Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 3 findings, 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 →

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 | $0.00138 | $0.01953 |
| Opus 5 | $0.00069 | $0.00977 |
| Sonnet 5 | $0.00028 | $0.00391 |
| Haiku 4.5 | $0.00014 | $0.00195 |
Grade A, and why
manage-dashboard-widgets 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 10d 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 — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Managing dashboard widgets
For PostHog engineers working on dashboard widget tiles in the repo.
Human overview: products/dashboards/CONTRIBUTING.md
In scope: widget tiles (widget_id on DashboardTile) — ship new types or change shipped types.
Out of scope: adding an existing type to a dashboard (MCP dashboard-widget-catalog-list → dashboard-widgets-batch-add); insight tiles, text cards, button tiles.
1. Route first
| Request | Path | Start here |
|---|---|---|
New widget_type that does not exist |
Ship | §2 Ship a new type — intake mandatory |
| Change a shipped type (config, query, UI, layout, RBAC, deprecate) | Update | §3 Update a shipped type — skip intake |
| Add existing type to a dashboard | — | MCP only — not this skill |
| Chart / trend / graph for product metrics on a dashboard | — | Insight tile — architecture.md § Charts |
Shipped types (code truth): architecture.md § Shipped types.
2. Ship a new widget_type
Intake — ask before coding
Mandatory for new types only. Read widget-intake.md and:
- Discover product UI in the repo — concrete components/scenes before generic tile-body questions.
- Apply defaults and inference (
groupId, copy spine, list UX) — never AskQuestion banned topics. - Resolve ambiguity — one batched follow-up for gaps, max 6 questions (open fields).
- Post the spec table; get confirmation before checklist §1.

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-dashboard-widgets is a skill published in the GitHub repository PostHog/posthog-foss (714 stars, last pushed yesterday), licensed MIT. It adds 138 tokens to every session and 1,953 once invoked, about $0.0007 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.
