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

slack-kb-individual 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.

The scan reads SKILL.md. This mod also ships 1 executable file (collect_individual_threads.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

The opening of the file, as written. The whole thing — 81 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Individual Slack activity collector

Use when collecting all Slack conversations a specific person participated in during a date range — useful for performance reviews, 1:1 prep, or building a picture of someone's contributions.

What it does

collect_individual_threads.py searches Slack for messages from a given user, deduplicates by thread, then fetches each thread root for reply count and preview. It outputs JSONL (one object per thread: thread_ts, channel, channelName, replies, preview, permalink).

Uses the Slack API directly (search.messages + conversations.replies) — no CLI dependencies. Thread fetching is concurrent (8 workers by default). Run via uv run for automatic dependency management (requests, python-dotenv).

Credentials: reads SLACK_TOKEN and SLACK_COOKIE from .env (searches up from cwd).

Two modes

Full scan

Searches the entire --after/--before date range newest-first and fetches every discovered thread. Pagination uses sort=timestamp&sort_dir=desc with sliding date windows to work around Slack's 100-page cap. Stops automatically at the retention boundary (older messages return empty).

uv run collect_individual_threads.py \
  --user tom.rochette --after 2024-10-06 --before 2026-04-08 \
  -o tom-threads.jsonl

Incremental update

Loads the existing output JSONL as a cache, then searches only a recent window (default: last 7 days). Threads found in the window are fetched (or re-fetched if they were already cached — they had recent activity). Cached threads outside the window are kept as-is.

# Daily — searches last 7 days, merges with existing cache
uv run collect_individual_threads.py \
  --user tom.rochette --incremental -o tom-threads.jsonl

# Custom window — last 14 days
uv run collect_individual_threads.py \
  --user tom.rochette --incremental --recent-days 14 -o tom-threads.jsonl

All options

Flag Description
--user (required) Slack username (e.g. tom.rochette)
--after / --before Full scan date range (YYYY-MM-DD). Slack's after: is exclusive.
--incremental Incremental mode: search recent window, merge with cache. Requires -o.
--recent-days N Days to search in incremental mode (default 7).
--channel Restrict search to a specific channel name.
--skip-threads List unique threads without fetching them (search only).
--workers N Concurrent thread fetch workers (default 8).
-o / --output Output path, or - for stdout. Default: <user>-threads.jsonl.

What ships with it

1 file 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.
