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
- Bound scope to the named region and read it. Do not mutate anything. Done when: the region is read and scope is bounded.
- 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.
- 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.
- 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.
- Return the ranked report. Done when: the ranked report is returned.
Failure and recovery
- Metrics-first: if a numeric metric is introduced before the ranking is settled, discard it, return to step 2, and re-rank qualitatively.
- Symptom-as-root: if a ranked source is itself produced by a deeper source, demote it, promote the deeper source, and re-rank.
- Unbounded scope: if the region cannot be read in one pass, narrow to a named sub-region and state the narrowing. Never widen scope to force a result.
- Boundary breach: if any edit or mutation is attempted, stop and report the read-only breach. No partial mutation is retained.
Output
Ranked complexity-source report: ordered root causes, each naming its location, the effort it forces, and whether a deeper source produces it. Any metric appears only as a confirmation footnote after the ranking.
