Incrementally evolve and verify an existing Specula TLA+ suite for a new source revision. Use when an Agent has a prior Specula run plus old and new source, and must decide whether the model changes, update the reference/MC/Trace suite, generate Update.tla, reuse and rebase the prior trace harness for update-focused validation, model-check changed/unchanged interactions, and hand real counterexamples to bug reproduction.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'incremental-modeling' ] || [ -L ~/.agents/skills/'incremental-modeling' ]; then echo 'A skill folder named incremental-modeling already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/specula-org/Specula' "$d" && git -C "$d" checkout --quiet 'e616bdae7b4eea622f8248ead79b9f8937c29fe7' -- 'skills/incremental-modeling' && mkdir -p ~/.agents/skills && cp -R "$d"/'skills/incremental-modeling' ~/.agents/skills/'incremental-modeling' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'incremental-modeling' ~/.claude/skills/'incremental-modeling' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
