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 | $0.00035 | $0.01274 |
| Opus 5 | $0.00017 | $0.00637 |
| Sonnet 5 | $0.00007 | $0.00255 |
| Haiku 4.5 | $0.00003 | $0.00127 |
Grade A, and why
opencli-browser 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.

OpenCLI Browser — Browser Automation for AI Agents
Control Chrome step-by-step via CLI. Reuses existing login sessions — no passwords needed.
Prerequisites
opencli doctor # Verify extension + daemon connectivity
Requires: Chrome running + OpenCLI Browser Bridge extension installed.
Critical Rules
- ALWAYS use
stateto inspect the page, NEVER usescreenshot—statereturns structured DOM with[N]element indices, is instant and costs zero tokens. - ALWAYS use
click/type/selectfor interaction, NEVER useevalto click or type —eval "el.click()"bypasses scrollIntoView and CDP click pipeline. - Verify inputs with
get value, not screenshots — aftertype, runget value <index>to confirm. - Run
stateafter every page change — afteropen,click(on links),scroll, always runstate. - Chain commands aggressively with
&&— combine commands to reduce overhead. evalis read-only — useevalONLY for data extraction, never for clicking, typing, or navigating.- Minimize total tool calls — plan your sequence before acting.
- Prefer
networkto discover APIs — most sites have JSON APIs. API-based adapters are more reliable than DOM scraping.
Core Workflow
- Navigate:
opencli browser open <url> - Inspect:
opencli browser state→ elements with[N]indices - Interact: use indices —
click,type,select,keys - Wait (if needed):
opencli browser wait selector ".loaded"orwait text "Success" - Verify:
opencli browser stateoropencli browser get value <N> - Repeat: browser stays open between commands
- Save: write a JS adapter to
~/.opencli/clis/<site>/<command>.js
Commands
Navigation
opencli browser open <url> # Open URL (page-changing)
opencli browser back # Go back (page-changing)
opencli browser scroll down # Scroll (up/down, --amount N)
Inspect (free & instant)
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.

opencli-browser is a skill published in the GitHub repository zxfccmm4/Obsidian-OpenCode-Knowledge (291 stars, last pushed 2mo ago), licensed MIT. It adds 35 tokens to every session and 1,274 once invoked, about $0.0002 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.
