What it does

Prompt For Update 482487 Greasyfork Dark is an agent skill from cyfung1031/userscript-supports. Update the Greasy Fork Dark userscript's existing hard-coded // general CSS snapshot to the latest Greasy Fork application CSS while preserving the owner's dark palette, comments, selector-specific overrides, supplemental styles, and runtime architecture. Use when 482487-greasyfork-dark.user.js needs a CSS structure refresh, selector/media/layering update, or current application stylesheet comparison.

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 29 other files, including scripts and reference files (for example `agents/openai.yaml`, `examples/mini-greasyfork-dark.user.js` and `references/color-policy.md`).

It sits in Frontend & Design, covering CSS and styling. The repository describes itself as: This is for the userscripts created on GreasyFork.org. The licence is MIT.

When your agent uses it

  • 482487-greasyfork-dark.user.js needs a CSS structure refresh
  • Selector/media/layering update
  • Current application stylesheet comparison

Example prompts

  • “/prompt-for-update-482487-greasyfork-dark”

Requirements

  • Python 3
  • Node.js

What it can do on your machine

Read from SKILL.md and the folder at commit a6a319e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 3 files in scripts/ (Python and JavaScript, from the files we listed), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Prompt For Update 482487 Greasyfork Dark loads about 1k tokens when it runs, and up to ~10k if it reads all its reference files. Until then it costs about 111 tokens; SKILL.md has 418 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~111
When it runs · the whole SKILL.md, loaded when a task matches
~1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~10k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

description
Update the Greasy Fork Dark userscript's existing hard-coded // general CSS snapshot to the latest Greasy Fork application CSS while preserving the owner's dark palette, comments, selector-specific overrides, supplemental styles, and runtime architecture. Use when 482487-greasyfork-dark.user.js needs a CSS structure refresh, selector/media/layering update, or current application stylesheet comparison.

Greasy Fork Dark CSS snapshot update

Use this skill for the one-file userscript update task. Read the agent guide at the cssTextFn boundary in 482487-greasyfork-dark.user.js before editing.

Core contract

  • Update the one existing // general template literal in place. Never append a second application CSS snapshot.
  • Treat the raw current application CSS as the structure/non-color-token oracle and the historical // general snapshot as the owner styling oracle. Formatted copies are navigation aids only.
  • Treat the actual target script, especially its current or HEAD // general declarations, as authoritative for colors and comments. Reference files contain examples and procedure only; they may become stale.
  • Preserve attached CSS comments, hard-coded colors, selector-specific overrides, and webhook/userscript/extension/PrettyPrint/stats supplemental templates. If the old snapshot has a detached /* Preserved comments from the previous // general snapshot. */ catalogue, treat it as stale migration debris: do not copy the catalogue or its detached tokens; recover each item only from its real declaration/rule when present.
  • Exclude active :root variables and the official prefers-color-scheme dark branch. Preserve the user's own dark-theme design.
  • Do not redesign cssTextFn, removeNonColor, generalCSSFn, lifecycle timing, filtering, or style injection.
  • Use PickInvariant as a focused structural audit: bind the owner snapshot, current browser-observed CSS, and these invariants before committing.

Load by phase

  • Update procedure, source/version mapping, merge rules, and stop condition: read references/workflow.md.
  • Published adjacent-version patterns and the routing classifier: read references/lineage-deltas.md and run scripts/classify_lineage.py when version sources are available.
  • Reading the existing JavaScript and converting upstream CSS into the snapshot: read references/source-and-conversion.md.
  • Snapshot indentation, ordering, comments, and focused-diff rules: read references/format-contract.md before editing.
  • Source declaration tokens and maintainable comment placement: read references/source-fidelity.md before converting CSS.
  • Source-to-snapshot formatting/cascade harness: run scripts/audit_css_format.py with --strict before accepting the diff.
  • Snapshot-ready whitespace/newline conversion: run scripts/format_css_snapshot.py with the raw CSS and actual previous snapshot. It transfers source structure/layout, overlays recognized owner colors and --gfdark-* declarations, carries attached owner comments, and preserves complete owner-only rules; review the result before inserting it.
  • Before/after diff justification: run scripts/audit_snapshot_diff.py with the raw CSS and reject FORMAT-ONLY hunks or non-general runtime changes without separate evidence.
  • Color substitutions and changed-selector policy: read references/color-policy.md.
  • Deterministic checks and failure interpretation: read references/mechanical-checks.md.
  • Concrete passing/failing command examples: read references/examples.md.

Required handoff

Run the bundled checker, all fixture tests including tests/test_snapshot_diff.py, JavaScript syntax and diff checks, obtain independent read-only sub-agent verification, commit incrementally, and push/update the PR only after all checks pass. Treat these as best-effort double confirmation; the actual script, format contract, focused diff, and owner comments remain primary. Keep the final diff limited to the requested target and skill artifacts.
