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.

SkillSpector: 2 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- medium Data Exfiltration · line 69 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
- medium Memory Poisoning · line 425 Skill attempts to fill the context window with filler content, displacing legitimate instructions and safety constraints. This can degrade agent performance or bypass safety boundaries.Fix: Implement context-window management that detects and rejects padding or stuffing attempts. Prioritize system instructions over user-injected content.
What it costs to keep this loaded
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 | $0.00026 | $0.07794 |
| Opus 5.5 | $0.00010 | $0.03118 |
| Sonnet 5.5 | $0.00005 | $0.01559 |
| Haiku 4.5 | $0.00003 | $0.00779 |
Grade A, and why
browse scanned grade A with 1 finding 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 16d 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.

The opening of the file, as written. The whole thing — 578 lines — stays where its author put it; the contents beside it link to each section on GitHub.
When to invoke
Use when you need to test a feature, verify a deployment, dogfood a user flow, or file a bug with evidence. Use when asked to "open in browser", "test the site", "take a screenshot", or "dogfood this".

browse: QA Testing & Dogfooding
Persistent headless Chromium. First call auto-starts (~3s), then ~100ms per command. State persists between calls (cookies, tabs, login sessions).
SETUP (run this check BEFORE any browse command)
B="${CLAUDE_SKILL_DIR:-$HOME/.claude/skills/browse}/bin/vibe-browse"
[ -x "$B" ] || B="$(command -v vibe-browse || true)"
if [ -n "$B" ] && [ -x "$B" ] && [ "$("$B" status 2>/dev/null)" != "BROWSE_NOT_AVAILABLE" ]; then
echo "READY: $B"
echo "BROWSE_BIN: $B"
else
echo "NEEDS_SETUP"
fi
Every Bash call starts a fresh shell, so $B is unset in every later block.
A block that runs a browse command starts with B='<BROWSE_BIN>': replace
<BROWSE_BIN> with the path printed on the BROWSE_BIN: line.
vibe-browse is a launcher, not the browser itself. With the checkout's
dependencies installed it runs the full daemon this file documents; without
them it falls back to a stateless shim that covers navigation, capture and
chain but answers NOT_SUPPORTED:<verb> to the interaction and inspection
verbs. Read that answer as a missing capability rather than a transient
failure: name the verb that was unavailable instead of retrying it or
describing output you never got.
What ships with it
5 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.

browse is a skill published in the GitHub repository timurgaleev/vibestack (7 stars, last pushed 10d ago), licensed MIT. It adds 26 tokens to every session and 7,794 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
