What it does
Spec Optimizer is an agent skill from cdavid817/vanehub-ai. Analyze and safely optimize OpenSpec main specifications. Use when asked to find semantically duplicate Requirements or Scenarios, cluster related capabilities, enforce spec line/token budgets, or generate reviewable consolidation mappings and diffs without changing main specs automatically.
Its SKILL.md is about 350 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).
It sits in AI & LLM Engineering, covering LLM cost and token optimization. It works with Google Gemini, React, Tauri and TypeScript. The repository describes itself as: AI 编程智能体统一桌面工作台 | Desktop hub for managing Claude Code, Codex CLI, Gemini CLI & OpenCode. Tauri 2 · Rust · React · SQLite. The licence is Apache-2.0.
When your agent uses it
- Asked to find semantically duplicate Requirements
- Cluster related capabilities
- Enforce spec line/token budgets
- Generate reviewable consolidation mappings and diffs without changing main specs automatically
Example prompts
- “/spec-optimizer”
Workflow steps
7 steps, taken from the first numbered list in SKILL.md.
- Parse capability, Requirement, Scenario, SHALL, and MUST units.
- Report duplicate candidates and capability clusters as recommendations, not facts.
- Flag specs above 500 lines or 8,000 tokens unless the user supplies different budgets.
- For every proposed merge, create a mapping from each source Requirement and Scenario to a retained target or an explicit rejection reason.
- Fail the coverage check when any source SHALL or MUST is missing from the mapping.
- Write review artifacts in a new OpenSpec change: analysis/report.md, analysis/mapping.md, analysis/coverage.md, analysis/diff.md, and…
- Stop before applying changes. Ask the user to review the artifacts and use the normal OpenSpec workflow for approved edits.
What it can do on your machine
Read from SKILL.md and the folder at commit 41ab955. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Spec Optimizer loads about 347 tokens when it runs. Until then it costs about 77 tokens; SKILL.md has 146 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
