comms-context

comms-context is a skill for Claude Code, Codex from lugassawan/swe-workbench. It costs 51 tokens per session (786 once invoked), scanned A, original, MIT.

A context-gathering helper for Slack, a team messaging service, and PagerDuty, an incident-alerting system. It collects people involved, the timeline, and the current status from supported references.

In plain words
What is it for?
Use it when investigating a Slack thread, PagerDuty incident, page, or on-call escalation.
Why use it?
It removes the need to manually piece together messages and incident details during on-call work.

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.

Security

Grade A, and why

comms-context 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 3d 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 — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.

When to invoke

Auto-loads when the caller references:

  • Slack permalink: <workspace>.slack.com/archives/<channel>/p<timestamp>.
  • PagerDuty incident URL: <subdomain>.pagerduty.com/incidents/<id>.
  • PagerDuty incident ID: a bare incident ID mentioned alongside a PagerDuty context clue (e.g. "PagerDuty incident PD-4521"), when a PagerDuty MCP tool (mcp__pagerduty__*) is reachable in-session.
  • Free-text on-call signal: text describing a page, on-call escalation, or Slack thread reference.

If no reference is present, exit cleanly.

Adapters

Slack permalink

  • Trigger: Slack permalink URL (<workspace>.slack.com/archives/<channel>/p<timestamp>).
  • Fetch: mcp__slack__get_permalink_thread with the channel and timestamp parsed from the URL (aspirational — this plugin ships no Slack MCP integration; this recipe activates only if the user has one connected). Resolve the permalink to a channel + timestamp, then fetch the root message and its thread replies.
  • Extract → block fields: message author plus every distinct thread replier → Participants; message and reply timestamps in chronological order → Timeline; if the thread reaches a visible resolution or decision, summarize it, else "ongoing" → Status; the permalink itself → Source.
  • Degrade: If no mcp__slack__* tool is reachable, emit comms-context: Slack MCP unavailable; proceeding without context. Never fabricate thread content or participants.

PagerDuty incident

  • Trigger: PagerDuty incident URL (<subdomain>.pagerduty.com/incidents/<id>), or a bare incident ID paired with a PagerDuty context clue — gated on a reachable mcp__pagerduty__* tool (no other skill claims PagerDuty IDs, so this trigger is unconditional once the URL or a PagerDuty-labeled ID is present; no cross-skill disambiguation is needed here).
  • Fetch: mcp__pagerduty__get_incident with the incident ID or URL (aspirational — this plugin ships no PagerDuty MCP integration; this recipe activates only if the user has one connected). Fetch incident details, the escalation timeline, and current on-call responders.
  • Extract → block fields: assignee plus on-call responders → Participants; triggered/acknowledged/resolved timestamps in order → Timeline; current incident status (triggered/acknowledged/resolved) → Status; incident URL → Source.
  • Degrade: If no mcp__pagerduty__* tool is reachable, emit comms-context: PagerDuty MCP unavailable; proceeding without context. Never fabricate incident status or timeline. On auth error, surface the raw error. On empty/404, say so; do not guess.

What ships with it

Changes

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.
