SpecAgent generates and refines ACSL specifications for C programs, using dependency-aware planning, verification feedback to repair earlier specifications, and critique to detect contracts that pass proof but remain weak. On 50 programs from 14 repositories, it achieved 96.82% precision and 88.95% recall; it also discharged 604 of 811 verification targets, not entire programs. Results concern C with Frama-C/WP.
