Reduce control-agent SKILL.md from 476 to 303 lines (36%) by: - Deduplicating sentry agent section - Extracting Slack integration details to SLACK.md (progressive disclosure) - Removing health checks section (duplicates HEARTBEAT.md) - Trimming explanations Claude already knows - Replacing placeholder repo names with dynamic lookup Trim dev-agent (225->186) and sentry-agent (121->113) similarly.
Greptile SummaryTrims all three agent SKILL.md files to reduce token usage, following Anthropic's skill authoring best practices (progressive disclosure, removing duplicate content, keeping under 500 lines). The control-agent SKILL.md sees the largest reduction (~36%), extracting Slack integration details into a new

Missing SLACK_BOT_TOKEN env var
sentry_monitor list (still documented in the Tool Reference above) calls the Slack API directly and requires SLACK_BOT_TOKEN. With this env var removed from the documented environment, the agent won't know it's needed and will have no context when list fails with "SLACK_BOT_TOKEN not set." Either re-add SLACK_BOT_TOKEN here or remove list from the Tool Reference if it's not expected to be used by this agent.

Message example omits the SECURITY NOTICE preamble
The actual output from slack-bridge/security.mjs (wrapExternalContent) prepends a multi-line SECURITY NOTICE: block before the <<<EXTERNAL_UNTRUSTED_CONTENT>>> boundary. This example only shows the boundary markers. While the agent can still parse Channel/Thread correctly, the mismatch between the documented format and real messages could cause confusion — especially for an agent encountering the format for the first time via progressive disclosure.
Consider adding the SECURITY NOTICE preamble (even abbreviated) to keep the example faithful to the real format:

Pi agents load SKILL.md as a single document and cannot follow markdown links to separate files. The progressive disclosure pattern doesn't apply here — skills must be self-contained.

Addressed in f4bf919: inlined all Slack content back into SKILL.md and deleted SLACK.md. Pi agents load SKILL.md as a single document and can't follow markdown links to other files — progressive disclosure doesn't apply here. Skills must be self-contained. Control-agent SKILL.md is now 360 lines (down from 476 originally, still a 24% reduction from dedup + trimming). |

| Run `list_sessions` to get live UUIDs, then run: | ||
| ```bash | ||
| bash ~/.pi/agent/skills/control-agent/startup-cleanup.sh UUID1 UUID2 UUID3 | ||
| ``` | ||
|
|
||
| The script: | ||
| - Removes any `.sock` file whose UUID is NOT in the live set | ||
| - Cleans stale `.alias` symlinks pointing to removed sockets | ||
| - Kills and restarts the `slack-bridge` tmux session with the current `control-agent` UUID | ||
| - Verifies the bridge is responsive (HTTP 400 from the API = healthy) | ||
| This removes stale `.sock` files, cleans dead aliases, and restarts the Slack bridge. | ||
|
|
||
| **WARNING**: Do NOT use `socat` or any socket-connect test to check liveness — pi sockets don't respond to raw connections and deleting a live socket is **unrecoverable** (the socket is only created at session start). Only remove sockets for sessions that are confirmed dead via `list_sessions`. | ||

Bug: A reference in the control-agent startup checklist at pi/skills/control-agent/SKILL.md points to a non-existent section. The section was renamed, but the reference was not updated.
Severity: HIGH
Suggested Fix
In pi/skills/control-agent/SKILL.md, update the broken reference in the startup checklist. Change the text "(see Sentry Agent section)" to "(see Spawning sentry-agent section)" to correctly point to the renamed section.
Prompt for AI Agent
Review the code at the location below. A potential bug has been identified by an AI
agent.
Verify if this is a real issue. If it is, propose a fix; if not, explain why it's not
valid.
Location: pi/skills/control-agent/SKILL.md#L266-L295
Potential issue: In `pi/skills/control-agent/SKILL.md`, the startup checklist for the AI
agent contains a reference to a "Sentry Agent section" for instructions on how to launch
the `sentry-agent`. However, this section was renamed to "Spawning sentry-agent" in the
new code, but the inline reference was not updated. Because the AI agent follows these
instructions literally, it will be unable to find the correct section. This could cause
the agent to fail its startup sequence, specifically the step where it needs to spawn
the `sentry-agent`, which is a critical component for handling production alerts.

Summary
Audit and optimize all pi agent skills based on Anthropic skill authoring best practices. Key principles applied: only add context the model doesn't already have, use progressive disclosure, keep SKILL.md under 500 lines.
