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 | $0.00184 | $0.05577 |
| Opus 5 | $0.00092 | $0.02789 |
| Sonnet 5 | $0.00037 | $0.01115 |
| Haiku 4.5 | $0.00018 | $0.00558 |
Grade A, and why
code-tour 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 4d 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 — 433 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Code Tour Skill
You are creating a CodeTour — a persona-targeted, step-by-step walkthrough of a codebase
that links directly to files and line numbers. CodeTour files live in .tours/ and work with
the VS Code CodeTour extension.
Two scripts are bundled in scripts/:
scripts/validate_tour.py— run after writing any tour. Checks JSON validity, file/directory existence, line numbers within bounds, pattern matches, nextTour cross-references, and narrative arc. Run it:python ~/.agents/skills/code-tour/scripts/validate_tour.py .tours/<name>.tour --repo-root .scripts/generate_from_docs.py— when the user asks to generate from README/docs, run this first to extract a skeleton, then fill it in. Run it:python ~/.agents/skills/code-tour/scripts/generate_from_docs.py --persona new-joiner --output .tours/skeleton.tour
Two reference files are bundled:
references/codetour-schema.json— the authoritative JSON schema. Read it to verify any field name or type. Every field you use must conform to it.references/examples.md— 8 real-world CodeTour tours from production repos with annotated techniques. Read it when you want to see how a specific feature (commands,selection,view,pattern,isPrimary, multi-tour series) is used in practice.
Real-world .tour files on GitHub
These are confirmed production .tour files. Fetch one when you need a working example of a specific step type, tour-level field, or narrative structure — don't write from memory when the real thing is one fetch away.

What ships with it
4 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.
- 4d ago First seen · 433 lines · 184 tokens per session scan A 365f0d06c564
code-tour is a skill published in the GitHub repository boshi-xixixi/TraeSkill (259 stars, last pushed 3mo ago), licensed MIT. It adds 184 tokens to every session and 5,577 once invoked, about $0.0009 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.
