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 | $0.00007 | $0.04015 |
| Opus 5 | $0.00003 | $0.02008 |
| Sonnet 5 | $0.00001 | $0.00803 |
| Haiku 4.5 | $0.00001 | $0.00402 |
Grade A, and why
spec-design 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 2d 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 — 459 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Technical Design
Generate a technical design document for feature $1.
Task: Create Technical Design Document
1. Prerequisites & File Handling
- Requirements Approval Check:
- If invoked with
-y($2 == "-y"), setrequirements.approved=trueinspec.json - Otherwise, stop with an actionable message if requirements are missing or unapproved
- If invoked with
- Design File Handling:
- If design.md does not exist: Create new design.md file
- If design.md exists: Interactive prompt with options:
- [o] Overwrite: Generate completely new design document
- [m] Merge: Generate new design document using existing content as reference context
- [c] Cancel: Stop execution for manual review
- Context Loading: Read
.kiro/specs/$1/requirements.md, core steering documents, and existing design.md (if merge mode)
2. Discovery & Analysis Phase
CRITICAL: Before generating the design, conduct thorough research and analysis:
Feature Classification & Process Adaptation
Classify feature type to adapt process scope:
- New Feature (greenfield): Full process including technology selection and architecture decisions
- Extension (existing system): Focus on integration analysis, minimal architectural changes
- Simple Addition (CRUD, UI): Streamlined process, follow established patterns
- Complex Integration (external systems, new domains): Comprehensive analysis and risk assessment
Process Adaptation: Skip or streamline analysis steps based on classification above
A. Requirements to Technical Components Mapping
- Map requirements (EARS format) to technical components
- Extract non-functional requirements (performance, security, scalability)
- Identify core technical challenges and constraints
B. Existing Implementation Analysis
MANDATORY when modifying or extending existing features:
- Analyze codebase structure, dependencies, patterns
- Map reusable modules, services, utilities
- Understand domain boundaries, layers, data flow
- Determine extension vs. refactor vs. wrap approach
- Prioritize minimal changes and file reuse
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.

spec-design is a command published in the GitHub repository kbwo/ccmanager (1,229 stars, last pushed 2d ago), licensed MIT. It adds 7 tokens to every session and 4,015 once invoked, about $0.0000 per session on Opus 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.
