What it does

Form Palette is an agent skill from jeremylongshore/tons-of-skills-marketplace. Use when asked to generate a color palette, create industry-matched colors, or pick colors for a product type. Examples: "color palette for fintech", "healthcare app colors", "SaaS brand colors"

Its SKILL.md is about 770 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `.claude-plugin/plugin.json`).

It sits in Frontend & Design, covering Theming and dark mode, Banking and insurance and Logo and visual identity. The repository describes itself as: Model-agnostic agent-skills platform with a harness-free canonical layer, verified adapters, and the ccpi package manager. Explore at tonsofskills.com. The licence is MIT.

When your agent uses it

  • Asked to generate a color palette
  • Create industry-matched colors
  • Pick colors for a product type

Example prompts

  • “color palette for fintech”
  • “healthcare app colors”
  • “SaaS brand colors”
  • “/form-palette”

Requirements

  • Python 3
  • Pre-approved tools (allowed-tools): Read, Bash, Glob, Grep

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. Identify product type from user request or project context
  2. Search product reasoning
  3. Search color conventions
  4. Output a full shadcn-compatible token set using the format below

What it can do on your machine

Read from SKILL.md and the folder at commit cfae287. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Bash
    • Glob
    • Grep

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • python3

    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

Form Palette loads about 772 tokens when it runs. Until then it costs about 52 tokens; SKILL.md has 155 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~52
When it runs · the whole SKILL.md, loaded when a task matches
~772

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Bash, Glob, Grep

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); files beside SKILL.md are not scanned.

form-palette — Color Palette Generation

Follow the output format defined in docs/output-kit.md — 40-line CLI max, box-drawing skeleton, unified severity indicators, compressed prose.

When to use

Product needs a color palette. Industry or product type is known or discoverable from context.

Workflow

  1. Identify product type from user request or project context
  2. Search product reasoning:
    bash
    python3 -m form_agent.uiux search --domain product --query "{product_type}" --limit 3
  3. Search color conventions:
    bash
    python3 -m form_agent.uiux search --domain color --query "{product_type}" --limit 3
  4. Output a full shadcn-compatible token set using the format below

Output format

Anti-patterns

  • Never violate WCAG AA contrast (4.5:1 for normal text, 3:1 for large text)
  • Never ignore industry color conventions (e.g., red for destructive, green for success)
  • Never output tokens without both light and dark values
  • Never reuse the same hue for Primary and Destructive

Delivery

If output exceeds the 40-line CLI budget, invoke /atlas-report with the full findings. The HTML report is the output. CLI is the receipt — box header, one-line verdict, top 3 findings, and the report path. Never dump analysis to CLI.
