What it does
Slack Subscribe is an agent skill from blockscout/frontend. Subscribe this session to replies in a Slack thread, then stop; replies are forwarded later as cross-session messages. Use after posting a question or a demo link to Slack when the run must resume on the colleague's answer, and to unsubscribe at teardown. Local Claude Code only.
Its SKILL.md is about 860 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts.
It sits in Agent Workflows, covering Session handoff. It works with Slack. The repository describes itself as: Front-end application for Blockscout chain explorer.
When your agent uses it
- Tasks that involve Session handoff
Example prompts
- “/slack-subscribe”
Workflow steps
3 steps, taken from the step headings in SKILL.md.
- Ready
- Subscribe, then stop
- Unsubscribe
What it can do on your machine
Read from SKILL.md and the folder at commit 9438622. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
Ships 1 file in scripts/, which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
blockscout.slack.com
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Slack Subscribe loads about 860 tokens when it runs. Until then it costs about 74 tokens; SKILL.md has 399 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.
Safety
Auto-check passed
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); the scripts in this folder are not scanned.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 399 words (~860 tokens).
“A session registers interest in a thread and stops. One other process — the Honk orchestrator — holds the only Slack Socket Mode connection, reads the registry, and forwards each reply into the registered session as a cross-session message. This…”
