What it does

Title Tag is an agent skill from kostja94/marketing-skills. When the user wants to write, audit, or optimize an HTML title tag, SEO title, page title, SERP title, browser-tab title, duplicate title, or title rewrite issue. For a sitewide metadata lifecycle including implementation and production validation, use page-metadata.

Its SKILL.md is about 720 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Marketing & SEO, covering On-page SEO. The repository describes itself as: Agent Skills for Marketing — SEO, Social, Influencer & More. 160+ open-source skills for SEO, content, 40+ page types, paid ads, channels, and strategies. Add project context… The licence is MIT.

When your agent uses it

  • Optimize an HTML title tag
  • Browser-tab title
  • Duplicate title
  • Title rewrite issue

Example prompts

  • “/title-tag”

What it can do on your machine

Read from SKILL.md and the folder at commit 8dd89c5. 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

    No scripts in the folder and no shell commands in SKILL.md.

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

  • Network

    Links to these hosts (documentation or services it may open):

    • developers.google.com

    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

Title Tag loads about 718 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 341 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~69
When it runs · the whole SKILL.md, loaded when a task matches
~718

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.

SEO On-Page: Title Tag

Owns writing and review rules for the HTML <title> element. page-metadata owns discovery, implementation, and release verification.

Inputs

Read root contextus.md when present. Confirm page type, unique page job, primary search intent, locale, current title and H1, verified differentiators, sibling-page titles, and whether a template automatically appends the brand.

Rules

  • Write a descriptive, concise, page-specific title that accurately represents the page.
  • Put the primary search concept early when natural; do not keyword-stuff.
  • Treat about 60 Latin characters for the title body as a default warning, not a hard limit. Pixel width, script, device, and query context affect display.
  • A delimiter plus brand suffix such as | Brand is outside that title-body target. It may be truncated or rewritten; include it only when useful and never duplicate a template suffix.
  • For CJK, RTL, or other scripts, review rendered width and natural language instead of applying a translated character formula.
  • Title and H1 must serve the same page intent and promise, but need not use identical wording. Example: title AI Image Generator; H1 Generate Images with AI.
  • Include only claims supported by the page. Do not add a year, number, superlative, or feature merely for click appeal.
  • Apply the Swap Test: if the title fits a sibling page unchanged, add a verified page-specific fact or sharpen its task.
  • Google may generate a different title link from the <title>, main visual title, headings, prominent text, anchors, og:title, or other signals. Optimize consistency of page identity, not control of the exact displayed string.

Cannibalization

When multiple URLs target the same primary intent, report the affected URLs, overlap, and evidence. Do not merge pages, reassign keywords, change page roles, or alter information architecture.

Output

  • Recommended title, with the title body and optional brand suffix shown separately.
  • A length or width warning when relevant, never a mechanical pass/fail.
  • Brief rationale tied to intent and unique page facts.
  • H1 semantic-alignment result; actual H1 edits route to heading-structure.
  • Cannibalization warning when applicable.

Primary reference

  • page-metadata, meta-description, heading-structure
  • localization-strategy, translation, google-search-console
