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 | $0.00047 | $0.01080 |
| Opus 5.5 | $0.00019 | $0.00432 |
| Sonnet 5.5 | $0.00009 | $0.00216 |
| Haiku 4.5 | $0.00005 | $0.00108 |
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 2d ago.
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.

OpenMeld CLI
OpenMeld gives local agents access to an Organization's shared resources, cloud Center Agent, and Agents on connected computers. Use it when one of those resources helps complete the user's task. Complete self-contained local work normally; installing this Skill is not a reason to create a Space, consult another Agent, or upload work.
Choose the smallest useful workflow
- Identify what is missing: shared context, an existing artifact, a particular Agent or computer, or work that must run later. Reuse a known resource.
- Read the matching topic below, then make the smallest relevant lookup. Resolve discoverable IDs yourself. Ask only when the choice changes the audience, acting identity, target, timing, or scope and context cannot resolve it.
- Carry out the authorized work and check its result. A request to send, delegate, save, or schedule already authorizes that action within its stated scope; do not ask again. When involving another Agent or sharing local work would add scope, explain the specific benefit and ask before doing it.
| Need | Read |
|---|---|
| Existing Space context, history, members, or Wake progress | Space reads |
| Create a Space, add this session, send, Wake another Agent, or finish a received Wake | Space operations |
| Organization knowledge, Center Agent consultation, delegated work, or document updates | Center Agent |
| Team/My Files, Organization Skills, Projects, or scheduled Routines | Resource commands |
| Connected app actions through Plugins | Plugins |
| Sign in, connect this computer, or recover its local agents | Onboarding |
| Acting Profile, copied URL, output format, or account selection | Command context |
Read only the topic needed. Follow relative links from this folder or the
public entry. This guide
requires CLI 0.3.237 or later; check openmeld --version when a command is
missing or the installation is unknown. Use openmeld <command> --help for
additional flags. The guide cannot add a missing command or cloud capability.
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 2d ago), licensed MIT. It adds 47 tokens to every session and 1,080 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.
