Tools & capabilities
Pincushion Plugin tools 65
get_annotationsRetrieve annotation pins from the .feedback/ directory. Filter by page URL, LWC component name, or status. Use this to understand what feedback exists before making changes.search_annotationsFull-text search across all annotation comments, selectors, component names, and tags.get_feedback_summaryGet a high-level rollup of all open feedback: counts by status, page, and component. Use this to plan what to address first.get_component_feedbackGet all feedback pins targeting a specific LWC component, with a plain-language summary ready for implementation. Returns element selectors, comments, and thread history.resolve_annotationMark an annotation as resolved after addressing the feedback. Optionally add a resolution comment explaining what was changed.add_agent_replyAdd a reply to an annotation thread (e.g. to ask a clarifying question or note a finding).get_reply_candidatesUsed by /pincushion-replies. Returns pins where Pincushion AI should respond, with each candidate tagged by trigger reason. Two triggers: (a) "mention" — the latest thread message contains @pincushion AND was authored by a human; (b) "reply-on-bot-pin" — the pin was originally authored by Pincushion AI and the latest message is from a human. Skips resolved/archived pins and any pin where the latest message is already bot-authored (idempotency). Newest-first ordering so the slash command can pace replies.add_bot_replyPost a Pincushion AI reply to a pin's thread. Hardcodes author="Pincushion AI" and authorEmail="pincushion-bot@pincushion.io" so the Chrome extension applies bot styling. ONLY call from the /pincushion-replies flow — never as a generic reply. Refuses to post if the latest thread message is already bot-authored (defense-in-depth idempotency).get_pending_critiquesUsed by /critique-latest-deploy. Lists pending critique requests queued by the deploy-hook for the current license. Newer receipts also include a deployment event, prior page outcomes, project-page inventory, and latest per-device capture receipts for truthful local reconciliation before Crit runs. Newest-first. Free on all plans (the gating happened at enqueue time on the deploy-hook side: Pro/Team — including trial-Pro — always enqueue; free licenses enqueue while their monthly AI-action pool has headroom).get_pending_deployment_frame_refreshesLists production deployment frame-refresh work independently of the Critique queue. Use this even when autoCritique is false. The result is redacted: it contains no deployment URL/hash, browser state, storage path, or capture proof. Start a selected run before capturing.start_deployment_capture_runStarts one short-lived local frame-refresh run for an exact deployment and returns its opaque proof once. Keep the proof only in process and pass it to authenticated upload_page_snapshot/record_deployment_page_result/complete_deployment_capture_run calls; never put it in capture-snapshot, shell argv, a report, pin, status message, or file.complete_deployment_capture_runRequests server-side frame-refresh completion after all exact page/device receipts have been recorded. The server rejects missing, stale, replayed, cross-deployment, or expired capture-run evidence and never treats a queue state as a current frame.- +53 more on the listing page
Agy Bridge tools 6
analyze_filesDelegate file analysis to the Antigravity CLI (Gemini) instead of reading files yourself. USE THIS whenever a file is large (>200 lines) or the task spans more than 3 files: logs, database dumps, generated code, cross-file reviews, comparisons. The files never enter your context — only the answer does.deep_searchDelegate codebase archaeology to the Antigravity CLI: git log/diff/blame spelunking, wide greps across a repo, 'when/why did X change', 'where is Y used'. USE THIS instead of running many search commands yourself — it saves your context.web_lookupDelegate a web/documentation lookup to the Antigravity CLI (Gemini with web access): library docs, API references, error messages, current versions, external knowledge. USE THIS when you need information you don't have or that may be newer than your training data.adversarial_reviewGet an adversarial second opinion from a different model family (Gemini Pro). ALWAYS use this for plan critiques, design reviews, and pre-merge code review: it hunts for flaws, edge cases, security issues, and unstated assumptions you may have missed.follow_upContinue a previous Antigravity session by session_id (returned by every other tool). USE THIS for follow-up questions about a prior delegation — the full prior context is already on agy's side, so you don't resend anything.delegateRaw delegation to the Antigravity CLI for heavy tasks that don't fit the other tools. agy has full tool access (shell, file reads, web) in the given cwd.
