Kiro Crew is a persistent development workspace where agents continue multi-step software work across sessions, schedules, and connected interfaces. Developers use it locally or remotely through a desktop app, web dashboard, CLI, Slack, or Discord, with unattended tasks and recurring jobs. The catalogue contains skills and instructions for working with this workspace.
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 | $0.00078 | $0.01775 |
| Opus 5 | $0.00039 | $0.00888 |
| Sonnet 5 | $0.00016 | $0.00355 |
| Haiku 4.5 | $0.00008 | $0.00178 |
Grade B, and why
ios-simulator-preview scanned grade B with 2 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 5d 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.

A mod that escalates privileges can change anything on the machine, not only the project.

The opening of the file, as written. The whole thing — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
iOS Simulator Preview (Browser-tab mirror)
Mirror a running iOS Simulator into KiroCrew's Browser side panel so the user watches the app — and you driving it — live next to the chat.
Architecture, end to end, all local: simulator → serve-sim (loopback HTTP)
→ the kirocrew:preview marker → Browser panel iframe. Nothing leaves the
machine. This mirrors OpenAI Codex's ios-simulator-browser approach (same
serve-sim mirror) with one substitution: Codex opens the URL in its in-app
browser via a browser tool, while KiroCrew's panel is driven by the hidden
preview marker (see the web-preview skill).
Requirements
- macOS only. Apple's simulator runs nowhere else. On Linux/Windows say so and stop — do not attempt a fallback.
- Xcode with an iOS platform installed, and the license accepted.
xcrun simctl list devicesmust work. - Node/
npx. The launcher pins--registry=https://registry.npmjs.orgbecause a local npm config may default to an authenticated internal registry (which 401s on a public package). Theserve-simversion is pinned in the launcher (SERVE_SIM_VERSION) rather than floated, so a start never auto-executes an unreviewed release; bumping it is a deliberate change. - First
starttakes a couple of minutes (npx download + device boot); later starts are fast.
Resolve the launcher path once
SKILL_DIR="${KIROCREW_HOME:-$HOME/.kiro/crew}/skills/ios-simulator-preview"
Call the script by path; do not cd into the skill folder.
KIROCREW_HOME, when set, must be an ABSOLUTE path (~ is fine — the launcher
expands it). The launcher is invoked by path from whatever directory the session
is in, so a relative home would resolve differently per caller and a start
from one project directory would not be visible to a stop from another. The
launcher refuses a relative value with a JSON error rather than splitting state.
Workflow
1. Start the mirror
python3 "$SKILL_DIR/scripts/sim_mirror.py" start
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.

ios-simulator-preview is a skill published in the GitHub repository kirodotdev/KiroCrew (3,532 stars, last pushed 3d ago), licensed Apache-2.0. It adds 78 tokens to every session and 1,775 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it B with 2 findings (asks for root, runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
