cost-booster-routeRoute tasks through hooksroute, partition by Agent Booster availability, and report Tier 1 bypass utilization with $0 cost
Cost Booster Route is an agent skill from ruvnet/ruflo. Route tasks through hooksroute, partition by Agent Booster availability, and report Tier 1 bypass utilization with $0 cost
Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Agent Workflows. The repository describes itself as: 🌊 The original agent harness. Deploy intelligent multi-player swarms, coordinate autonomous workflows, and build conversational AI systems. Features adaptive memory…. The licence is MIT.
6 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 6c04654. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:

No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Cost Booster Route loads about 681 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 248 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
allowed-tools: mcp__plugin_ruflo-core_ruflo__hooks_route, mcp__plugin_ruflo-core_ruflo__memory_search, mcp__plugin_Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/cost-booster-route/SKILL.md (or your agent's skills folder).Wraps mcp__plugin_ruflo-core_ruflo__hooks_route and reports how many tasks the 3-tier router classified as Agent Booster (Tier 1) eligible. Tier 1 bypasses run as WASM transforms — no LLM call, structurally $0 cost.
Before a batch of similar tasks, or when cost-report shows Sonnet/Opus spend on descriptions that look like simple transforms (var-to-const, add-types, add-error-handling, async-await, add-logging, remove-console).
Collect tasks — single arg or recent entries from cost-tracking via memory_search. Cap batch at 50.
Route each — call hooks_route with the description; capture the full response string.
Partition — group by whether the response contains the literal [AGENT_BOOSTER_AVAILABLE] (Tier 1) vs. not (Tier 2/3). Extract [TASK_MODEL_RECOMMENDATION] Use model="X" when present.
Compute spend — Tier 1 partition: $0. Tier 2/3 partition: per-task upper-bound from REFERENCE.md pricing × recommended model.

Tasks analyzed: 50
Tier 1 (booster): 18 (36%) — $0.00

[AGENT_BOOSTER_AVAILABLE] fires only when the upstream router populates routeResult.agentBoosterIntent.type (v3/@claude-flow/cli/src/mcp-tools/hooks-tools.ts:1228).

Route tasks through hooksroute, partition by Agent Booster availability, and report Tier 1 bypass utilization with $0 cost. Cost Booster Route is an agent skill from ruvnet/ruflo.
Cost Booster Route fits situations like: agent Workflows work in your project.
Run `npx skills add ruvnet/ruflo --skill cost-booster-route -a claude-code`. Or copy the skill folder (plugins/ruflo-cost-tracker/skills/cost-booster-route in ruvnet/ruflo) into .claude/skills/cost-booster-route in your project. Claude Code loads it when a task matches its description.
Run `npx skills add ruvnet/ruflo --skill cost-booster-route -a codex`. Or copy the skill folder (plugins/ruflo-cost-tracker/skills/cost-booster-route in ruvnet/ruflo) into .agents/skills/cost-booster-route in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ruvnet/ruflo --skill cost-booster-route -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cost-booster-route, .gemini/skills/cost-booster-route, .github/skills/cost-booster-route and .opencode/skills/cost-booster-route in your project.
SKILL.md names no scripts, command-line tools or credentials: Cost Booster Route is instructions for the agent only. Its frontmatter pre-approves these tools: mcp__plugin_ruflo-core_ruflo__hooks_route, mcp__plugin_ruflo-core_ruflo__memory_search, mcp__plugin_ruflo-core_ruflo__memory_list, Bash.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
Cost Booster Route is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 681 tokens (SKILL.md is roughly 2.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Cost Booster Route: Claude Code Agent Development (anthropics/claude-plugins-official, 38k stars), Copilot Session Failure Analysis (dotnet/maui, 23k stars), Mem0 CLI Memory Commands (mem0ai/mem0, 67k stars) and Create Agent (vectorize-io/hindsight, 48k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
ruvnet (a GitHub user) maintains it in ruvnet/ruflo, which has 74,222 GitHub stars. The repository holds 265 skills in this directory. The repository was last updated on October 10, 2026.
