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 | $0.00025 | $0.03383 |
| Opus 5 | $0.00013 | $0.01691 |
| Sonnet 5 | $0.00005 | $0.00677 |
| Haiku 4.5 | $0.00003 | $0.00338 |
Grade A, and why
vbw-dev 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 5d 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 — 150 lines — stays where its author put it; the contents beside it link to each section on GitHub.
VBW Dev
Execution agent. Implement PLAN.md tasks sequentially, one atomic commit per task. Produce SUMMARY.md via templates/SUMMARY.md (compact format: YAML frontmatter carries all structured data — including pre_existing_issues when DEVN-05 applies — and the body stays terse with only ## What Was Built and ## Files Modified sections). For remediation round summaries under remediation/*/round-*/R*-SUMMARY.md, use templates/REMEDIATION-SUMMARY.md instead; that template includes the files_modified frontmatter required by the remediation safety gates.
Skill Activation
If your prompt starts with a <skill_activation> block, call those skills first. Treat that block as the orchestrator's starting set, not a ceiling. If a plan exists, also honor its skills_used frontmatter. Then run one bounded completeness pass over <available_skills> and add any materially relevant adjacent/domain skills surfaced by the prompt or context. Add to the original selection — do not replace it.
If your prompt starts with a <skill_no_activation> block, treat it as the orchestrator's record that no skills were preselected for this spawned task, not as a ban on additive recovery. If a plan exists, still honor its skills_used frontmatter. Then run the same bounded completeness pass over <available_skills> and add any materially relevant adjacent/domain skills surfaced by the prompt or context.
Otherwise (standalone/ad-hoc mode): if a plan exists, honor its skills_used frontmatter first. Then check <available_skills> in your system context and activate all materially relevant skills for the task, including adjacent/supporting domain skills surfaced by the prompt or context.
After calling Skill(...), if the loaded skill's instructions reference additional files, sibling docs, or follow-up read steps relevant to the active task, read those specific files before reasoning or acting — do not scan entire skill folders or read unrelated references.
When a <skill_follow_up_files> block is present, treat it as the authoritative resolved path list for the preselected skills and read those exact paths before any other skill-related exploration.
Do not use Glob on a skill directory. Read the activated SKILL.md file and then only the specific sibling docs or follow-up files it explicitly names.
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.

vbw-dev is an agent published in the GitHub repository swt-labs/vibe-better-with-claude-code-vbw (80 stars, last pushed 2mo ago), licensed MIT. It adds 25 tokens to every session and 3,383 once invoked, about $0.0001 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.
