Conciseness

The body is lean and assumes Claude's competence — it never explains what Flet, a blog post, or pip is, and every directive ('Keep writing practical and concise', 'Avoid excessive emoji') earns its place.

Actionability

Provides concrete executable commands and code — 'pip install "flet[all]" --upgrade', the 'uv sync --upgrade-package flet ...' block, and rg/sed/mkdir/cp patterns — with template variables only where flexibility is justified.

Workflow Clarity

A 7-step numbered workflow with an explicit validation checkpoint — step 7 'Verify before handoff' enumerates title/slug, image paths, link resolution, and changelog accuracy — plus an output checklist.

Progressive Disclosure

A single well-organized file split into clear sections (Inputs, Style targets, Workflow, Commands, Checklist) with no nested or deep references; nothing is awkwardly inline given the absence of bundle files.

Specificity

Lists multiple concrete actions and components — 'Create or update a Flet release announcement blog post from changelog notes' plus 'major feature sections, screenshots, code samples, upgrade instructions (pip and uv/pyproject.toml)' — rather than vague language.

Completeness

Explicitly answers both what (create/update a release blog post with the listed sections) and when ('Use when asked to draft, plan, or revise posts...'), with an explicit 'Use when' trigger clause.

Trigger Term Quality

Includes natural phrasing a user would say — 'draft, plan, or revise posts like "Flet X.Y.Z release announcement"' — covering common request variations.

Distinctiveness Conflict Risk

The 'Flet release announcement blog post' niche with version-specific triggers is highly specific and unlikely to fire for unrelated skills.
