feat(slack-researcher): add /ce-slack-research skill and improve agent#538
Conversation
Restructure Step 1 to check Slack MCP availability via platform tool discovery before doing any work, with a read-only probe as fallback. Add freeform prompt handling so conversational inputs get normalized into search topics. Strengthen tool guidance to stop on mid-workflow failures rather than substituting non-Slack tools.
…t search Add a thin wrapper skill that makes the slack-researcher agent directly invocable via /ce-slack-research, instead of only being discoverable as a sub-agent of ce:brainstorm, ce:plan, and ce:ideate. Agent improvements: - Set model to sonnet (benchmarked against opus with equivalent quality at 30-40% fewer tokens and faster execution) - Add search modifiers from official Slack plugin: on:, has::emoji:, has:file, and file content search via content_types="files" README: Move ce-sessions and ce-slack-research into a new "Research & Context" section, keeping Core Workflow focused on the brainstorm-plan- review-work-compound chain.

Add an invariant test that fails when a name in STALE_SKILL_DIRS or in EXTRA_LEGACY_ARTIFACTS_BY_PLUGIN["compound-engineering"].skills matches a current directory under plugins/compound-engineering/skills/. If a retired skill is ever re-added to the plugin, the stale registry entry would make cleanupStaleSkillDirs() fingerprint-match the freshly-installed skill and delete it on every install. The test caught a pre-existing collision: ce-update was erroneously seeded into the legacy artifacts list in #609 even though it has been a live skill since #538. Remove it from the registry and flip the assertions in plugin-legacy-artifacts.test.ts and cli.test.ts that were locking in the buggy behavior (the CLI test was effectively asserting that cleanup would move a user's live ce-update install into legacy-backup). Export STALE_SKILL_DIRS so the invariant test can import it. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
Adds
/ce-slack-research— a directly invocable entry point for the slack-researcher agent, which was previously only discoverable as a sub-agent of/ce:brainstorm,/ce:plan, and/ce:ideate. The skill accepts freeform input ("What did we say about free trial recently?") or structured queries ("free trial in #proj-reverse-trial after:2026-03-01"), dispatches to the agent, and returns an interpreted digest with workspace identity, research-value assessment, and cross-cutting analysis.Also improves the agent itself:
on:YYYY-MM-DD,has::emoji:(for finding approved/decided items),has:file, andcontent_types="files"for document search. Sourced from the official Slack plugin's search skill.ce-sessionsandce-slack-researchinto a new "Research & Context" section, keeping Core Workflow focused on the brainstorm-plan-review-work-compound chain.Test plan
Tested with 7 queries across multiple dimensions:
research value: nonewith workspace IDPrecondition checks validated: agent stops cleanly on auth failure without falling back to non-Slack tools (confirmed across 5 parallel runs).
