Slackbot Builder is an agent skill from swyxio/skills. Design or harden Slack bot transport and interaction architecture: signed Events API ingress, fast acknowledgement, idempotency, causal thread context, Block Kit actions, message rendering correctness (Markdown, rich text, links and citations), durable agent execution, multi-workspace operation, or Slack-specific delivery of typed follow-up controls and privacy-bounded execution receipts. Use for new Slack bots, broad Slack architecture audits, or changes to these Slack contracts. Do not use for deployment…
Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 16 other files (for example `agents/openai.yaml`, `analytical-visualizations.md` and `answer-quality-and-receipts.md`).
It sits in Writing & Content, covering Chatbots and conversational support, UI design and Visual regression testing. It works with Slack. The repository describes itself as: Agent skills for Claude Code and other AI agents. The licence is MIT.
Read from SKILL.md and the folder at commit 038ef34. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Slackbot Builder loads about 2.1k tokens when it runs. Until then it costs about 181 tokens; SKILL.md has 800 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

This skill has two routing modes:
Keep Slack as a thin adapter: verify and acknowledge requests, acquire Slack-scoped context, call the Slack Web API, render bounded Slack UI, and delegate application behavior to a channel-agnostic core.
| Level | Theme | What you add | Reference |
|---|---|---|---|
| L0 | Skeleton — it responds | /health, /events, signature verify, url_verification, fast 200 | level-0-skeleton.md |
| L1 | Responsive Q&A (MVP) — a working bot | 3s ack + async work, event_id dedupe, ignore bots, strip mentions, threaded chat.postMessage, thin fetch wrappers, JSON logs + trace id | level-1-mvp.md |
| L2 | Context-aware — feels conversational | shared thread sessions, root + newest causally-prior tail, merged persisted state, DMs, empty-mention nudge, 👀 reaction + assistant.threads.setStatus | level-2-context.md |
| L3 | Interactive / agentic — acts, human in the loop | /interactions (signed), state-aware approvals that resolve in place, remaining-draft bulk actions, dry-run validation, stateful routing + owned-resource resolution, rich/actionable drafts, file/media controls + settings modal, live status streaming | level-3-interactive.md |
| L4 | Native agent surface — first-class agent UX | Agents & AI Apps container, assistant_thread_started greeting + suggested prompts, thread titles, native text streaming (chat.startStream/appendStream/stopStream) mapping your emit stream to a typed answer + tool-call timeline, graceful fallback to the message flow | level-4-native-agent.md |
| L5 | Hardened — won't page you at 2am | per-thread durable serialization, long-running signed callbacks + durable URL, App Home prefs/dashboard, rate-limit backoff + ok:false handling, sanitized errors, storage TTLs, service-user attribution + audit, full observability, security/testing checklists | level-5-hardened.md |
| L6 | Multi-surface / scale — polished platform | one core across web/Slack/cron, multi-workspace/tenancy, queues + backpressure for heavy work, target caching, usage analytics + answer-quality feedback, break-glass/degraded config | level-6-scale.md |
| Specialized contract | Reference |
|---|---|
| Message formatting, Markdown conversion, clickable links, or citation rendering | message-formatting.md |
| Slack search, files, PDFs, or requester-scoped retrieval | search-and-retrieval.md |
| Native charts/tables or hosted analytical artifacts | analytical-visualizations.md |
| Mixed Slack evidence plus deterministic application/provider data | Read both search-and-retrieval.md and analytical-visualizations.md |
| Slack rendering of typed follow-up controls or execution receipts | answer-quality-and-receipts.md |
| Generated images and iteration controls | image-generation.md |
| Thread persistence, ordering, resource routing, or mutations | stateful-agent-workflows.md |
| Cloudflare ingress, dispatch, dedupe, or durable acceptance | cloudflare-durable-ingress.md |
When diagnosing an existing bot, inspect its current code and tests before choosing a level. A production bot can have an L2 retrieval defect without the task becoming an L5 hardening project.
Universal invariants — true at every level (the level-specific opinions live in their level files so they load only when needed):
thread_ts as the conversation boundary. Load
only causally prior messages, paginate before trimming, and preserve
file/image-only context when the feature is multimodal.mrkdwn.Level-specific opinions (full rationale + war stories in the linked file): mutations require a human, inline flags configure the core, route on the raw request not the context, interactive actions ack the click instantly + batch ops show a started state and terminal summary (plus incremental progress when practical), artifacts get iterate-button + settings-modal affordances → L3; instrument every model call (not just text), slow work runs in durable execution not a background promise, every entry surface protected equally, every job ends in a guaranteed result-or-error delivered by the right surface mechanism → L5; image-gen specifics → image-generation.md.
TypeScript; a small HTTP framework (Hono, Fastify, Express, or native route
handlers); shared KV/Redis/Postgres for state; raw Slack Web API fetch wrappers
unless an SDK is already established; a queue or platform-native background
execution for work over 1–2s; a web page for long output. Add slash commands,
modals, Socket Mode, or workflow steps only when the product need is clear.

Design or harden Slack bot transport and interaction architecture: signed Events API ingress, fast acknowledgement, idempotency, causal thread context, Block Kit actions, message rendering…. Slackbot Builder is an agent skill from swyxio/skills. Design or harden Slack bot transport and interaction architecture: signed Events API ingress, fast acknowledgement, idempotency, causal thread context, Block Kit actions, message rendering correctness (Markdown, rich text, links and citations), durable agent execution, multi-workspace operation, or Slack-specific delivery of typed follow-up controls and privacy-bounded execution receipts.
Slackbot Builder fits situations like: broad Slack architecture audits; changes to these Slack contracts; standalone visual testing; unrelated copywriting.
Run `npx skills add swyxio/skills --skill slackbot-builder -a claude-code`. Or copy the skill folder (slackbot-builder in swyxio/skills) into .claude/skills/slackbot-builder in your project. Claude Code loads it when a task matches its description.
Run `npx skills add swyxio/skills --skill slackbot-builder -a codex`. Or copy the skill folder (slackbot-builder in swyxio/skills) into .agents/skills/slackbot-builder in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add swyxio/skills --skill slackbot-builder -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/slackbot-builder, .gemini/skills/slackbot-builder, .github/skills/slackbot-builder and .opencode/skills/slackbot-builder in your project.
SKILL.md names no scripts, command-line tools or credentials: Slackbot Builder is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Slackbot Builder is published under the MIT licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 2.1k tokens (SKILL.md is roughly 8.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
