Skills - Private Gpt

A skill is a packaged set of instructions — defined by a SKILL.md file — that can be attached to a model request. Skills let you build reusable personas, workflows, or domain-specific assistants without repeating system prompts.

Skills are versioned. You can update a skill without breaking existing integrations that pin to an older version.

Create a skill

bash

curl -X POST http://localhost:8080/v1/skills \
  -F 'display_title=Legal Reviewer' \
  -F 'collection=my-org' \
  -F 'skill_md=# Legal Reviewer\n\nYou are a legal document reviewer. Always flag missing clauses and ambiguous language.'

Key fields:

Field	Description
`display_title`	Human-readable name
`collection`	Scope — usually an org or workspace identifier
`skill_md`	Inline `SKILL.md` content
`loading`	`lazy` (default) or `eager` — when instructions are injected

List skills

bash

curl "http://localhost:8080/v1/skills?collection=my-org"

Get a skill

bash

curl "http://localhost:8080/v1/skills/skill_01abc...?collection=my-org"

Update

Skills are immutable once created. Add a new version instead of editing:

bash

curl -X POST http://localhost:8080/v1/skills/skill_01abc.../versions \
  -H "Content-Type: application/json" \
  -d '{
    "skill_md": "# Legal Reviewer v2\n\nUpdated instructions..."
  }'

List versions:

bash

curl http://localhost:8080/v1/skills/skill_01abc.../versions

Delete a skill

bash

curl -X DELETE "http://localhost:8080/v1/skills/skill_01abc...?collection=my-org"

Read-only skills (source anthropic or zylon) cannot be deleted.
