Code Review Pipeline Setup#

Deploy 3 agents that scan PRs, analyze code quality, and report review results.

Roles#

RoleHostnameSkillsPurposescanner<prefix>-scannerpilot-github-bridge, pilot-task-router, pilot-metricsRuns static analysis and security scans on PRsreviewer<prefix>-reviewerpilot-event-filter, pilot-alert, pilot-audit-logAnalyzes scan results, suggests improvementsreporter<prefix>-reporterpilot-webhook-bridge, pilot-slack-bridge, pilot-receiptPosts PR comments, sends notifications

Setup Procedure#

Step 1: Ask the user which role this agent should play and what prefix to use.

Step 2: Install the skills for the chosen role:

bash

# For scanner:
clawhub install pilot-github-bridge pilot-task-router pilot-metrics

# For reviewer:
clawhub install pilot-event-filter pilot-alert pilot-audit-log

# For reporter:
clawhub install pilot-webhook-bridge pilot-slack-bridge pilot-receipt

Step 3: Set the hostname:

bash

pilotctl --json set-hostname <prefix>-<role>

Step 4: Write the setup manifest:

bash

mkdir -p ~/.pilot/setups
cat > ~/.pilot/setups/code-review-pipeline.json << 'MANIFEST'
{
  "setup": "code-review-pipeline",
  "setup_name": "Code Review Pipeline",
  "role": "<ROLE_ID>",
  "role_name": "<ROLE_NAME>",
  "hostname": "<prefix>-<role>",
  "description": "<ROLE_DESCRIPTION>",
  "skills": { "<skill>": "<contextual description>" },
  "peers": [ { "role": "...", "hostname": "...", "description": "..." } ],
  "data_flows": [ { "direction": "send|receive", "peer": "...", "port": 1002, "topic": "...", "description": "..." } ],
  "handshakes_needed": [ "<peer-hostname>" ]
}
MANIFEST

Step 5: Tell the user to initiate handshakes with direct communication peers.

Data Flows#

• scanner -> reviewer : scan-result events (port 1002)
• reviewer -> reporter : review-verdict events (port 1002)
• reporter -> external : review-notification via webhook (port 443)

Handshakes#

bash

# scanner and reviewer handshake with each other:
pilotctl --json handshake <prefix>-reviewer "setup: code-review-pipeline"
pilotctl --json handshake <prefix>-scanner "setup: code-review-pipeline"

# reviewer and reporter handshake with each other:
pilotctl --json handshake <prefix>-reporter "setup: code-review-pipeline"
pilotctl --json handshake <prefix>-reviewer "setup: code-review-pipeline"

Workflow Example#

bash

# On reviewer — subscribe to scan results:
pilotctl --json subscribe <prefix>-scanner scan-result

# On reporter — subscribe to review verdicts:
pilotctl --json subscribe <prefix>-reviewer review-verdict

# On scanner — publish a scan result:
pilotctl --json publish <prefix>-reviewer scan-result '{"pr":142,"repo":"acme/api","findings":[{"file":"auth.go","line":58,"severity":"high","rule":"sql-injection"}]}'

# On reviewer — publish a review verdict:
pilotctl --json publish <prefix>-reporter review-verdict '{"pr":142,"status":"changes_requested","comments":1}'

Dependencies#

Requires pilot-protocol skill, pilotctl binary, clawhub binary, and a running daemon.
