What it does
Alt Text is an agent skill from bholmesdev/skills. Write concise alt text for a local image file. Use this when the user asks for alt text, accessibility text, or a brief image description for a specific local image path. Pass the target image path as $0.

It sits in Frontend & Design. The licence is MIT.
When your agent uses it
- Asks for alt text
- Accessibility text
- A brief image description for a specific local image path
Example prompts
- “/alt-text”
What it can do on your machine
Read from SKILL.md and the folder at commit 44da67b. 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
Alt Text loads about 261 tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 128 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
