What it does
Vibeguard is an agent skill from majiayu000/spellbook. Lightweight anti-hallucination workflow for task kickoff, review prioritization, and regression retrospectives. Use when the user asks for guardrails, task contracts, risk scoring, or review templates.
Its SKILL.md is about 720 tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/review-template.md`, `references/scoring-matrix.md` and `references/task-contract.yaml`).
It sits in Product & Project Management, covering Prioritization frameworks, Retrospectives and LLM guardrails. The repository describes itself as: Cross-runtime skills for Claude Code, Codex, and multi-agent workflows. The licence is MIT.
When your agent uses it
- The user asks for guardrails
- Review templates
Example prompts
- “/vibeguard”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit ed52af7. 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
Vibeguard loads about 723 tokens when it runs, and up to ~1.9k if it reads all its reference files. Until then it costs about 53 tokens; SKILL.md has 310 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.

VibeGuard
Lightweight VibeGuard for everyday use inside Spellbook.
This skill helps with three moments where AI-assisted work usually drifts:
- before implementation starts
- while review findings are being prioritized
- after regressions or avoidable mistakes happen
What This Skill Includes
- A task contract checklist for scoping work before coding
- A scoring matrix for prioritizing findings with evidence
- A weekly review template for regression and guardrail retrospectives
Hard Boundaries
This skill is intentionally lightweight.
It does:
- guide task kickoff
- structure review output
- make risk tradeoffs explicit
It does not:
- install hooks
- run guard scripts automatically
- patch global Claude or Codex configuration
- claim that full VibeGuard enforcement is active
If the user asks for automated interception, repo-level rules, or environment setup, escalate to the full VibeGuard repository and tooling.
When To Use It
Trigger this skill when the user asks for:
- anti-hallucination guardrails
- task startup checks
- review scoring or triage
- regression prevention
- retrospective templates
- "vibeguard" by name
Workflow
1. Start With The Task Contract
Open references/task-contract.yaml and confirm:
- goal
- source of truth
- acceptance criteria
- scope
Do not move into implementation until these are concrete.
2. Score Findings Before Acting
Open references/scoring-matrix.md and score each finding on:
- impact
- effort
- risk
- confidence
Use the score to separate urgent fixes from weak guesses.
3. Pick The Right Delivery Mode
- 1-2 files: implement directly once the contract is clear
- 3-5 files: write a short spec or step plan first
- 6+ files: produce a full design/spec and staged execution plan
4. Review The Failure, Not Just The Symptom
If something regressed, identify which defense failed:
- scope control
- source-of-truth validation
- verification depth
- review prioritization
- missing guardrail
Then capture the follow-up in references/review-template.md.
Expected Outputs
Depending on the request, produce one of these:
- a filled task contract
- a scored findings table with priorities
- a short regression review or weekly retrospective
