skill-contract-reviewerValidates an Agent Skill package against a portable contract with a Python checker, then picks the smallest set of instruction, capability or lifecycle primitives for the task.
Use this skill when a workflow is about to become a reusable agent artifact. The agent sets SKILL_ROOT to the installed skill's directory and TARGET_ROOT to the original workspace, resolves the proposed skill under it, and reads references/contract.md to validate the portable SKILL.md identity fields. It then reads references/decision-model.md to separate repository context, reusable method, external capability, lifecycle timing, deterministic logic and isolated delegation.
Before running anything it shows the exact resolved argument vector, then runs scripts/check_skill.py on the target skill and inspects the JSON report, fixing every error before discussing host-specific extensions. It compares the proposed artifact with assets/task-shapes.json and returns the smallest composable set of primitives. The output is the validation report, the selected primitives with one sentence of reasoning each, and execution evidence: script path, target path, working directory, argv and exit code, with anything the host cannot show marked unverified.
Two guardrails apply: runtime extensions must not be presented as part of the portable contract, and a valid skill is not permission to run scripts or access tools.
7 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 56c886c. It shows what the files ask for, not the result of running them.
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.
Ships 1 file in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Skill Contract Reviewer loads about 450 tokens when it runs, and up to ~975 if it reads all its reference files. Until then it costs about 37 tokens; SKILL.md has 208 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.
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); the scripts in this folder are not scanned.

Skill Contract Reviewer fits situations like: checking that a new SKILL.md package meets the portable skill contract; deciding whether a workflow should be a skill, a tool or a hook; reviewing a skill before publishing it.
Run `npx skills add rohitg00/ai-engineering-from-scratch --skill skill-contract-reviewer -a claude-code`. Or copy the skill folder (phases/13-tools-and-protocols/22-skills-and-agent-sdks/outputs/skill-contract-reviewer in rohitg00/ai-engineering-from-scratch) into .claude/skills/skill-contract-reviewer in your project. Claude Code loads it when a task matches its description.
Run `npx skills add rohitg00/ai-engineering-from-scratch --skill skill-contract-reviewer -a codex`. Or copy the skill folder (phases/13-tools-and-protocols/22-skills-and-agent-sdks/outputs/skill-contract-reviewer in rohitg00/ai-engineering-from-scratch) into .agents/skills/skill-contract-reviewer in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add rohitg00/ai-engineering-from-scratch --skill skill-contract-reviewer -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/skill-contract-reviewer, .gemini/skills/skill-contract-reviewer, .github/skills/skill-contract-reviewer and .opencode/skills/skill-contract-reviewer in your project.
Going by SKILL.md and its folder, Skill Contract Reviewer needs Python for the scripts in its folder and the command-line tools its instructions call (python3). Our summary lists: Python 3, for scripts/check_skill.py.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
Skill Contract Reviewer is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 450 tokens (SKILL.md is roughly 1.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 525 tokens, read only when the agent opens those files.
