What it does
Error Resolver is an agent skill from aiskillstore/marketplace. Systematic error diagnosis and resolution using first-principle analysis. Use when encountering any error message, stack trace, or unexpected behavior. Supports replay functionality to record and reuse solutions.
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 17 other files (for example `analysis/root-cause.md`, `analysis/stack-trace.md` and `patterns/database.md`).
It sits in Development, covering GraphQL and Debugging. The repository describes itself as: Security-audited skills for Claude, Codex & Claude Code. One-click install, quality verified.

What it can do on your machine
Read from SKILL.md and the folder at commit ad8daf7. 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
Shell commands in SKILL.md call:
gitnodenpmpippython
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, npm and pip, which can reach the network depending on how they are called.
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
Error Resolver loads about 2k tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 535 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: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteRuns commands with sudoSKILL.md:40
PermissionError | File/directory access, sudo needed |
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
Without a licence we can't republish the file, so here is its outline and opening line. It has 535 words (~2,028 tokens).
“A first-principle approach to diagnosing and resolving errors across all languages and frameworks.”
