paladin-setup

Paladin setup

Create or update PALADIN.md in the current repository.

Setup contract

Collect only the slots required for the selected action.

Slot	Required when	Allowed values or format
target_repo	Always	Current working directory, unless the user names another repo
existing_config	When PALADIN.md exists	Preserve unless the user asks to replace it
paladin_conversion	Always	create_review_task, ask_first, report_only
paladin_action_destination	When conversion is not report_only	one_horizon, linear, jira, email, custom
paladin_custom_action	For linear, jira, email, or custom	One sentence with the exact handoff rule
one_horizon_workspace_id	For One Horizon create or ask flows	Workspace ID from MCP or user input
one_horizon_initiative_id	Optional	Initiative ID to link findings under
one_horizon_team_ids	Optional	YAML array of team IDs
one_horizon_assignee_ids	Optional	YAML array of user IDs
paladin_source_list	Always	Default references/security-sources.md

Decision flow

1. Confirm target_repo.
2. Read PALADIN.md if it exists.
3. If a config already exists, summarize the current action and destination, then ask whether to update it or leave it unchanged.
4. Ask for paladin_conversion when it is missing or the user wants to change it.
5. If conversion is report_only, set paladin_action_destination: custom and paladin_custom_action: "", then skip destination setup.
6. If conversion is create_review_task or ask_first, ask for paladin_action_destination.
7. If the destination is one_horizon, run the One Horizon MCP check.
8. If the destination is linear, jira, email, or custom, ask for paladin_custom_action.
9. Ensure the source list path exists or record it under Still needed.
10. Write or update PALADIN.md.
11. Re-read PALADIN.md and validate the frontmatter.

Ask one question at a time. Do not ask for slots that are not needed for the selected action.

Question order

Use these questions when the answer is not already known from the request or existing config:

Which repo should I configure? I am currently in {cwd}.

After Paladin finds security work, should it create an item automatically, ask first, or only report?

Where should the item go: One Horizon, Linear, Jira, email, or a custom workflow?

What exact handoff should Paladin prepare for {destination}?

Defaults

• Default paladin_conversion to create_review_task only when the user wants setup and does not choose another action.
• Default paladin_action_destination to one_horizon only when conversion is create_review_task or ask_first.
• Default paladin_source_list to references/security-sources.md.
• Default team and assignee arrays to [].
• Leave optional IDs blank when unknown.
• Do not invent workspace, initiative, team, assignee, Linear, Jira, or email values.

One Horizon MCP check

When the selected destination is One Horizon:

1. Check whether One Horizon MCP tools are available in the current tool list. Common tool namespaces include mcp__onehorizon__ and mcp__codex_apps__one_horizon__.
2. If available, call a lightweight identity or workspace check such as who_am_i or list_workspaces.
3. If the check succeeds:
   • use the existing one_horizon_workspace_id when present
   • use the default workspace only when exactly one clear default is returned
   • otherwise ask which workspace ID to use
   • ask for an initiative ID only if the user wants findings linked to an initiative
   • use empty arrays for teams and assignees unless the user provides IDs
4. If One Horizon tools are missing or auth fails, ask exactly:

One Horizon is not configured in this session. Do you want to configure it now, choose another destination, or use report_only?

If the user wants to configure One Horizon now, explain that the One Horizon MCP/app connector must be enabled in the current agent environment. Do not fabricate MCP settings.

If the user does not want to configure One Horizon now, do not block setup. Write PALADIN.md with the destination and action they choose.

PALADIN.md frontmatter

Keep frontmatter keys in this order:

---
paladin_conversion: {paladin_conversion}
paladin_action_destination: {paladin_action_destination}
paladin_custom_action: "{paladin_custom_action}"
paladin_source_list: {paladin_source_list}
one_horizon_workspace_id: "{one_horizon_workspace_id}"
one_horizon_initiative_id: "{one_horizon_initiative_id}"
one_horizon_team_ids: []
one_horizon_assignee_ids: []
---

For report_only, use:

paladin_conversion: report_only
paladin_action_destination: custom
paladin_custom_action: ""

Write rules

• Preserve existing non-frontmatter body text when updating PALADIN.md unless the user asks to replace it.
• If PALADIN.md has YAML frontmatter, update only the Paladin keys unless the user asks for a rewrite.
• If PALADIN.md has no YAML frontmatter, add the Paladin frontmatter at the top and preserve the body below it.
• If creating a new file, add this short body:

# Paladin configuration

This file controls what Paladin does after it finds security work in this repo.

• Use repo-root references/security-sources.md as the canonical source list.
• If references/security-sources.md is missing in the target repo, locate the bundled Paladin source list by walking up from the current skill folder until both plugin.json and references/security-sources.md exist, then copy that file into the target repo. This is the only extra file setup should create.
• Do not use parent-directory fallback paths from an individual skill folder; they resolve differently across .agents, .claude, and plugin installs.
• If the source list cannot be created, still write PALADIN.md and include the missing source list in Still needed.
• If the selected destination tool is unavailable, still create PALADIN.md and state what remains to configure.

Validation

After writing, re-read PALADIN.md and verify:

• all required frontmatter keys are present
• paladin_conversion is one of create_review_task, ask_first, or report_only
• paladin_action_destination is one of one_horizon, linear, jira, email, or custom
• paladin_custom_action is present for linear, jira, email, and custom when conversion is not report_only
• one_horizon_workspace_id is present for One Horizon create or ask flows, or listed under Still needed
• the configured source list exists, or is listed under Still needed
