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 | $0.00138 | $0.01756 |
| Opus 5 | $0.00069 | $0.00878 |
| Sonnet 5 | $0.00028 | $0.00351 |
| Haiku 4.5 | $0.00014 | $0.00176 |
Grade A, and why
trailhead-chart 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 — 44 lines — stays where its author put it; the contents beside it link to each section on GitHub.
trailhead-chart is the chart cluster of the trailhead skill: the verbs that give a map its start or bring outside work into it. new charts a new map from a loose idea; adopt maps an existing codebase into a map; ticket opens a ticket of any type on the fly; inbox triages issues opened by others; grill runs a standalone grilling session. Everything lives on the GitHub Issues; the repo holds code only.
Load first, in order
Before doing anything, read ../_shared/load-first.md and follow it: the shared-core load contract (the six core files, in order, then the effective config). _shared/ is a sibling of this cluster's own directory (at ../_shared/), never a child of it; its absence from a listing of the cluster dir is expected, not a missing core.
Routing: verb to engine
The first word of the arguments is the verb; the rest is the text (a loose idea, a <type> <title>, an issue number, or a topic).
new/adopttoreferences/charting.md: how a map is born (Mode 1 and Mode 1-bis). Read that file.ticket <type> <title>to the Open a ticket on the fly engine below.inbox [issue]toreferences/inbox.md: the triage protocol. Read that file.grill [topic|ticket]to the Standalone grill engine below.
The cross-cluster situational references and the technique bodies these engines call live in _shared/; this cluster names each by its ../_shared/... path where it needs one (the gh cookbook, the out-of-scope rules, teamwork, the techniques).
Chart a new map / adopt a project: new, adopt
Read references/charting.md and follow it. It holds both protocols: Mode 1 (chart a new map: name the destination, map the frontier breadth-first, harvest parked work from earlier maps, create the map plus the first-use repo setup, the per-map label, conventions, and the dashboard, create-then-wire the tickets, fire the research, offer config) and Mode 1-bis (adopt an existing project: map the codebase once into the repo's trailhead:codebase issue, backfill the decisions already embodied in the code, detect a monorepo / submodules / path-bound tooling to seed the isolation: convention, then map the frontier of the remainder). At the end of chart or adopt, make the First-time config offer (below).
What ships with it
2 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.

trailhead-chart is a skill published in the GitHub repository ToRvaLDz/trailhead (5 stars, last pushed 3d ago), licensed MIT. It adds 138 tokens to every session and 1,756 once invoked, about $0.0007 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.
