What it does

Complexity Detection is an agent skill from hashgraph-online/awesome-codex-plugins. Classify a task or feature as quick, standard, or thorough so the rest of the pipeline (budget sizing, model routing, review depth) can right-size itself. Used by /ck:sketch to default the kit's complexity, by /ck:map to assign task depth, and by /ck:make for per-task budgets. Also invoked by the ck:complexity agent with the haiku model. Trigger phrases: "how complex", "what depth", "pick a depth", "classify this task".

Its SKILL.md is about 1k 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 AI & LLM Engineering, covering Model routing and gateways. The repository describes itself as: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is Apache-2.0.

When your agent uses it

  • Phrases: how complex
  • Classify this task

Example prompts

  • “how complex”
  • “what depth”
  • “pick a depth”
  • “/complexity-detection”

What it can do on your machine

Read from SKILL.md and the folder at commit 16b4156. 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 (its code samples are json).

    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

Complexity Detection loads about 1k tokens when it runs. Until then it costs about 111 tokens; SKILL.md has 356 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~111
When it runs · the whole SKILL.md, loaded when a task matches
~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.

Complexity Detection

A deterministic scoring rubric. Five axes, 0–4 each, summed to 0–20.

Total score maps to:

Override signals

Upgrade one step regardless of score when any of these are true:

  • Security-sensitive: authentication, authorization, crypto, secrets, PII.
  • Data migration that is not reversible.
  • Public API shape change (breaking).
  • Performance-critical hot path with an existing SLA.

Downgrade one step only when all of these are true:

  • Zero new dependencies.
  • Existing tests cover the change.
  • No user-visible behaviour change.
  • Single file, single function.

How agents score

The ck:complexity subagent (haiku) receives a task description and returns a JSON blob:

json
{
  "score": 11,
  "depth": "standard",
  "axes": {
    "files": 2, "type": 2, "judgment": 2, "cross_component": 2, "novelty": 3
  },
  "overrides_applied": []
}

/ck:map calls this agent per task to set depth in the task registry. If the agent produces a score in the "thorough" band with a novelty of 4 and a security override, it may return needs_research: true, which /ck:map must translate into an upstream ck:researcher task dependency before the work itself.

Integration points

  • /ck:sketch — runs complexity scoring on the whole domain to set the kit's complexity: frontmatter.
  • /ck:map — runs it per task to assign depth.
  • /ck:make — reads depth to size the task budget and pick the review intensity.
  • ck:complexity agent — pure-haiku worker; does nothing else.

Anti-patterns

  • Using one depth for every task in a kit "for consistency." Cost up, signal down.
  • Padding depth to "be safe" — if the budget is oversized, the model wastes tokens exploring. Right-size, then raise only when verification fails.
  • Ignoring overrides — scoring a login flow as "quick" because it touches one file. Security overrides exist for exactly this reason.

Or copy the skill folder (plugins/JuliusBrussee/blueprint/skills/complexity-detection in hashgraph-online/awesome-codex-plugins) into .agents/skills/complexity-detection in your project. Codex loads it when a task matches its description.

Can I use Complexity Detection in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add hashgraph-online/awesome-codex-plugins --skill complexity-detection -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/complexity-detection, .gemini/skills/complexity-detection, .github/skills/complexity-detection and .opencode/skills/complexity-detection in your project.

What does Complexity Detection need to run?

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

Does Complexity Detection 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.
