What it does

Review Sheet is an agent skill from iancooper/practical-messaging. Build and publish a Practical Messaging artwork review sheet — the page Ian reviews figures on, because he cannot see PNGs in a terminal. Carries the generator's requirements (inlined data URIs, styles.md palette, an address on every claim, light in both themes), the publish etiquette, and the nine sheets already out. Use when a batch of artwork needs review, when findings come back, or when asked to republish a sheet.

Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

When your agent uses it

  • A batch of artwork needs review
  • Findings come back
  • Asked to republish a sheet

Example prompts

  • “/review-sheet”

Requirements

  • Python 3

Workflow steps

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

  1. Inline every PNG as a base64 data URI. The artifact CSP blocks local files and external
  2. Set the page in styles.md's own palette and faces, so the red on the page is the red in
  3. Give every claim an address he can quote back — A4·1, B2·2. **He reads line by line
  4. Keep the plate light in both themes. The page renders in the viewer's theme, and **a
  5. Say what is being asked. A sheet that shows work without naming the decision gets looked

What it can do on your machine

Read from SKILL.md and the folder at commit 5d0ea23. 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

    Shell commands in SKILL.md call:

    • python3
    • git

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

  • Network

    No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.

    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

Review Sheet loads about 2.8k tokens when it runs. Until then it costs about 109 tokens; SKILL.md has 1,662 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~109
When it runs · the whole SKILL.md, loaded when a task matches
~2.8k

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); files beside SKILL.md are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 1,662 words (~2,751 tokens).

“Ian cannot review PNGs in a terminal, and he reviews by looking. Every finding on this work so far — six on legibility, two rulings on the composed figures — arrived through one of these pages. A batch of artwork…”
