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 | $0.00054 | $0.03181 |
| Opus 5 | $0.00027 | $0.01590 |
| Sonnet 5 | $0.00011 | $0.00636 |
| Haiku 4.5 | $0.00005 | $0.00318 |
Grade A, and why
pomodoro 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 — 414 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Pomodoro Timer Skill
Overview
A 25-minute timer for focused work sessions that saves every session to SQLite. Enables history tracking, productivity analytics, and pattern recognition over time.
This is a System Skill - it provides handles to operate a personal data system. As commands run and sessions accumulate, context builds and compounds. The system learns patterns and provides increasingly valuable insights through an OODA loop of observation, orientation, decision, and action.
Mental Model: The OODA Loop
Operating this skill involves running a continuous cycle:
- Observe → Check current status (
./pomodoro status) and review history (./pomodoro history) - Orient → Analyze patterns in the data (
./pomodoro stats --period week) - Decide → Determine optimal actions (e.g., "Morning sessions have 95% completion - schedule deep work then")
- Act → Start sessions (
./pomodoro start), provide recommendations, celebrate milestones
Each cycle builds on accumulated data, making insights more valuable over time.

Quick Decision Tree
User task → What kind of request?
├─ Start focused work → Check status first, then start session
├─ Check current timer → Use status command
├─ Review productivity → Use stats command (day/week/month/year)
├─ View past sessions → Use history command
└─ Stop early → Use stop command
Core Commands
To see all available options: Run ./pomodoro --help or ./pomodoro <command> --help
Starting a Session
Begin a Pomodoro session:
# Traditional 25-minute Pomodoro
./pomodoro start --task "Refactor authentication module"
# Custom durations and cycles
./pomodoro start --task "Quick review" --work 5 --break 3 --cycles 2
./pomodoro start --task "Deep focus" --work 50 --break 10 --cycles 1
# Flash cards (rapid cycles)
./pomodoro start --task "Flash cards" --work 2 --break 1 --cycles 5
What ships with it
5 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.

pomodoro is a skill published in the GitHub repository jakedahn/pomodoro (56 stars, last pushed 10mo ago), licensed MIT. It adds 54 tokens to every session and 3,181 once invoked, about $0.0003 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.
