At a glance

A specialized skill for the sns-strategist and visual-planner agents covering platform algorithms.

  • Works in 5 steps: First 1 second is everything:… → 15-30 seconds optimal: Maximize… → Loop structure: End flowing into… → …
  • Exposure optimization
  • SKILL.md covers Why Understanding Algorithms…, Instagram Algorithm (2025…, TikTok Algorithm and LinkedIn Algorithm, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Platform Algorithms is an agent skill from revfactory/harness-100. A specialized skill for the sns-strategist and visual-planner agents covering platform algorithms. Provides how recommendation algorithms work and reach optimization strategies for Instagram, TikTok, LinkedIn, and X. Use for 'algorithm,' 'reach rate,' 'exposure optimization,' 'feed algorithm,' and similar topics.

Its SKILL.md is about 1.2k 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 Writing & Content. It works with Instagram, LinkedIn and TikTok. The licence is Apache-2.0.

When your agent uses it

  • Exposure optimization

Example prompts

  • “algorithm,”
  • “reach rate,”
  • “exposure optimization,”
  • “/platform-algorithms”

Workflow steps

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

  1. First 1 second is everything: Visual/text hook to stop scrolling
  2. 15-30 seconds optimal: Maximize completion rate (longer videos reduce completion)
  3. Loop structure: End flowing into beginning encourages re-watching
  4. Trending sounds: Using popular music/audio boosts exposure
  5. Text overlay: Subtitles essential for muted viewers

What it can do on your machine

Read from SKILL.md and the folder at commit 8e8d35c. 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

    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

Platform Algorithms loads about 1.2k tokens when it runs. Until then it costs about 84 tokens; SKILL.md has 468 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~84
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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.

Platform Algorithms — Platform Algorithm Methodology

Specialized algorithm knowledge used by the sns-strategist and visual-planner agents when designing content strategy and visuals.

Why Understanding Algorithms Matters

Even great content can be shown to only 10% of followers by the algorithm. The algorithm is not the enemy — it is a tool to be leveraged.
