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 | $0.00045 | $0.03491 |
| Opus 5 | $0.00023 | $0.01746 |
| Sonnet 5 | $0.00009 | $0.00698 |
| Haiku 4.5 | $0.00005 | $0.00349 |
Grade A, and why
Focus Session Manager 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 8d 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.

Focus Session Manager
Protect your health. Maximize focus. Prevent burnout.
Core Principle
ADHD brains are prone to hyperfocus (ignoring breaks, health) and time blindness (losing track of time). The solution: Automated session management that tracks time, enforces breaks, and protects health without disrupting flow state.
Key Insight: You can't manage time you can't see. Make time visible and automatic.
The Focus Problem
Problem 1: Hyperfocus Burnout
Issue: Code for 4 hours straight without break Result: Exhaustion, health issues, reduced quality
Problem 2: Time Blindness
Issue: "I'll work for 30 min" → Actually 3 hours Result: Missed meetings, forgotten commitments, burnout
Problem 3: Break Resistance
Issue: "Just one more thing" never stops Result: No breaks, deteriorating health, reduced productivity
Problem 4: Disrupted Flow
Issue: Harsh timer interruptions break concentration Result: Frustration, ignoring timers, no break system
Phase 1: Automatic Session Tracking
Always-On Time Tracking
Starts automatically when you begin coding:
[Session Started: 14:00]
⏱️ Focus Timer Running
📊 Today's focus time: 0 hours
🎯 Goal: 4 hours
🔥 Current streak: 2 days
Mode: Deep Work
Next break: 14:25 (in 25 min)
Visible Time Display
Status bar shows:
⏱️ 23:45 | 🧠 Focus Session 1/4 | 💧 Water reminder soon
Session Types (Auto-Detected)
Deep Work: Complex coding, architecture
- Duration: 45-90 minutes
- Break: 15 minutes
- Best for: New features, debugging
Quick Tasks: Bug fixes, updates
- Duration: 25 minutes
- Break: 5 minutes
- Best for: Small fixes, reviews
Learning: Reading docs, tutorials
- Duration: 30 minutes
- Break: 10 minutes
- Best for: New tech, research
Phase 2: ADHD-Optimized Pomodoro
Traditional Pomodoro (ADHD-Hostile)
❌ Rigid 25-min timer (might be mid-thought) ❌ Harsh interruption (breaks flow) ❌ Forced break (when you're in flow) ❌ No hyperfocus protection (ignores long sessions)
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.

Focus Session Manager is a skill published in the GitHub repository daffy0208/ai-dev-standards (36 stars, last pushed 8mo ago), licensed MIT. It adds 45 tokens to every session and 3,491 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.
