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 | $0.01546 | $0.01546 |
| Opus 5 | $0.00773 | $0.00773 |
| Sonnet 5 | $0.00309 | $0.00309 |
| Haiku 4.5 | $0.00155 | $0.00155 |
Grade A, and why
skills CLAUDE.md 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 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.

Repository Structure
skills/migration/
migrate-page/SKILL.md Cone-only: orchestrates full page migration
migrate-block/SKILL.md Scoop: migrates a single block with visual verification
migrate-header/SKILL.md Scoop: migrates header/nav with EDS header block pattern
dismiss-overlays/SKILL.md Reference: overlay dismissal patterns
docs/specs/ Design docs and implementation plans
Skills live under a top-level skills/ directory (Anthropic skills convention),
with migration/ as a category subdir. Install commands target
--path skills/migration. Slicc's upskill flattens the inner skill folders
into /workspace/skills/<name>/ at runtime — so internal references like
/workspace/skills/migrate-page/scripts/... are unaffected by the source layout.
Slicc Browser Automation Conventions
Skills run inside Slicc and use playwright-cli for browser automation.
Stateless Tab Targeting (since slicc PR #188)
Every playwright-cli command that operates on a tab requires explicit
--tab <targetId>. There is no implicit "current tab".
Capture targetId from output:
# tab-new returns a targetId
playwright-cli tab-new https://example.com
# Output: "Created tab <targetId> at https://example.com"
# Capture <targetId> as {sourceTabId}
# open also returns a targetId (and does NOT broadcast/steal focus)
open /shared/my-site/drafts/hero-preview.html
# Output: "... (targetId: <targetId>)"
# Capture <targetId> as {previewTabId}
Use --tab on every command:
playwright-cli eval --tab={sourceTabId} "document.title"
playwright-cli screenshot --tab={previewTabId} --max-width=1440 --filename=out.png
playwright-cli snapshot --tab={previewTabId}
playwright-cli goto --tab={previewTabId} {url}
playwright-cli tab-close --tab={sourceTabId}
Commands without --tab: tab-list (lists all tabs), tab-new (creates a tab).
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.

skills CLAUDE.md is an instructions file published in the GitHub repository aemcoder/skills (2 stars, last pushed 5d ago), licensed Apache-2.0. It adds 1,546 tokens to every session, about $0.0077 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
