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 | $0.00050 | $0.01888 |
| Opus 5.5 | $0.00020 | $0.00755 |
| Sonnet 5.5 | $0.00010 | $0.00378 |
| Haiku 4.5 | $0.00005 | $0.00189 |
Grade A, and why
notion-spec-to-implementation 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.
This is a copy
100% identical to notion-spec-to-implementation — 271 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.
How it starts
The opening of the file, as written. The whole thing — 220 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Spec to Implementation
Transforms specifications into actionable implementation plans with progress tracking. Fetches spec documents, extracts requirements, breaks down into tasks, and manages implementation workflow.
Quick Start
When asked to implement a specification:
- Find spec: Use
Notion:notion-searchto locate specification page - Fetch spec: Use
Notion:notion-fetchto read specification content - Extract requirements: Parse and structure requirements from spec
- Create plan: Use
Notion:notion-create-pagesfor implementation plan - Find task database: Use
Notion:notion-searchto locate tasks database - Create tasks: Use
Notion:notion-create-pagesfor individual tasks in task database - Track progress: Use
Notion:notion-update-pageto log progress and update status
Implementation Workflow
Step 1: Find the specification
1. Search for spec:
- Use Notion:notion-search with spec name or topic
- Apply filters if needed (e.g., created_date_range, teamspace_id)
- Look for spec title or keyword matches
- If not found or ambiguous, ask user for spec URL/ID
Example searches:
- "User Authentication spec"
- "Payment Integration specification"
- "Mobile App Redesign PRD"
Step 2: Fetch and analyze specification
1. Fetch spec page:
- Use Notion:notion-fetch with spec URL/ID from search results
- Read full content including requirements, design, constraints
2. Parse specification:
- Identify functional requirements
- Note non-functional requirements (performance, security, etc.)
- Extract acceptance criteria
- Identify dependencies and blockers
See reference/spec-parsing.md for parsing patterns.
Step 3: Create implementation plan
1. Break down into phases/milestones
2. Identify technical approach
3. List required tasks
4. Estimate effort
5. Identify risks
Use implementation plan template (see [reference/standard-implementation-plan.md](reference/standard-implementation-plan.md) or [reference/quick-implementation-plan.md](reference/quick-implementation-plan.md))

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.

notion-spec-to-implementation is a skill published in the GitHub repository MSApps-Mobile/claude-plugins (9 stars, last pushed yesterday), licensed MIT. It adds 50 tokens to every session and 1,888 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. It is 100% identical to notion-spec-to-implementation, differing in 271 lines, and is treated as a copy.
