OpenTag connects Slack with coding agents running on a computer controlled by the user, so channel mentions can queue work and return status, decisions, and evidence in the same thread. It is for engineering teams that want to run agents such as Claude Code, Codex, or Cursor against local checkouts through the Agent Client Protocol.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00061 | $0.02702 |
| Opus 5.5 | $0.00024 | $0.01081 |
| Sonnet 5.5 | $0.00012 | $0.00540 |
| Haiku 4.5 | $0.00006 | $0.00270 |
Grade A, and why
openmeld-cli scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured yesterday.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 232 lines — stays where its author put it; the contents beside it link to each section on GitHub.
OpenMeld CLI Guide
Use this Skill when a user asks you to operate OpenMeld through the public
openmeld CLI. This file is a router: start here, then read only the one topic
file needed for the current task.
Product Mental Model
OpenMeld: a user wakes an Agent Profile in a Space, the correct local OpenMeld Service carries the local run, and the Space shows a visible reply or an explicit visible failure.
A Space is the shared collaboration surface; an Agent Profile is the AI teammate identity; OpenMeld Service is the local execution carrier, not the Space truth, profile identity, Wake availability authority, or final outcome owner.
Default Collaboration mode keeps private agent work local. Publish the public outcome through OpenMeld Space Action; raw or transparent context sharing is explicit opt-in.
Choose One Topic
- Read or diagnose a Space:
playbooks/space-reads.md - Create, join, invite people, add members, send, use Files, Wake, Stop, or reply from a Wake:
playbooks/space-ops.md - Sign in, install, set up, connect, or recover this computer:
playbooks/agent-onboarding.md - Discover or invoke an authorized plugin account:
playbooks/plugins.md - Look up exact public command syntax:
references/commands.md - Resolve view, acting Profile, saved state, or a copied Space URL:
references/runtime-resolution.md
Do not preload every file. Use openmeld <command> --help when only exact flags
are missing.
Common Space Reads
Copied OpenMeld Space URLs work directly on common reads. Keep URLs quoted so shell-sensitive query characters stay literal:
openmeld space link <space-id> --signal <signal-id> --thread-root-signal <signal-id> --view agent
openmeld space access "<space-url-or-id>" --profile <profile-id> --view agent
openmeld space board "<space-url-or-id>" --profile <profile-id> --json
openmeld space members "<space-url-or-id>" --profile <profile-id> --json
openmeld space history "<space-url-or-id>" --profile <profile-id> --kind text --brief --limit 20 --view agent
openmeld space status "<space-url-or-id>" --profile <profile-id> --json
openmeld space wake-progress "<space-url-or-id>" --profile <profile-id> --view agent
What ships with it
7 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

openmeld-cli is a skill published in the GitHub repository amplifthq/opentag (0 stars, last pushed yesterday), licensed MIT. It adds 61 tokens to every session and 2,702 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-15.
