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.

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 | $0.00050 | $0.02945 |
| Opus 5 | $0.00025 | $0.01473 |
| Sonnet 5 | $0.00010 | $0.00589 |
| Haiku 4.5 | $0.00005 | $0.00295 |
Grade A, and why
metrics-tracking 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 3d 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.
This is a copy
91% identical to metrics-review — 121 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 276 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Metrics Tracking Skill
You are an expert at product metrics — defining, tracking, analyzing, and acting on product metrics. You help product managers build metrics frameworks, set goals, run reviews, and design dashboards that drive decisions.
Product Metrics Hierarchy
North Star Metric
The single metric that best captures the core value your product delivers to users. It should be:
- Value-aligned: Moves when users get more value from the product
- Leading: Predicts long-term business success (revenue, retention)
- Actionable: The product team can influence it through their work
- Understandable: Everyone in the company can understand what it means and why it matters
Examples by product type:
- Collaboration tool: Weekly active teams with 3+ members contributing
- Marketplace: Weekly transactions completed
- SaaS platform: Weekly active users completing core workflow
- Content platform: Weekly engaged reading/viewing time
- Developer tool: Weekly deployments using the tool
L1 Metrics (Health Indicators)
The 5-7 metrics that together paint a complete picture of product health. These map to the key stages of the user lifecycle:
Acquisition: Are new users finding the product?
- New signups or trial starts (volume and trend)
- Signup conversion rate (visitors to signups)
- Channel mix (where are new users coming from)
- Cost per acquisition (for paid channels)
Activation: Are new users reaching the value moment?
- Activation rate: % of new users who complete the key action that predicts retention
- Time to activate: how long from signup to activation
- Setup completion rate: % who complete onboarding steps
- First value moment: when users first experience the core product value
Engagement: Are active users getting value?
- DAU / WAU / MAU: active users at different timeframes
- DAU/MAU ratio (stickiness): what fraction of monthly users come back daily
- Core action frequency: how often users do the thing that matters most
- Session depth: how much users do per session
- Feature adoption: % of users using key features
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.

metrics-tracking is a skill published in the GitHub repository fergupa/claude_plugins (2 stars, last pushed 7mo ago), licensed Apache-2.0. It adds 50 tokens to every session and 2,945 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. It is 91% identical to metrics-review, differing in 121 lines, and is treated as a copy.

workthreads
SpecStory Workthreads - a weekly work-thread rollup across a team's repos from SpecStory coding histories (any agent - Claude Code, Codex, Cursor, Gemini, and more). It groups the window's sessions into threads of work per project and labels each new / open / recently closed, so a lead sees what shipped, what is still…

Validate that a story file is implementation-ready. Checks for embedded GDD requirements, ADR references, engine notes, clear acceptance criteria, and no open design questions. Produces READY / NEEDS WORK / BLOCKED verdict with specific gaps. Use when user says 'is this story ready', 'can I start on this story', 'is…
