What it does
Condition Based Waiting is an agent skill from sandgardenhq/sgai. Use when tests have race conditions, timing dependencies, or inconsistent pass/fail behavior - replaces arbitrary timeouts with condition polling to wait for actual state changes, eliminating flaky tests from timing guesses
Its SKILL.md is about 930 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 Testing & QA, covering Async programming and Failing and flaky tests. The repository describes itself as: Sandgarden AI Software Factory.
When your agent uses it
- Tests have race conditions
- Timing dependencies
- Inconsistent pass/fail behavior - replaces arbitrary timeouts with condition polling to wait for actual state changes
- Eliminating flaky tests from timing guesses
Example prompts
- “/condition-based-waiting”
Workflow steps
3 steps, taken from the first numbered list in SKILL.md.
- First wait for triggering condition
- Based on known timing (not guessing)
- Comment explaining WHY
What it can do on your machine
Read from SKILL.md and the folder at commit 9efbb7b. 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 (its code samples are typescript and dot).
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
Condition Based Waiting loads about 933 tokens when it runs. Until then it costs about 62 tokens; SKILL.md has 241 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 241 words (~933 tokens).
“Flaky tests often guess at timing with arbitrary delays. This creates race conditions where tests pass on fast machines but fail under load or in CI.”
