What it does

Iterations is an agent skill from real-simple-labs/parker-brain. The full iteration flow in one skill — choose which ads to iterate on, then make the iterations. If the user names a specific ad, go straight to making iterations; if they ask account-level (which ads should we iterate on, what to iterate this month), select the ads first, then make iterations on each.

Its SKILL.md is about 5.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files (for example `processes/INDEX.md`, `processes/audience-iteration.md` and `processes/creator-reshoot-same-script.md`).

Example prompts

  • “/iterations”

Workflow steps

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

  1. Load brand context — strategy first. The brand's committed strategy (strategy/ — the working thesis and roadmap) frames which ads are…
  2. Pull the account, sorted by spend. Top-spending ads over a 60-day window with spend, week-over-week spend trend, run time, and core…
  3. Read each candidate against the selection method. Is spend significant in the context of this account's scale? Is it rising, steady, or…
  4. Read the 60-day account trends. What the top performers share (formats, angles, creators, emotions, a-roll vs b-roll, how soon the product…
  5. Present the ranked shortlist and checkpoint. The ads to iterate on, in priority order, each with the spend/trend/run-time/promo read and…
  6. Proceed to Phase B on each confirmed ad, carrying its selection reasoning forward.

What it can do on your machine

Read from SKILL.md and the folder at commit 2a6f6c6. 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

Iterations loads about 5.1k tokens when it runs. Until then it costs about 79 tokens; SKILL.md has 2,901 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~79
When it runs · the whole SKILL.md, loaded when a task matches
~5.1k

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

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,901 words (~5,057 tokens).

“Take a performing ad and recommend the highest-confidence iterations to extend its life with the audience that already responds, or unlock new audiences with the same proven message. This skill owns the whole flow in two phases:”

With the skills CLI, run `npx skills add real-simple-labs/parker-brain --skill iterations -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/iterations, .gemini/skills/iterations, .github/skills/iterations and .opencode/skills/iterations in your project.

What does Iterations need to run?

SKILL.md names no scripts, command-line tools or credentials: Iterations is instructions for the agent only.

Does Iterations access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Iterations safe to install?

How many tokens does Iterations use?

About 5.1k tokens (SKILL.md is roughly 20k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
