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 | $0.00090 | $0.01268 |
| Opus 5 | $0.00045 | $0.00634 |
| Sonnet 5 | $0.00018 | $0.00254 |
| Haiku 4.5 | $0.00009 | $0.00127 |
Grade A, and why
trackman-visualizer 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 10d 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 — 100 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Trackman Visualizer
Turn a coaching diagnosis into a self-contained animated HTML artifact that animates the golfer's real measured flight: a side-view height profile (launch → apex → landing → roll), a top-down shape view with every shot's tracer, the swing path that explains why it curves, progress vs targets, and a Fix it section linking drills for both the range and home. Uses real shot data — no invented shapes, no freehand diagrams.
When to use
After golf-coaching produces a diagnosis (or when the user asks to "see" /
"draw" / "animate" their slice, flight, dispersion, or progress). It's a
presentation layer on top of the coach — it adds no new diagnosis.
Be proactive. Don't wait to be asked — build this page whenever you diagnose a fault, show a shot pattern, or hand over drills. One page carries the whole story: what the ball is doing, why, and the exercises that fix it.
Inputs to gather
Reuse what the coach already pulled, or fetch via the MCP:
- Shots — per-shot measurements for the club under discussion, from
trackman(action="session", activity_id=...):launchDirection,launchAngle,carry,total,totalSide,curve,maxHeight,landingAngle,hangTime. Pass every shot (that's what makes the dispersion visible); the page animates the average and draws the rest faint. Missing fields are fine — the page only labels what was measured. - Swing —
clubPath,faceAngle,faceToPath(mean over those shots), where the session kind captures them. - Targets — from the saved plan (
training_plan(action="next")/training_plan(action="list")) and/ortraining_plan(action="verify"): each as{label, value, target, low, high, met}. - Blocks — the prescribed drills, each tagged
where: "range"orwhere: "home", each with 1–3 verified links (links: [{label, url}]) fromdrill-libraryor live search. Never invent URLs.
Also note handedness (profile.dexterity) — it sets which way "right" is.
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.

trackman-visualizer is a skill published in the GitHub repository bjornj12/golf-coach (1 stars, last pushed 1mo ago), licensed MIT. It adds 90 tokens to every session and 1,268 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.
