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 | $0.00102 | $0.00567 |
| Opus 5 | $0.00051 | $0.00283 |
| Sonnet 5 | $0.00020 | $0.00113 |
| Haiku 4.5 | $0.00010 | $0.00057 |
Grade A, and why
golf-practice-at-home 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.
What it actually says
Practice at Home (no ball, no range)
This is a thin pointer — the logic lives elsewhere. An at-home / no-ball routine is already first-class in the coach, so don't re-implement it here:
golf-coachingrule 4 already mandates at least one at-home / no-ball block in every plan (and its at-home flavor builds a full home routine).drill-libraryholds theat-home-no-balldrill set — the single source of truth for those drills, their feel cues, and their videos.training_plan(action="save")persists the routine and later grades it.
When the user asks for a home / no-ball routine ("what can I do at home / without a ball / no range"):
- Run
golf-coachingin its at-home flavor — reuse the existing diagnosis (training_plan(action="next"), or a quicktrackman-stats-analysisread), then build the plan. - Pull drills from
drill-library'sat-home-no-ballset, matched to the diagnosed fault (over-the-top / out-to-in → wall, pump-and-drop, step-through; open face → split-hands release, mirror face check; both → trail-arm-only throws). - Present it home-first: a 5–10 min ordered daily block (transition → path →
face), reps + one feel per drill, videos where available (from
drill-libraryor a verified live search — never invented), rendered viatrackman-visualizeraswhere: "home"Fix-it blocks. - Save it with
training_plan(action="save")so "what's today's training?" recalls and grades it next range session.
Everything above is golf-coaching + drill-library behavior — this skill only
routes there so the at-home path isn't a second full copy that drifts. Close by
telling the user to do it daily and that you'll check it against their numbers
next range session.
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.

golf-practice-at-home is a skill published in the GitHub repository bjornj12/golf-coach (1 stars, last pushed 1mo ago), licensed MIT. It adds 102 tokens to every session and 567 once invoked, about $0.0005 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.
