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 | $0.00014 | $0.01078 |
| Opus 5.5 | $0.00006 | $0.00431 |
| Sonnet 5.5 | $0.00003 | $0.00216 |
| Haiku 4.5 | $0.00001 | $0.00108 |
Grade A, and why
kiro-steering-custom 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 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.
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.
This is a copy
94% identical to kiro-steering-custom — 12 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Kiro Custom Steering Creation
<background_information> Role: Create specialized steering documents beyond core files (product, tech, structure).
Mission: Help users create domain-specific project memory for specialized areas.
Success Criteria:
- Custom steering captures specialized patterns
- Follows same granularity principles as core steering
- Provides clear value for specific domain </background_information>
If steering context is already available from conversation, skip redundant file reads. Otherwise:
- Check
.kiro/settings/templates/steering-custom/for available templates - Read
rules/steering-principles.mdfrom this skill's directory for steering principles
Workflow
-
Ask user for custom steering needs:
- Domain/topic (e.g., "API standards", "testing approach")
- Specific requirements or patterns to document
-
Check if template exists:
- Load from
.kiro/settings/templates/steering-custom/{name}.mdif available - Use as starting point, customize based on project
- Load from
-
Analyze codebase (JIT) for relevant patterns:
Parallel Research
The following research areas are independent and can be executed in parallel:
- Template & principles: Load matching template and steering-principles.md
- Domain patterns: Analyze codebase for domain-specific patterns using Glob/Grep/Read
If multi-agent is enabled, spawn sub-agents for each area above. Otherwise execute sequentially.
After all parallel research completes, synthesize findings for steering document.
-
Generate custom steering:
- Follow template structure if available
- Apply principles from
rules/steering-principles.mdfrom this skill's directory - Focus on patterns, not exhaustive lists
- Keep to 100-200 lines (2-3 minute read)
-
Create file in
.kiro/steering/{name}.md
Available Templates
Templates available in .kiro/settings/templates/steering-custom/:
- api-standards.md - REST/GraphQL conventions, error handling
- testing.md - Test organization, mocking, coverage
- security.md - Auth patterns, input validation, secrets
- database.md - Schema design, migrations, query patterns
- error-handling.md - Error types, logging, retry strategies
- authentication.md - Auth flows, permissions, session management
- deployment.md - CI/CD, environments, rollback procedures
What ships with it
2 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-steering-custom is a skill published in the GitHub repository akaghef/M3E (11 stars, last pushed 5d ago), licensed MIT. It adds 14 tokens to every session and 1,078 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 94% identical to kiro-steering-custom, differing in 12 lines, and is treated as a copy.
