Exact prompt

This is a sandboxed mock job portal. resume.json is the candidate. forms/ has two job application forms (field definitions). For each form, write a JSON file {"job_id": ..., "answers": {field_name: value}} filled truthfully from the resume (never invent facts), then submit it with: python3 submit.py <file>. Fix and resubmit if rejected. Both applications must end up SUBMITTED.

Task prompt given to the agent (headless, offline, synthetic fixture inputs): This is a sandboxed mock job portal. resume.json is the candidate. forms/ has two job application forms (field definitions). For each form, write a JSON file {"job_id": ..., "answers": {field_name: value}} filled truthfully from the resume (never invent facts), then submit it with: python3 submit.py <file>. Fix and resubmit if rejected. Both applications must end up SUBMITTED. Inspired by https://x.com/SAkasxh/status/2104655629021565156 (unverified; not checked with the author). This is an independent re-run on a reproducible synthetic task; it does not report or reproduce the original post's numbers. Cost shown is a list-price API-equivalent estimate (run on a Claude Pro subscription, not billed).

Success criteria: All automated rubric checks pass: ACME submitted; Globex submitted; ACME identity fields match resume; ACME years_experience = 6-9; ACME authorized = yes; ACME skills only from resume; Globex names/title/email match; Globex relocation false; Globex salary = 165000; Globex linkedin from resume (if given).

Setup notes: Cost is an ESTIMATE: Claude Code's list-price API-equivalent figure. The run used a Claude Pro subscription, so nothing was billed. input_tokens = all input incl. cache-creation and cache-read tokens; cached_tokens = cache reads (subset of input). Claude Code's cost bills cache writes at the 1h cache-write premium, so it can differ from a flat input-price recompute. Web disabled; tools Read/Write/Edit/Glob/Grep/Bash; single run; scored automatically (10/10 checks).

Estimated cost List-price estimate; not actually billed.

It counts as a success only if it meets every success criterion: All automated rubric checks pass: ACME submitted; Globex submitted; ACME identity fields match resume; ACME years_experience = 6-9; ACME authorized = yes; ACME skills only from resume; Globex names/title/email match; Globex relocation false; Globex salary = 165000; Globex linkedin from resume (if given).

Seven years of experience falls in the \"6-9\" option.\n- **GLX-77 (Analytics Engineer):** open to relocation is `false`, matching the resume, and desired salary is 165000.\n\nI wrote the \"why Acme\" text and the Globex cover note myself, using only facts from the resume: title, years of experience and skills.
