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 | $0.00000 | $0.01083 |
| Opus 5 | $0.00000 | $0.00541 |
| Sonnet 5 | $0.00000 | $0.00217 |
| Haiku 4.5 | $0.00000 | $0.00108 |
Grade A, and why
check-cross-layer 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 6d 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.

Cross-Layer Check
Check if your changes considered all dimensions. Most bugs come from "didn't think of it", not lack of technical skill.
Note: This is a post-implementation safety net. Ideally, read the Pre-Implementation Checklist before writing code.

Execution Steps
1. Identify Change Scope
git status
git diff --name-only
2. Select Applicable Check Dimensions
Based on your change type, execute relevant checks below:
Dimension A: Cross-Layer Data Flow (Required when 3+ layers)
Trigger: Changes involve 3 or more layers
| Layer | Common Locations |
|---|---|
| API/Routes | routes/, api/, handlers/, controllers/ |
| Service/Business Logic | services/, lib/, core/, domain/ |
| Database/Storage | db/, models/, repositories/, schema/ |
| UI/Presentation | components/, views/, templates/, pages/ |
| Utility | utils/, helpers/, common/ |
Checklist:
- Read flow: Database -> Service -> API -> UI
- Write flow: UI -> API -> Service -> Database
- Types/schemas correctly passed between layers?
- Errors properly propagated to caller?
- Loading/pending states handled at each layer?
Detailed Guide: .trellis/spec/guides/cross-layer-thinking-guide.md
Dimension B: Code Reuse (Required when modifying constants/config)
Trigger:
- Modifying UI constants (label, icon, color)
- Modifying any hardcoded value
- Seeing similar code in multiple places
- Creating a new utility/helper function
- Just finished batch modifications across files
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.

check-cross-layer is a command published in the GitHub repository mistydew/tokenicode-deepseek-alpha (367 stars, last pushed 1mo ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,083 tokens. 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.

checklist
Generate a custom checklist for the current feature based on user requirements.
clarify
Identify underspecified areas in the current feature spec by asking up to 5 highly targeted clarification questions and encoding answers back into the spec.
specify
Create or update the feature specification from a natural language feature description.
analyze
Perform a non-destructive cross-artifact consistency and quality analysis across spec.md, plan.md, and tasks.md after task generation.
constitution
Create or update the project constitution from interactive or provided principle inputs.
converge
Assess the current codebase against the feature's spec, plan, and tasks, then append any remaining unbuilt work as new tasks to tasks.md so implement can complete it.
