At a glance

What it does
Debugging Runtime Errors is an agent skill from friday-platform/friday-studio. Loads when a session ends with status: failed AND a structured error message. Recognize: did not call complete (agent never called the injected complete tool); emitted empty output (called complete with {}); emitted an empty response (called complete with empty string); LLM step failed: (agent called failStep); output does not match schema (outputType validation failed); Invalid job config / Invalid signal config (Zod schema rejection on upsert). Each pattern has a one-line fix in the table below.
Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development, covering Debugging. It works with Zod. The repository describes itself as: Agent Harness Platform — shareable workspaces, MCP tools, skills, memory, and cron/webhook automations. Self-hosted and transparent.
When your agent uses it
- Tasks that involve Debugging
Example prompts
- “Use the debugging-runtime-errors skill to load when a session ends with status: failed AND a structured error message”
- “/debugging-runtime-errors”
What it can do on your machine
Read from SKILL.md and the folder at commit fb3069a. 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
Debugging Runtime Errors loads about 1k tokens when it runs. Until then it costs about 136 tokens; SKILL.md has 449 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 449 words (~1,040 tokens).
“When a session emits status: failed with a specific error message, the message itself names the contract violation. This skill maps each error pattern to its fix.”
