| description | Measure Z3 performance on a formula or file. Collects wall-clock time, theory solver statistics, memory usage, and conflict counts. Results are logged to z3agent.db for longitudinal tracking. |
Given an SMT-LIB2 formula or file, run Z3 with statistics enabled and report performance characteristics. This is useful for identifying performance regressions, comparing tactic strategies, and profiling theory solver workload distribution.
Action:
Invoke benchmark.py with the formula or file. Use --runs N for
repeated timing.
Expectation:
The script invokes z3 -st, parses the statistics block, and prints
a performance summary. A run entry is logged to z3agent.db.
Result: Timing and statistics are displayed. Proceed to Step 2 to interpret.
python3 scripts/benchmark.py --file problem.smt2
python3 scripts/benchmark.py --file problem.smt2 --runs 5
python3 scripts/benchmark.py --formula "(declare-const x Int)..." --debug
Action: Review wall-clock time, memory usage, conflict counts, and per-theory breakdowns.
Expectation: A complete performance profile including min/median/max timing when multiple runs are requested.
Result: If performance is acceptable, no action needed. If slow, try simplify to reduce the formula or adjust tactic strategies.
The output includes:
With --runs N, the script runs Z3 N times and reports min/median/max timing.
Action: Query past benchmark runs from z3agent.db to detect regressions or improvements.
Expectation: Historical run data is available for comparison, ordered by recency.
Result: If performance regressed, investigate recent formula or tactic changes. If improved, record the successful configuration.

Conversational skill that interviews users to design new agentic workflows
Route gh-aw workflow design/create/debug/upgrade requests to the right prompts.
Run AddressSanitizer and UndefinedBehaviorSanitizer on the Z3 test suite to detect memory errors, undefined behavior, and leaks. Logs each finding to z3agent.db.
Run Clang Static Analyzer (scan-build) on Z3 source and log structured findings to z3agent.db.
Translate constraint problems into SMT-LIB2 or Z3 Python API code. Handles common problem classes including scheduling, graph coloring, arithmetic puzzles, and verification conditions.
Parse and interpret Z3 output for human consumption. Handles models, unsat cores, proofs, statistics, and error messages. Translates solver internals into plain-language explanations.
