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 | $0.00084 | $0.00507 |
| Opus 5.5 | $0.00034 | $0.00203 |
| Sonnet 5.5 | $0.00017 | $0.00101 |
| Haiku 4.5 | $0.00008 | $0.00051 |
Grade A, and why
kiro-guide 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.
How it starts
The opening of the file, as written. The whole thing — 36 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Kiro Hooks
Configure Kiro's native hook and action surface without inventing unsupported guarantees or a universal hook file.
Essentials
- Pin schema and surface - Record v1 hook schema, IDE/CLI surface, documentation snapshot, and observed runtime.
- Prefer command actions - Use deterministic commands for policy, formatting, validation, and audit.
- Bound agent actions - Treat Ask Kiro actions as model execution with credits, authority, and output limits.
- Use exit code 2 precisely - Blocking applies only to documented pre-events.
- Respect workspace roots - File events and configuration are scoped to the defining workspace root.
- Review generated hooks - Natural-language generation is a draft requiring diff, security review, tests, and authorization.
Gotchas
- Command exit code
2blocks onlyPreToolUse,UserPromptSubmit, andPreTaskExecin the v1 reference. - Other non-zero exits warn and normally continue.
- Agent actions start another agent loop and consume credits; they are not deterministic commands.
- Setting timeout
0disables the command timeout and violates bounded-module defaults. - Generated hook configurations must be reviewed before saving or sharing.
Example
A pre-tool protected-path hook uses a v1 workspace JSON file and a bounded command action; its preview includes the matcher, exit-2 denial, command timeout, workspace trust, stdout/stderr exposure, enable flag, test cases, and removal rollback.
Progressive Disclosure
- Read references/capabilities.md - Load when mapping semantic intents to native events, handlers, guarantees, versions, ordering, context, or limitations
- Read references/onboarding.md - Load when discovering, previewing, applying, verifying, disabling, rolling back, updating, or detecting drift
- Read references/patterns.md - Load when translating deterministic hooks, model evaluators, specialist agents, or managed adoption recipes
What ships with it
7 files 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.

kiro-guide is a skill published in the GitHub repository xonovex/platform (6 stars, last pushed 2d ago), licensed MIT. It adds 84 tokens to every session and 507 once invoked, about $0.0003 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 2026-09-08.
