A budget calculator that itemizes travel costs and presents savings strategies.

- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Budget Calculator is an agent skill from revfactory/harness-100. A budget calculator that itemizes travel costs and presents savings strategies. The 'budget-manager' agent must use this skill's cost reference tables, budget allocation formulas, and savings tips when calculating travel expenses and allocating budgets. Used for 'travel budget calculation', 'cost comparison', 'savings tips', etc. Itinerary design and local information are outside this skill's scope.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The licence is Apache-2.0.
Example prompts
- “budget-manager”
- “travel budget calculation”
- “cost comparison”
- “/budget-calculator”
What it can do on your machine
Read from SKILL.md and the folder at commit 8e8d35c. 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 (its code samples are markdown).
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
Budget Calculator loads about 1.2k tokens when it runs. Until then it costs about 105 tokens; SKILL.md has 277 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.
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.
