## What it does

The skill reads usage records from the `cost-tracking` namespace for the requested period and calculates model costs. Its report includes total spend, remaining budget, model and agent breakdowns, plus active alerts.

It also groups records by processing tier: booster bypasses, Haiku work, and Sonnet or Opus work. When `docs/benchmarks/runs/latest.json` exists, it reads measured booster and baseline values from that file. That matters when part of the workload was eligible for a booster route.

For usage retrieval it calls `memory_search`, `memory_list`, or `memory_retrieve` against `cost-tracking`. The `agentdb_hierarchical-*` tools route by tier rather than namespace, so they are not suitable for this report. Budget settings are retrieved with `memory_retrieve` before alert thresholds are checked.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add ruvnet/ruflo --skill cost-report -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/cost-report/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/cost-report/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add ruvnet/ruflo --skill cost-report -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/cost-report/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add ruvnet/ruflo --skill cost-report -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/cost-report/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install ruvnet/ruflo cost-report
```

2. **Manually: put the files in place**
- File: `.github/skills/cost-report/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add ruvnet/ruflo --skill cost-report -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/ruvnet/ruflo --path plugins/ruflo-cost-tracker/skills/cost-report
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/cost-report/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add ruvnet/ruflo --skill cost-report -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

## When to use it
- calculate token costs by model
- break down spending by agent
- check budget utilisation
- surface active budget alerts
- include measured booster benchmark data

## Example prompts
- Create a cost report for today.
- Show spending by agent and model for the selected period.
- Check the budget status and active cost alerts.

# Cost Report

Generate a comprehensive cost report showing token usage, USD costs, and budget utilization for the specified period.

## When to use

When you need to understand current spending -- how much each agent costs, which models consume the most budget, and whether you're on track to stay within budget.

## Steps

1. **Retrieve usage** -- call `mcp__plugin_ruflo-core_ruflo__memory_search` (or `_list` / `_retrieve`) on the `cost-tracking` namespace for the specified period (default: today). The `memory_*` tools route by namespace string; the `agentdb_hierarchical-*` tools do **not** (they route by tier `working|episodic|semantic`), so don't use them here. See [ruflo-agentdb ADR-0001 §"Namespace convention"](../../../ruflo-agentdb/docs/adrs/0001-agentdb-optimization.md) for the routing contract.
1a. **Read measured booster data** -- if `docs/benchmarks/runs/latest.json` exists, load it via `Bash`-shelled `node -e 'console.log(JSON.stringify(JSON.parse(require("fs").readFileSync("docs/benchmarks/runs/latest.json")).summary))'`. This provides Tier 1 measured values — booster cost/edit ($0), avg latency, win rate, plus any LLM baseline that was run (Gemini, Sonnet 4.6, Opus 4.7 latencies and per-edit costs). Use these in step 4 for the **measured** Tier breakdown rather than estimated.
2. **Compute costs** -- for each record, calculate cost using model pricing:
   - Haiku: $0.25/M input, $1.25/M output
   - Sonnet: $3.00/M input, $15.00/M output
   - Opus: $15.00/M input, $75.00/M output
   - Include cache write/read costs where applicable
3. **Aggregate by model** -- sum costs per model, compute percentage share
4. **Aggregate by tier** -- classify each record as Tier 1 / Tier 2 / Tier 3 using **three** signals (in priority order): (a) bench data from step 1a — for any record that maps to a measured booster intent, use $0 / measured-latency directly; (b) the `[AGENT_BOOSTER_AVAILABLE]` flag stored by the `cost-booster-route` skill in `cost-tracking`; (c) the model name as fallback (`haiku` → Tier 2; `sonnet`/`opus` → Tier 3). Sum costs per tier, compute share, and count Tier 1 bypasses. The tier breakdown is the most actionable single line — it tells the user what fraction of Sonnet/Opus spend was Tier 1-eligible.
5. **Aggregate by agent** -- sum costs per agent, include the model each agent used
6. **Check budget** -- recall budget configuration via `memory_retrieve` and compute utilization percentage, check alert thresholds (50%/75%/90%/100%)
7. **Report** -- display: total cost, budget remaining, **tier breakdown** (Tier 1 / Tier 2 / Tier 3), model breakdown, agent breakdown, active alerts. See REFERENCE.md §"Cost report shape" for the canonical layout.
