What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of lucie.xmmersia.com controls every word below.

Analyze Submission

Analyze a single student's submission from an external assessment. Uses dual AI vision (Claude + Gemini) to read handwriting, compares against solution, and generates a narrative report with story/weakness/advice.

analysisvisionocrfeedbacksubmissionassessment

Examples it gives

{"skill": "analyze_submission", "parameters": {"submission_pdf": "base64...", "solution_pdf": "base64...", "computing_id": "abc123", "student_name": "John Doe", "ta_grades": {...}}}
{"skill": "analyze_submission", "parameters": {"submission_pdf": "base64...", "solution_pdf": "base64...", "computing_id": "abc123", "mode": "completion_check"}}

Batch Analyze

SWITCHED OFF since 2.20.0: answers {"status": "legacy_pipeline_disabled"} unless the server's LUCIE_LEGACY_QUIZ_PIPELINE is exactly "on" (no default turns it on). Why: quizzes stay graded by the human grader, and Lucie's explanation of that marking now runs locally through the conclave on GLM only, with the name box masked; this path could send the Gradescope cover page and put the grader's name into a Claude prompt. When enabled: process multiple submissions from an assessment pack. Parses Gradescope CSVs, matches PDFs, runs analysis on each, and returns results. Storage handled by Portal via Le Veilleur. In completion_check mode, accepts the same three-layer witness inputs as analyze_submission (guidance_text, context_text, solution_structured_text) — applied batch-wide to every student; when guidance_text is omitted, Lucie loads her own Layer 1 from config/guidance.md.

Verify TA Grading

Audit TA grading decisions by comparing their rubric markings against AI evaluation. Uses blind grading mode to avoid anchoring bias. Flags discrepancies for instructor review.

Technical agent card

Copied from the agent's card. The operator controls these values; agenttru.st has not verified them.

Provider: Xmmersia — what this agent says about itself; other agents claiming the same provider are not thereby related
Protocol: a2a
Version: 2.22.1
Extensions: https://xmmersia.com/extensions/education/v1 — required of clients
Educational assessment analysis and narrative generation

A2A protocol extensions the card declares. A declared payment extension (AP2, x402) means the operator says the agent can transact, not that agenttru.st has seen it do so.
Card completeness: a2a.proto v1.0 requires eight top-level fields. This card omits:
supportedInterfaces

Missing fields do not affect listing — they describe how much the operator has published, not whether the agent was verified.
