complexity-grill

complexity-grill is a skill for Claude Code, Codex from OutlineDriven/odin-claude-plugin. It costs 47 tokens per session (639 once invoked), scanned A, a copy of complexity-grill, Apache-2.0.

A read-only code analysis that identifies and ranks the main sources of complexity in a chosen part of a codebase before counting metrics. It looks at issues such as coupling, hidden state, leaky abstractions, and too many special cases.

In plain words
What is it for?
Use it to examine a module, design, or code region and decide which complexity problems should be addressed first.
Why use it?
A complexity score can show that code is difficult without explaining why. This produces a qualitative explanation of the root causes first.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

complexity-grill scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Complexity grill

Contract

Field Bound contract
Trigger User wants to identify the true sources of complexity qualitatively before counting metrics.
Authority Read-only. No file, VCS, credential, paid, published, deployed, or remote mutation.
Side effect Chat output only: a qualitative complexity-source report with ranked root causes.
Done True complexity sources are identified qualitatively and ranked before any metric is counted.

Inputs

The code region, module, or design surface to analyze must be supplied. Optional: a named concern to weight (coupling, hidden state, leaky abstraction, special-case proliferation, accidental concurrency, premature generality, indirection exceeding what it hides). No metric input is accepted before the qualitative ranking is settled.

Procedure

  1. Bound scope to the named region and read it. Do not mutate anything. Done when: the region is read and scope is bounded.
  2. Enumerate candidate complexity sources qualitatively. For each, state where it lives and what effort it forces: coupling that blocks independent change, hidden state that must be tracked by hand, leaky abstractions, special-case proliferation, accidental concurrency, premature generality, or indirection that exceeds the complexity it hides. Done when: every candidate source is named with its location and forced effort.
  3. Rank candidates by the real cognitive or maintenance effort they force, not by any numeric metric. Break ties by root cause: a source that produces other sources ranks above a symptom it creates. Done when: candidates are ranked by effort with root-cause tie-breaking.
  4. Only after the qualitative ranking is settled, optionally attach a metric to confirm a ranked source. Metrics confirm; they never discover, reorder, or lead the ranking. If no metric is available, the ranking stands on its qualitative evidence. Done when: a metric is attached as confirmation or the ranking stands on qualitative evidence alone.
  5. Return the ranked report. Done when: the ranked report is returned.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

complexity-grill is a skill published in the GitHub repository OutlineDriven/odin-claude-plugin (35 stars, last pushed yesterday), licensed Apache-2.0. It adds 47 tokens to every session and 639 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to complexity-grill, differing in 2 lines, and is treated as a copy.
