What it does
Agent Prompt is an agent skill from getsentry/warden, published by the product's own GitHub organization. Reference guide for writing effective agent prompts and skills. Use when creating new skills, reviewing prompt quality, or understanding Warden's prompt architecture.
Its SKILL.md is about 430 tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including reference files (for example `references/agentic-patterns.md`, `references/anti-patterns.md` and `references/context-design.md`).
The repository describes itself as: Your code is under new management. Agents that review your code.
When your agent uses it
- Creating new skills
- Reviewing prompt quality
- Understanding Wardens prompt architecture
Example prompts
- “/agent-prompt”
Requirements
- Pre-approved tools (allowed-tools): Read, Grep, Glob
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Read relevant reference documents before answering
- Provide specific, actionable guidance
- Show examples from existing Warden skills when helpful
- Cite sources (Anthropic docs, etc.) for best practices
What it can do on your machine
Read from SKILL.md and the folder at commit 1ee135e. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
ReadGrepGlob
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
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
Agent Prompt loads about 430 tokens when it runs, and up to ~6.3k if it reads all its reference files. Until then it costs about 45 tokens; SKILL.md has 126 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 126 words (~430 tokens).
