What is describe-colleague?

A colleague-profile workflow that combines a person's Slack conversations and GitHub activity into a written summary of strengths, weaknesses, interests, and avoidances.

Use it to research a colleague's commits, pull requests, and team messages, then save a structured profile for later reference.

It turns scattered work activity into one profile while requiring the relevant accounts and notes to be available.

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	$0.00033	$0.00572
Opus 5	$0.00016	$0.00286
Sonnet 5	$0.00007	$0.00114
Haiku 4.5	$0.00003	$0.00057

Security

Grade A, and why

describe-colleague 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 7d 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.

Describe Colleague

Generates a structured profile for a colleague by synthesizing their Slack and GitHub activity, capturing strengths, weaknesses, interests, and avoidances.

Prerequisites

Slack MCP server connected and authenticated
gh CLI authenticated
NOTES_DIR environment variable set (resolved via ~/.agents/scripts/get-env NOTES_DIR)
Colleague identifier ({COLLEAGUE}) provided as argument or from context

Steps

Retrieve NOTES_DIR from environment:
```
~/.agents/scripts/get-env NOTES_DIR
```

Search GitHub for the colleague's contributions using gh:

gh search commits --author={COLLEAGUE} --limit 50
gh search prs --author={COLLEAGUE} --limit 50

Review their Slack messages and threads via the Slack MCP server. Do not read local files.
Synthesize observations into the profile format below.
Write the profile to {BASE_DIR}/colleagues/{COLLEAGUE}.md.

Output Format

# Strengths

- <strength>

# Weaknesses

- <weakness>

# Interests

- <topic>

# Avoids

- <topic>

# Other relevant information

- <item>

Example Usage

Scenario 1: Profile a specific colleague

/describe-colleague alice

Searches GitHub for alice's commits and PRs, reviews her Slack messages, then writes a profile to {NOTES_DIR}/colleagues/alice.md.

Scenario 2: Update an existing profile

/describe-colleague bob

If {NOTES_DIR}/colleagues/bob.md already exists, overwrite it with a refreshed profile incorporating recent activity.

Scenario 3: Colleague with limited GitHub activity

/describe-colleague carol

Carol's contributions are primarily via Slack. Profile is weighted toward Slack observations, with a note that GitHub data is sparse.

Useful Commands Reference

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.
