What it does
Opentraces Skill Verifier is an agent skill from JayFarei/opentraces. Author a trace-grounded, CALIBRATED verifier for one skill, two ways: an interactive ALIGNMENT SESSION (manual) or AUTOVERIFY (the agent self-aligns to the skill's goal). Use this skill when asked to build, align, calibrate, or autoverify a verifier/rubric for a skill. The agent proposes a rubric; the factory scores it against evidence + labels; a human approves promotion.
Its SKILL.md is about 1.6k 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 Education, covering Quizzes and assessments. It works with Git. The repository describes itself as: A local-first evidence layer for agent work, capturing what the agent sees, does, and changes.
When your agent uses it
- Autoverify a verifier/rubric for a skill
- Tasks that involve Quizzes and assessments
Example prompts
- “/opentraces-skill-verifier”
Workflow steps
8 steps, taken from the first numbered list in SKILL.md.
- ORIENT — read_skill_definition(skill): read the TARGET skill's goal. In MANUAL mode,
- list_candidates(skill) — evidence + which markers are deficient + calibration
- get_skill_examples(skill, episodes=...) — real example vs counterexample trace refs.
- Author the rubric
- Judge the semantic criteria (agent): for each agent criterion × trace,
- Label (manual): record_human_label(package_dir, ..., label=0|1, human_confirm=True) —
- calibrate_rubric(rubric, episodes=...) — per-criterion precision/recall/discrimination,
- score_rubric / present for approval — only on calibrated/provisional. The headline
What it can do on your machine
Read from SKILL.md and the folder at commit 354755d. 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.
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
Opentraces Skill Verifier loads about 1.6k tokens when it runs. Until then it costs about 100 tokens; SKILL.md has 778 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 778 words (~1,650 tokens).
“A skill verifier is a calibrated rubric, not a checklist. The reframe that governs everything here:”
