Set up a Slack notification channel (Sentinel) for a colony by driving the browser — reuse or create the "Hive Sentinel" Slack app from a JSON manifest, install it, capture the bot + app tokens, create/select the channel via the Slack API, and turn Sentinel on so the colony can ping the user on Slack and accept replies. Use when the user asks to "set up Slack notifications", "get pinged on Slack", "connect Slack for alerts", "set up Sentinel on Slack", or clicks the in-app "Set this up with the agent" button on the Slack channel step. Requires hive.browser-automation.

Claude Code, by hand (all projects)
git clone --depth 1 https://github.com/aden-hive/hive.git /tmp/hive mkdir -p ~/.claude/skills cp -R /tmp/hive/core/framework/skills/_default_skills/slack-notifications-setup ~/.claude/skills/slack-notifications-setup

What it costs your context
Agent Skills load in three steps. Tokens counted with the o200k tokenizer; your model's count will differ a little.
| When | What loads | Cost |
|---|---|---|
| Every session | Name and description | 136 tok |
| When the agent uses it | The SKILL.md instructions | 2,554 tok |
| Only if opened | No bundled files | — |
Until it is used, hive.slack-notifications-setup costs about 10× less than the median MCP server we measured (1,362 tokens on every turn). Installing all 24 skills from aden-hive/hive would load 1,783 tokens of descriptions. Skills vs MCP study

- Slack Notifications Setup (Sentinel)
- Before you start — check what already exists
- Step 1 — Create the app from a JSON manifest
- Filling the manifest editor (JSON tab — do this, nothing else)
- Step 2 — Generate the App-Level Token (xapp-…)
- Step 3 — Install to the workspace, get the Bot Token (xoxb-…)
- Step 4 — Store both tokens with sentinelsetup
- Step 5 — Channel: do it with the Slack API, not the UI
- Step 6 — Turn Sentinel on and verify

SOP for debugging browser automation failures on complex websites. Use when browser tools fail on specific sites like LinkedIn, Twitter/X, SPAs, or sites with Shadow DOM.
11k1039 tok idle · 1,605 in use - hive.browser-automationaden-hive/hive
Required before any hive-browser CLI command. The browser is driven from the terminal by running `hive-browser <command> ... --json` via terminal_exec — not via MCP tools. Teaches the browser lifecycle rules (the bridge attaches to the USER'S running Chrome — never kill or launch browser processes; timeouts are transport issues, not crashes), the screenshot + coordinate workflow (hive-browser interact with a fractional coordinate) that reaches shadow-DOM inputs selectors can't see, the viewport-fraction coordinate rule (not pixels), rich-text editor quirks ("send button stays disabled" failures), and CSP gotchas. Covers Chrome via CDP through the GCU Beeline extension.
11k142 tok idle · 11,043 in use - hive.chart-creation-foundationsaden-hive/hive
Required reading whenever any chart_* tool is available. Teaches the one-tool embedding contract (call chart_render → live chart appears in chat AND a downloadable PNG lands in the queen session dir), the ECharts (data viz) vs Mermaid (structural diagrams) decision, the BI/financial-grade aesthetic baseline (no chartjunk, restrained palette, proper typography, single message per chart), and the canonical spec patterns for the 12 most-common chart types. Skipping this leads to 1990s-Excel charts, missing downloads, and the agent writing markdown image links by hand instead of letting chart_render drive the UI.

Claim tasks, record step progress, and verify SOP gates in the colony SQLite queue. Applies when your spawn message includes a db_path field.

Proactively extract critical values from tool results into working notes before automatic context pruning destroys them.
11k24 tok idle · 231 in use - hive.error-recoveryaden-hive/hive
Follow a structured recovery decision tree when tool calls fail instead of blindly retrying or giving up.
11k25 tok idle · 278 in use - hive.image-generationaden-hive/hive
Required before calling image_generate. Create and edit images from a prompt — generate an image, make a picture / logo / illustration / icon / banner / poster / thumbnail / hero image / mockup / product shot / social graphic, or edit / restyle / combine existing images from reference images. Uses OpenAI gpt-image-2 through the Hive image service, billed to the user's Hive credits like an LLM call (no API key needed). Teaches the exact call shape, the quality/cost tradeoff (quality="low" is the default and cheapest), reference-image editing, how to show the result to the user with attach_file, and the failure modes (out of credits, model unavailable, moderation).
11k149 tok idle · 1,193 in use - hive.linkedin-automationaden-hive/hive
Read before automating LinkedIn with browser_* tools. LinkedIn combines shadow DOM (#interop-outlet), strict Trusted Types CSP that silently drops innerHTML, Lexical composer, native beforeunload dialogs that hang the bridge, and aggressive spam filters — each has bitten us at least once. Verified flows for profile messaging, connection-request acceptance, feed composition, and search. Requires hive.browser-automation. Verified against logged-in production 2026-04-11.
