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 | $0.00073 | $0.01625 |
| Opus 5 | $0.00036 | $0.00813 |
| Sonnet 5 | $0.00015 | $0.00325 |
| Haiku 4.5 | $0.00007 | $0.00162 |
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 6d 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 — 141 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Code Tour
Create CodeTour files — persona-targeted, step-by-step walkthroughs of a codebase that link directly to files and line numbers. CodeTour files live in .tours/ and work with the VS Code CodeTour extension.
Overview
A great tour is a narrative — a story told to a specific person about what matters, why it matters, and what to do next. Only create .tour JSON files. Never modify source code.
When to Use This Skill
- User asks to create a code tour, onboarding tour, or architecture walkthrough
- User says "tour for this PR", "explain how X works", "vibe check", "RCA tour"
- User wants a contributor guide, security review, or bug investigation walkthrough
- Any request for a structured walkthrough with file/line anchors
Core Workflow
1. Discover the repo
Before asking anything, explore the codebase:
In parallel: list root directory, read README, check config files. Then: identify language(s), framework(s), project purpose. Map folder structure 1-2 levels deep. Find entry points — every path in the tour must be real.
If the repo has fewer than 5 source files, create a quick-depth tour regardless of persona — there's not enough to warrant a deep one.
2. Infer the intent
One message should be enough. Infer persona, depth, and focus silently.
| User says | Persona | Depth |
|---|---|---|
| "tour for this PR" | pr-reviewer | standard |
| "why did X break" / "RCA" | rca-investigator | standard |
| "onboarding" / "new joiner" | new-joiner | standard |
| "quick tour" / "vibe check" | vibecoder | quick |
| "architecture" | architect | deep |
| "security" / "auth review" | security-reviewer | standard |
| (no qualifier) | new-joiner | standard |
When intent is ambiguous, default to new-joiner persona at standard depth — it's the most generally useful.
3. Read actual files
Every file path and line number must be verified. A tour pointing to the wrong line is worse than no tour.
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.

code-tour is a skill published in the GitHub repository bestagentkits/agency-skills (10 stars, last pushed 2mo ago), licensed MIT. It adds 73 tokens to every session and 1,625 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 2026-09-03.
