What it does

Cost Estimation is an agent skill from Habitat-Thinking/ai-literacy-superpowers. Use when the user wants to estimate or predict the cost, token usage, or time of a task BEFORE it runs — "how much will this feature cost to build", "estimate the tokens for this spec", "what will this slice cost", "predict the agent-compute time before I commit" — produces a token + time estimate as a range with disclosed confidence, adding a dollar figure only when an observability/costs snapshot grounds it. The prospective sibling of cost-tracking, which records actual spend after the fact.

Its SKILL.md is about 5.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/estimate-record-format.md`).

It sits in AI & LLM Engineering, covering LLM cost and token optimization and Observability. The repository describes itself as: A set of Claude Code and GitHub Copilot plugins providing the AI Literacy framework's complete development workflow — harness engineering, agent orchestration, literate….

When your agent uses it

  • The user wants to estimate
  • Predict the cost
  • Time of a task BEFORE it runs — how much will this feature cost to build
  • Estimate the tokens for this spec

Example prompts

  • “how much will this feature cost to build”
  • “estimate the tokens for this spec”
  • “what will this slice cost”
  • “/cost-estimation”

Workflow steps

4 steps, taken from the first numbered list in SKILL.md.

  1. No snapshot exists — observability/costs/ is empty. → cost_usd
  2. Snapshot exists but the Model Breakdown is absent or too coarse
  3. Snapshot present but NO estimating-tier family resolves — after
  4. Snapshot present with ≥1 estimating-tier family resolving →

What it can do on your machine

Read from SKILL.md and the folder at commit 9d35995. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    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.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Cost Estimation loads about 5.4k tokens when it runs, and up to ~15k if it reads all its reference files. Until then it costs about 129 tokens; SKILL.md has 2,853 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~129
When it runs · the whole SKILL.md, loaded when a task matches
~5.4k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~15k

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.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 2,853 words (~5,374 tokens).

“Estimate, before work runs, the token usage and time a task will consume flowing through the orchestrator pipeline — and a dollar cost only when observed actuals exist to ground it.”

Cost Estimation is an agent skill from Habitat-Thinking/ai-literacy-superpowers. Use when the user wants to estimate or predict the cost, token usage, or time of a task BEFORE it runs — "how much will this feature cost to build", "estimate the tokens for this spec", "what will this slice cost", "predict the agent-compute time before I commit" — produces a token + time estimate as a range with disclosed confidence, adding a dollar figure only when an observability/costs snapshot grounds it.

When should I use Cost Estimation?

Cost Estimation fits situations like: the user wants to estimate; predict the cost; time of a task BEFORE it runs — how much will this feature cost to build; estimate the tokens for this spec.

How do I install Cost Estimation in Claude Code?

Run `npx skills add Habitat-Thinking/ai-literacy-superpowers --skill cost-estimation -a claude-code`. Or copy the skill folder (ai-literacy-superpowers/skills/cost-estimation in Habitat-Thinking/ai-literacy-superpowers) into .claude/skills/cost-estimation in your project. Claude Code loads it when a task matches its description.

How do I install Cost Estimation in Codex?

Run `npx skills add Habitat-Thinking/ai-literacy-superpowers --skill cost-estimation -a codex`. Or copy the skill folder (ai-literacy-superpowers/skills/cost-estimation in Habitat-Thinking/ai-literacy-superpowers) into .agents/skills/cost-estimation in your project. Codex loads it when a task matches its description.

Can I use Cost Estimation in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add Habitat-Thinking/ai-literacy-superpowers --skill cost-estimation -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-estimation, .gemini/skills/cost-estimation, .github/skills/cost-estimation and .opencode/skills/cost-estimation in your project.

What does Cost Estimation need to run?

SKILL.md names no scripts, command-line tools or credentials: Cost Estimation is instructions for the agent only.

Does Cost Estimation access the network?

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.

Is Cost Estimation safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Cost Estimation use?

Cost Estimation has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.

How many tokens does Cost Estimation use?

About 5.4k tokens (SKILL.md is roughly 21k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 10k tokens, read only when the agent opens those files.

What are the alternatives to Cost Estimation?

Skills that share tags, products or a category with Cost Estimation: Dt Obs Genai (Dynatrace/dynatrace-for-ai, 162 stars), AI Observability (omer-metin/skills-for-antigravity, 162 stars), Caveman Gateway Setup (JuliusBrussee/caveman, 111k stars) and Agent Kill Switch (vivekchand/clawmetry, 426 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
