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 | $0.00089 | $0.00597 |
| Opus 5 | $0.00044 | $0.00298 |
| Sonnet 5 | $0.00018 | $0.00119 |
| Haiku 4.5 | $0.00009 | $0.00060 |
Grade A, and why
at-home-practice-feedback 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 11d 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 — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.
At-Home Practice Feedback Recommendation
Purpose
Reduce feedback loop time for home drills by recommending practices with
built-in validation and visual reference. The output is a single drill card
the golfer reads on their phone between reps — not a full routine (for a daily
multi-drill routine, use golf-practice-at-home).
Input
- Fault identified (from Trackman data or coach observation — prefer real data:
synthesize(), the currenttraining_plan(action="next")diagnosis, or a quicktrackman-stats-analysisread; never invent a fault) - Root cause (mechanical issue)
- Golfer's available equipment/budget
Sources (don't drift)
- Pull the drill from
drill-library(itsat-home-no-ballset covers most faults) — it is the single source of truth for drills, feel cues, and videos. - The YouTube link comes from
drill-libraryor a verified live search — never invent a URL; degrade gracefully (name the video/channel to search for) when web search isn't available. - Offer to save the drill with
training_plan(action="save")so "what's today's training?" recalls it and a later range session grades it.
Output Structure (Mobile-First)
1. Fault
- [One-line summary of what's wrong]
2. Root Cause
- [Why it's happening]
3. Drill
- [Name and basic setup]
4. Feedback Method
- [Prop needed + what correct looks/feels like]
- [Visual checkpoint or validation cue]
5. Equipment Needed
- [Budget tier: Free / $5–10 / $50+]
- [Specific item or household item]
6. Validation Checkpoint
- [How to know it worked before the range]
7. YouTube Reference
- [Link to video of drill executed correctly]
Format Requirements
- Mobile-optimized (short lines, scannable)
- Bold headers, no long paragraphs
- Action-oriented language
- Easy to read between reps
- No animations or complex visuals — this card is a deliberate exception to the coach's visual-first default: it's read on a phone mid-drill, so plain scannable text beats an HTML artifact here
What ships with it
1 file 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.

at-home-practice-feedback is a skill published in the GitHub repository bjornj12/golf-coach (1 stars, last pushed 1mo ago), licensed MIT. It adds 89 tokens to every session and 597 once invoked, about $0.0004 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 2026-08-31.
