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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Excessive Agency · line 12 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
What it costs to keep this loaded
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 | $0.00044 | $0.01030 |
| Opus 5 | $0.00022 | $0.00515 |
| Sonnet 5 | $0.00009 | $0.00206 |
| Haiku 4.5 | $0.00004 | $0.00103 |
Grade A, and why
duolingo-play 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 9d 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 — 90 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Duolingo Play
Use this skill to help users complete Duolingo language lessons efficiently on a mobile device.
Core Principle
Actively help the user complete lessons. Do not ask the user what the answer is — read the screen, determine the correct answer, and execute the action. The user expects you to drive the lesson, not spectate.
Lesson Types & How to Handle
Word Bank / Translation Tasks
- Tap the correct word tiles from the bank to form the translation.
- Prefer batch action: read the full sentence first, plan the complete answer, then tap all words in order — include the Check button as the final tap in the same batch. Do not tap one word, screenshot, tap another — this is slow and error-prone.
- Example: for a 5-word answer, issue a single batch of 6 taps — word1, word2, word3, word4, word5, then the
Checkbutton at the bottom. - If a word tile is wrong or out of order, tap it from the top (the answer area) to remove it, then tap the correct word from the bank.
Matching Pairs
- Tap one item on the left, then its match on the right.
- Work through pairs systematically — matched pairs disappear, so re-screenshot after every 1–2 matches to see remaining items.
Listening Exercises
- Tap the speaker icon to play audio, then type or select the answer.
- If you cannot hear audio, tap "Can't listen now" or the skip button if available.
Speaking Exercises
- These require microphone input the agent cannot provide.
- Tap "Can't speak now" or the skip button to proceed.
Type the Answer (Free Input)
- Tap the text input field to focus it.
- Type the full answer using
type_text, then tap the check button. - Watch for auto-correct or keyboard suggestions interfering — dismiss them if needed.
Select the Correct Image
- Identify the image matching the prompt and tap it.
Fill in the Blank
- Read the sentence context, determine the missing word, and tap the correct option.
Navigation
- Check button: always at the bottom of the screen — tap it after entering/selecting your answer.
- Continue button: appears after checking — tap it to move to the next question. It often appears in the same position as the check button.
- Progress bar: at the top of the screen, shows lesson completion progress.
- Close (X): top-left corner to exit a lesson (will prompt confirmation).
- Heart / lives display: top of screen — if hearts run out, the lesson ends.
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.

duolingo-play is a skill published in the GitHub repository pockebot/openpocket (841 stars, last pushed 2mo ago), licensed MIT. It adds 44 tokens to every session and 1,030 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.
