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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00051 | $0.00850 |
| Opus 5.5 | $0.00020 | $0.00340 |
| Sonnet 5.5 | $0.00010 | $0.00170 |
| Haiku 4.5 | $0.00005 | $0.00085 |
Grade A, and why
slack-standup-digest scanned grade A with 1 finding 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 14d 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.

Slack Standup Digest Automation
Set up a recurring automation that summarizes Slack activity into an async standup digest.
Prerequisites
Required integration
- Slack MCP must be installed in Settings → MCP.
Information to collect
Ask the user for:
- Source channels — which Slack channels to scan for updates (e.g.
#engineering,#frontend,#backend) - Target channel — where the digest should be posted (e.g.
#standup,#team-updates) - Schedule — when should the digest run? Default: weekday mornings at 9 AM
- Timezone — user's timezone (e.g.
America/New_York,Europe/London) - Auto-post or draft — should the digest post automatically, or be saved for the user to review and approve first?
- Grouping — how should updates be organized? Default: by project/channel, with sections for shipped work, active work, blockers, and decisions
Setup Workflow
Step 1 — Verify Slack MCP access
Confirm the Slack MCP integration is working:
Use the Slack MCP to search for recent messages in one of the source channels.
If it fails, tell the user to install the Slack MCP integration first.
Step 2 — Configure the schedule
Build a cron schedule from the user's preferences:
- Weekday mornings at 9 AM ET:
0 9 * * 1-5with timezoneAmerica/New_York - Daily at 8 AM UTC:
0 8 * * *
Step 3 — Build the digest prompt
Construct a prompt that includes:
- Source channels to scan
- Target channel for posting
- Lookback window (typically "since previous workday" — Friday→Monday for Monday digests)
- Grouping structure (by project, by channel, etc.)
- Whether to auto-post or draft
- What to highlight: blockers, decisions, shipped items, unanswered questions
Step 4 — Create the automation
Set OPENHANDS_HOST and AUTH_HEADER for the request below:
- OpenHands Cloud or Enterprise - a
<HOST>value is in your system prompt: use it asOPENHANDS_HOST, withAUTH_HEADER="Authorization: Bearer $OPENHANDS_API_KEY" - Local Agent Canvas - an Automation backend is listed in
<RUNTIME_SERVICES>: use itsurl_from_agentasOPENHANDS_HOST, withAUTH_HEADER="X-Session-API-Key: $OPENHANDS_AUTOMATION_API_KEY"
What ships with it
5 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.

slack-standup-digest is a skill published in the GitHub repository OpenHands/extensions (167 stars, last pushed today), licensed MIT. It adds 51 tokens to every session and 850 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
