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 | $0.00103 | $0.06046 |
| Opus 5 | $0.00051 | $0.03023 |
| Sonnet 5 | $0.00021 | $0.01209 |
| Haiku 4.5 | $0.00010 | $0.00605 |
Grade A, and why
playwright-cli 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 yesterday.
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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
- **Calling the app's own backend? Use `curlwright`, not `eval-file`.** It is curl's flags run by a `fetch()` inside the tab, so cookies, origin and session come along: `curlwright -s -X POST https://app.example.com/api/ How it starts

Browser Automation via playwright-cli
Use playwright-cli (also aliased as playwright and puppeteer) via the bash tool for all browser automation.
Every tab-operating command requires --tab=<targetId>. There is no implicit "current tab". Always specify which tab you're operating on.
playwright-cli <command> --help prints that command's usage and does nothing else — safe to run before any action.
Quick Start
# 1. Open a page — note the targetId in the output
playwright-cli open https://example.com
# Output: Opened https://example.com in new tab [targetId: E9A3F...]
# 2. Take a snapshot to see the page structure and get element refs
playwright-cli snapshot --tab=E9A3F
# 3. Interact using refs from the snapshot (e.g. e5, e12)
playwright-cli click --tab=E9A3F e5
playwright-cli fill --tab=E9A3F e12 "hello world"
# 4. Re-snapshot after interactions (refs change)
playwright-cli snapshot --tab=E9A3F
Tab IDs
tab-listshows all tabs with their targetIds. The user's active tab is marked(active).tab-new/openreturn the new tab's targetId — capture it for subsequent commands.- Use
--tab=<targetId>on ALL commands that operate on a tab.
Frame IDs
frames --tab=<targetId>lists frame IDs. A frame ID is not a tab target ID; never pass it to--tab.- Use
--tab=<targetId> --frame=<frameId>witheval,eval-file, orsnapshotto target a child frame, including cross-origin frames. - A frame-scoped
snapshotprints only that frame's accessibility subtree. Its frame-prefixed refs work withclick,fill,dblclick,hover,select,check, anduncheck; do not pass--frameto those commands. Other ref commands require refs from a top-level snapshot.
Common Failure Modes
--tab <targetId> is required— you forgot--tab=<id>. Runtab-listto get IDs.is a frame ID, not a tab target ID— keep the owning tab's targetId in--taband pass the frame ID with--frame.No snapshot available— runsnapshot --tab=<id>before using refs.unknown flag "--x"/unexpected argument "y"— every subcommand rejects arguments it does not support, so an exit code of 0 means everything you passed was honoured. Check<verb> --help.- For free-text payloads that start with
-(e.g.fill/type/eval), put--before the text:fill --tab=<id> e1 -- --dash-looking. is not an element ref— a screenshot's positional is a main-frame element ref (e5); the output path is--filename=<path>. Frame-prefixed refs (f1e5) clip only withclick-family commands.- Refs are tied to one tab + one snapshot. They do not carry across tabs, navigations, or reloads.
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.

playwright-cli is a skill published in the GitHub repository ai-ecoverse/slicc (30 stars, last pushed yesterday), licensed Apache-2.0. It adds 103 tokens to every session and 6,046 once invoked, about $0.0005 per session on Opus 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 2026-09-05.
