What is stakeholder-announcement?

A workflow for drafting and posting infrastructure progress updates to the relevant Slack channels. Slack is a team messaging service used for workplace communication.

Use it to announce infrastructure work such as cloud identity setup, cluster preparation, or batch inference milestones.

It reduces the effort of deciding what to announce, where to post it, and how to structure the update.

Token cost

What it costs to keep this loaded

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	$0.00064	$0.01118
Opus 5.5	$0.00026	$0.00447
Sonnet 5.5	$0.00013	$0.00224
Haiku 4.5	$0.00006	$0.00112

Security

Grade A, and why

stakeholder-announcement 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 1mo 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.

How it starts

The opening of the file, as written. The whole thing — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Stakeholder Announcement

Drafts a structured progress announcement from recent work context (overall summary, GitHub activity, or explicit description) and posts it to the appropriate stakeholder Slack channels. Delegates posting to post-slack-message.

Prerequisites

SLACK_TOKEN, SLACK_COOKIE, and SLACK_USER in .env (same credentials used by slack-kb-individual)
post-slack-message skill available
Activity context: either an overall summary file (e.g., {NOTES_DIR}/{YEAR}/{MONTH}/{DAY}.overall.md), a GitHub activity file, or an explicit topic description from the user

Inputs

topic: the subject of the announcement (e.g., "batch inference GSA creation", "B300 cluster preparation", "WIF setup complete"). If omitted, inferred from the context file.
context: path to a summary file to draw from. Defaults to today's overall summary if it exists.
channels: target Slack channels. If not specified, inferred from the topic and stakeholder map (see below).
mode: --yes for immediate send; otherwise review mode (user confirms before posting).

Stakeholder Channel Map

Default channel mapping by topic area. The user can override at any step.

Topic area	Default channel(s)
Batch inference / batch API	`#batch-api-discussion`, `#ml-cp-batch`
GPU infrastructure / clusters	`#ml-infra-prod`, `#team-ml-infra-gpu`
WIF / identity / auth	`#cloud-platform-k8s`
Data platform / offline inference	`#proj-data-platform-gpu-offline-inference`
Davies / ML control plane	`#ml-cp-eng`
General ML infra	`#ml-infra-prod`

Steps

1. Gather context

Read the context file (overall summary, GitHub activity, or user-provided description). Extract:

What was done (accomplishments, merged PRs, created resources)
What stakeholders need to do (actions requested from them, e.g., "create terraform to give GSA access")
Relevant links (PR URLs, documentation links, issue links)
Timeline or next steps

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.
