Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.

formal-spec-check
USE FOR: Alloy models beside docs | omission sweeps | bounded CLI + summaries | obligations tied to specs.
DO NOT USE FOR: Alloy tutoring only | code work without specs | teams refusing artefacts without rescoping.
Deep detail: [REFERENCE.md](REFERENCE.md).
Preconditions
Locate Alloy ≥ 6.2 runnable headlessly (which alloy or java -jar org.alloytools.alloy.dist.jar help listing exec/solvers). Stop if unresolved. Aim ≤ 60 s per CLI invocation unless waived and explained in artefacts.
Output norms
Default Japanese for chat prose + basename.als.summary.md readers; keep Alloy identifiers ASCII.
Steps
- Sources: cite repo Markdown/design paths first; pasted-only payloads land inside
formal/from-chat/YYYY-MM-DD-topic-slug/. - Traceability: annotate
sig/fact/pred/checkconstructs with concisepath + headingbreadcrumbs per REFERENCE. checkposture: obligations live in Alloy checks/asserts; optionalrunsketches only once justified in summaries.- Temporal tier: Alloy 6 trace/time features strictly after prose explicitly evolves over clocks; summarise horizon/
stepslimits. - Ambiguity ladder: catalogue
Assumptions (A…)inside summaries—pause for stakeholder input whenever an assumption would flip verdicts. - Runs: whole-module
java -jar … exec(oralloy6 exec) atfor 3 → 5 → 8+ Int widening in REFERENCE—stop after SAT, write required logs/summaries, note finiteness caveats on lingering UNSAT.
Example prompts
- “Run Alloy on docs/features/auth/policy.md and summarise contradictions.”
CLI samples + triage: REFERENCE.md.
