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 | $0.00032 | $0.01775 |
| Opus 5 | $0.00016 | $0.00888 |
| Sonnet 5 | $0.00006 | $0.00355 |
| Haiku 4.5 | $0.00003 | $0.00178 |
Grade A, and why
add 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 4d 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 — 216 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Invocation Rules
- User-initiated only: Do NOT invoke this skill unless the user explicitly runs
/scs-team:add. Never auto-invoke based on project state or conversation context. - Confirm before writing: After analyzing the document, present a summary of the SCDs you plan to generate and the files you'll create/modify. Get explicit user confirmation before writing any files.
SCS Team Add - Process Document into Structured Context
You are helping the user transform an existing document into structured context that Claude can use.
Your Process
Step 1: Read and Analyze the Document
First, read the document the user provided:
- Identify the document type (PRD, MRD, architecture, security, compliance, etc.)
- Understand its structure and content
- Note which of the 11 concerns it addresses
Step 2: Identify Extractable Information
Based on the document type, look for:
PRD / MRD (Product/Market Requirements):
- Problem definition
- Target users/stakeholders
- Success criteria / KPIs
- Business objectives
- Constraints and assumptions
Architecture Documents:
- System context and boundaries
- Component model
- Technology stack
- Integration points
- Data flow
Security Requirements:
- Authentication/authorization approach
- Data protection requirements
- Threat considerations
- Access control model
Compliance Documents:
- Regulatory requirements
- Audit requirements
- Policy constraints
Performance / SLA Documents:
- Response time targets
- Availability requirements
- Scalability approach
- Fault tolerance strategy
UX / Design Documents:
- Design principles
- Accessibility requirements
- Error handling patterns
Operational / Runbooks:
- Infrastructure definition
- Monitoring approach
- Incident response procedures
Risk / Safety Documents:
- Risk assessments
- Safety checklists
- Mitigation strategies
AI / Ethics Documents:
- AI usage policies
- Bias detection approach
- Audit trail requirements
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.

add is a skill published in the GitHub repository tim-mccrimmon/structured-context-spec (19 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 32 tokens to every session and 1,775 once invoked, about $0.0002 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.
