Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00209 | $0.01975 |
| Opus 5 | $0.00105 | $0.00988 |
| Sonnet 5 | $0.00042 | $0.00395 |
| Haiku 4.5 | $0.00021 | $0.00198 |
Grade A, and why
manage-lexicon 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 8d 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 — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Manage Lexicon
Engine required — resolve an engine per
ENGINE.md: one named in the conversation or loaded instructions is mandatory (not set up → offer/mixpanel:installfor it); otherwise use the Mixpanel MCP server, or offer/mixpanel:installif it's unavailable.
This skill manages a Mixpanel project's Lexicon — the registry of tracked events and properties. It scores metadata quality, bulk-enriches missing descriptions / display names / tags, resets metadata, triages data quality issues, and renames or deletes tags. It runs as a single interactive session per project; do not invoke in parallel for the same project.
Components
The skill is built from a small set of abstractions. The Execution section below tells you how to use them.
Canonical commands
Each command lives in its own file under commands/ and is loaded on demand. Match commands explicitly (user names them) or implicitly (message matches a trigger phrase below).
| Command | File | Match if message contains any of |
|---|---|---|
score-lexicon |
commands/score-lexicon.md |
score, audit, health, grade |
enrich-and-tag |
commands/enrich-and-tag.md |
enrich, fill, auto-tag, generate descriptions |
reset-lexicon |
commands/reset-lexicon.md |
reset, wipe, clear metadata, clear tags |
review-issues |
commands/review-issues.md |
issues, drift, anomaly, data quality |
manage-tags |
commands/manage-tags.md |
rename tag, delete tag, merge tags |
If a message matches more than one command, show the Command menu instead.

What ships with it
6 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.

manage-lexicon is a skill published in the GitHub repository mixpanel/ai-plugins (15 stars, last pushed 4d ago), licensed Apache-2.0. It adds 209 tokens to every session and 1,975 once invoked, about $0.0010 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
