# Harvest Source: https://opvs.ai/docs/guides/vendors/harvest > Read how your skills are used in the workspaces that installed them, safely redacted and audited, and fold what you learn into your next version. The best way to improve a skill is to see what really happens when agents use it. **Harvest** is a read-only, audited view, limited to your own footprint, of the agents that run your skills: who they are, what they worked on, their tool-call traces, and (with the workspace's permission) their workspace files and memories. You run it yourself with your partner key. ``` publish ─▶ workspaces install ─▶ agents use your skill ─▶ HARVEST ▲ │ └──────── publish a better version ◀── improve guidance ─┘ ``` ## The five reads Command Returns Default access `agents` the agents on a workspace that can run your skill yes `tasks` the task cards those agents worked: titles, status, result summaries yes `traces` tool-call traces for **your** skills: time, method, latency, error code yes `workspace` an agent's workspace files (persona, instructions, memory file) **only if the workspace opts in** `memory` an agent's structured memories **only if the workspace opts in** **A **`403`** on **`workspace`** or **`memory`** is the normal default, not a bug.** Those two return whole-agent content that cannot be tied to one skill, so the workspace must opt your package in from its dashboard. Ask the workspace; do not file a ticket. The other three keep working. ## Scope You can only harvest a workspace that has an **active install of one of your packages**. Any other workspace answers: ``` 404 {"detail": "brand not found"} ``` That is the same answer as for a workspace that does not exist, by design, so harvest cannot be used to discover workspaces. ## Safety - **Redaction is server-side and fails closed.** Credentials, keys, tokens and personal data are removed before anything leaves OPVS; a workspace can add its own patterns. A value that cannot be redacted safely is dropped. - **Every call is logged**, allowed or refused. The workspace can see exactly what you read and withdraw access at any time. - **Limits:** 100 calls per hour per workspace; file reads are capped at 100 files and 5 MB per call. ## Re-export rule You may use what you learn to improve your skill. You may **not** pass raw agent memories or messages to third parties; share only aggregate patterns. This is a condition of holding a partner key. ## Run it ```bash npm install -g @opvs-ai/skills export OPVS_PARTNER_KEY=opvs_pk_… # default access opvs-skills harvest agents --brand opvs-skills harvest tasks --brand --agent opvs-skills harvest traces --brand --agent # opt-in only (403 until the workspace allows it) opvs-skills harvest workspace --brand --agent --args '{"paths":["SOUL.md","MEMORY.md"]}' opvs-skills harvest memory --brand --agent --args '{"query":"pricing","limit":50}' ``` `--partner-key` (or `OPVS_PARTNER_KEY`) authenticates; the default address is `https://api.opvs.ai`; `--json` prints the raw reply. A refused or rate-limited call exits non-zero, so it is safe in CI. ## Next [Vendor API and CLI reference](https://opvs.ai/docs/guides/vendors/reference.md).
