
- Keep business logic out of transport-layer glue where the project already separates them.
- Preserve auth and permission checks on every protected path.
Frontend Standards
- Reflect backend validation and auth states in the UI.
- Handle loading, empty, success, and error states explicitly.
- Do not assume stale cached data is correct after a write; refresh or reconcile it.
- Keep form state, optimistic updates, and retries understandable and bounded.
Integration Checklist
- Confirm route or handler registration.
- Confirm request payload and response shape.
- Confirm the client call site and state update path.
- Confirm in-scope permission behavior.
- Confirm not-found, invalid-input, and duplicate/conflict behavior where relevant.
Review Bar
The subtask is only ready for review when:
- the feature works across the backend/frontend boundary
- validation and error handling are present on both sides where needed
- auth and access control remain correct
- the implementation is integrated into the actual user flow, not left orphaned
- touched files are limited to what the subtask really needs
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.

fullstack-dev is a skill published in the GitHub repository qinghaoliqaq/AutoCoder (12 stars, last pushed 5mo ago), licensed Apache-2.0. It adds 44 tokens to every session and 547 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.
