An AI agent reads the role against my record and says where I fit, with evidence, and where I don’t. Nothing runs until you press the button.
How this worksexpandcollapse
- Model
- Claude Haiku 4.5 (
claude-haiku-4-5), called only from the server. Nothing runs until you press the button. - Source
- It answers only from a fixed file of 53 facts, which you canread in full, gaps included. Up to 15,000 characters are used; longer text is trimmed, not refused. Equal opportunity statements, privacy notices, cookie text and application form fields are removed before the model sees it. Your text is treated as an untrusted description of a role, and any instructions in it are ignored.
- Second check
- Rules in code drop any claim that cites no fact, cites a fact that doesn’t exist, runs too long, or uses a number its facts don’t contain. Then a second model call checks each remaining claim against only the facts it cites and removes anything it can’t trace.
- Limits
- 5 runs per visitor per day. The agent stops for the day once estimated spend reaches$2.
- Failure
- If the model is slow, fails, or its answer doesn’t survive the checks, you get a short static summary instead. Nothing else on this site depends on the agent.
- Tested
- Across the last 3 full runs of the evaluation set (5 October 2026), 79 / 84 cases passed, with no invented facts in any of them. The cases include roles I fit, roles I don’t, text that isn’t a job description and prompt-injection attempts.
The agent isn’t available right now, so here’s the short version.static
