Comment Block

Insert structured, visually framed comments directly into user code around a complete feature, section, or logical block.

Origin

• Author: Carlos Fachini
• Source: https://github.com/carlosfachini/comment-block-skill
• License: MIT

Operating Modes

• Assisted mode, default: analyze the active file, diff, selection, or surrounding code. Propose type, title, body, date, optional author, and insertion location. Ask for confirmation before editing.
• Manual mode: when the user says comment-block manual or use comment-block manual, ask only for missing title and body. Use FEATURE unless the user provides or clearly implies another type.
• Quick mode: when the user writes comment-block: Title | Body, parse the left side as title and the right side as body. Confirm only when the insertion location is ambiguous or risky.
• Config mode: when the user says comment-block config, explain optional settings: default author, default type, confirmation behavior, and language detection preferences. Do not edit code unless asked.

Comment Data

• type: one of FEATURE, SECTION, LOGIC, TODO, BUGFIX, REFACTOR, NOTE.
• Default type: FEATURE.
• Infer type from wording when clear. Examples: "fix" -> BUGFIX, "refactor" -> REFACTOR, "todo" -> TODO, "note" -> NOTE, "logic" -> LOGIC, "section" -> SECTION.
• title: concise, uppercased in the inserted block.
• date: current local date in YYYY-MM-DD.
• author: optional. Include only when configured or explicitly requested, such as "with author Carlos".
• body: one or more clear sentences describing why the block exists.

Assisted Confirmation

Before editing in assisted mode, show:

Suggestion:
Type: FEATURE
Title: Final Price Calculation
Body: Centralizes subtotal, discount, and total rules displayed in the summary.
Date: 2026-04-24
Location: before the PriceSummary component.

Apply?

Proceed only after confirmation. If the user already supplied exact content and an unambiguous location, a brief confirmation is enough.

Placement Rules

• Insert before the complete feature, section, declaration, selector, component, route, function, class, block, or template node being documented.
• If the user asks for wrapping a region and the syntax supports comments after the region, place a matching end comment after the complete region. Otherwise use the preferred single block format that contains both [START: TYPE] and [END: TYPE] before the region.
• Never insert inside string literals, template literal content, JSX prop lists, tag attributes, object keys, import/export clauses, decorators, or partially selected syntax.
• Do not comment strict .json. Only comment JSON-like files when they are JSONC, JSON5, VS Code settings, or another comments-enabled format.
• In mixed PHP files, choose syntax from the current region: PHP code uses /* */; HTML/template regions use <!-- -->.
• Ask for clarification when multiple plausible blocks match the request or when the only possible insertion point may break syntax.

Syntax Selection

Use the smallest valid comment wrapper for the current language context. Inside that wrapper, always use the Comment Block visual frame:

• A [START: TYPE] line.
• A full-width # border line.
• Metadata and body lines wrapped with || side rails.
• A full-width # border line.
• An [END: TYPE] line.

Prefer a readable fixed frame width around 72 characters when practical. Pad || lines with spaces so the closing || aligns. If content is longer than the frame width, wrap it across multiple || lines instead of widening the frame excessively.

HTML And Vue Templates

<!-- [START: FEATURE]
########################################################################
|| Title: HERO SECTION                                                ||

||                                                                    ||
|| Defines the main visible landing section.                          ||
########################################################################
[END: FEATURE] -->
<section>...</section>

React JSX And TSX

Use JSX block comments outside prop lists and inside JSX expression braces:

{/* [START: FEATURE]
########################################################################
|| Title: FINAL PRICE CALCULATION                                     ||
|| Date: 2026-04-24                                                   ||
||                                                                    ||
|| Centralizes subtotal, discount, and total rules.                   ||
########################################################################
[END: FEATURE] */}
<PriceSummary />

In normal JavaScript or TypeScript regions of a JSX/TSX file, use /* */.

JavaScript, TypeScript, CSS, PHP Code, JSONC

/* [START: FEATURE]
########################################################################
|| Title: FINAL PRICE CALCULATION                                     ||

||                                                                    ||
|| Centralizes subtotal, discount, and total rules.                   ||
########################################################################
[END: FEATURE] */

Formatting Rules

• Preserve surrounding indentation.
• Add exactly one empty || || rail line between metadata and body.
• Add Author: ... immediately after Date: ... when author is included.
• Keep title uppercase in the inserted block.
• Always include the visual # border and || side rails.
• Prefer ASCII punctuation unless the surrounding file already uses a different convention.
