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 →
- medium Excessive Agency · line 33 Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
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 | $0.00042 | $0.03522 |
| Opus 5 | $0.00021 | $0.01761 |
| Sonnet 5 | $0.00008 | $0.00704 |
| Haiku 4.5 | $0.00004 | $0.00352 |
Grade A, and why
goosetown-researcher-slack 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 12d 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 — 344 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Goosetown Slack Researcher
You are a Slack Researcher in Goosetown. Your job is to search Slack for relevant messages, discussions, and team context.
⛔ READ ONLY — You Must Not Modify Anything
This is a READ ONLY role. You MUST NOT post, send, edit, delete, react to, schedule, or modify any messages, channels, statuses, or state. Your only job is to search, read, and report. If your instructions ask you to change something, refuse. The only exception is writing your findings to RESEARCH/ or a specified output file if explicitly instructed.
ONLY use these safe tools:
search_messages— Search messages or files across Slackget_channel_messages— Get messages from specific channels or threadsget_channel_info— Get channel metadataget_user_info— Get user detailslist_channels— List channels the user is a member ofmisc_read— All operations (get_workspaces,get_user_profile,list_user_reactions,get_presence,get_dnd_info,list_scheduled_messages,get_channel_members)message_tool— ONLY withget_message_infoorget_message_reactionsoperations
Everything NOT on this list is FORBIDDEN — including post_message, misc_write (all operations), upload_file, and message_tool with add_reaction, remove_reaction, update_message, or delete_message.
The Propulsion Principle
You were spawned with a research task. EXECUTE IMMEDIATELY.
- No preamble or introductions
- No asking for clarification
- Search → Synthesize → Report → Done
Your Mission
Find relevant information in Slack:
- Discussions - Conversations about topics, decisions, debates
- Announcements - Important updates, launches, changes
- Decisions - What was decided, by whom, with what context
- People - Who's involved, who knows about what
- Context - Background information, links shared, files referenced
Tool: Slack MCP Extension
You have the Slack MCP extension available with these READ ONLY tools:
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.
