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 | $0.00017 | $0.00938 |
| Opus 5.5 | $0.00007 | $0.00375 |
| Sonnet 5.5 | $0.00003 | $0.00188 |
| Haiku 4.5 | $0.00002 | $0.00094 |
Grade A, and why
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.

Overview
The Spec-to-Implementation skill transforms project specifications into detailed implementation plans with comprehensive task breakdowns, timeline estimates, and dependency tracking in Notion. It bridges the gap between requirements and execution.
When to Use
Use this skill when you need to:
- Convert project specifications into actionable implementation plans
- Break down complex features into implementable tasks
- Create detailed project timelines with estimates
- Identify dependencies and critical path items
- Generate task checklists with ownership and deadlines
- Track implementation progress in Notion
- Create architectural and technical specifications from requirements
Features
- Smart Requirement Parsing: Automatically extracts requirements and acceptance criteria
- Task Decomposition: Breaks specifications into atomic, implementable tasks
- Dependency Mapping: Identifies and visualizes task dependencies
- Effort Estimation: Provides time estimates for tasks and milestones
- Ownership Assignment: Creates task assignments with clarity
- Progress Tracking: Sets up Notion databases for implementation tracking
- Risk Identification: Highlights potential implementation risks and blockers
Requirements
- Notion API Access: For creating implementation plans and task databases
- Specification Format: Clear specification documents (markdown, PDFs, or text)
- Team Database: Directory of team members and skills (optional but recommended)
- Project Template: Pre-configured Notion template for consistency
Implementation Details
This skill transforms specifications through a systematic process:
- Parse specification document and extract requirements
- Break requirements into user stories and tasks
- Identify technical dependencies and blockers
- Create detailed implementation plan with phases
- Estimate effort for each task
- Assign ownership and set deadlines
- Create tracking structure in Notion
- Generate project dashboard and status reports
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.

spec-to-implementation is a skill published in the GitHub repository tommy-ca/notion-skills (69 stars, last pushed 11mo ago), licensed MIT. It adds 17 tokens to every session and 938 once invoked, about $0.0001 per session on Opus 5.5. 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.

Records research provenance as a post-task epilogue, scanning conversation history at the end of a coding or research session to extract decisions, experiments, dead ends, claims, heuristics, and pivots, and writing them into the ara/ directory with user-vs-AI provenance tags. Use as a session epilogue — never during…

Use when projects or tasks need explicit state, WIP control, ownership, definitions of done, blocker handling, and verified closure.
