What it does
Blog Cost Charts is an agent skill from akitaonrails/my-skills. Generate dark-themed cost-vs-score bubble scatter charts and score/(costtime) value-ranking bar charts for a blog post comparing LLM benchmark results (or any dataset with a score/cost/time shape), in Portuguese and English, upload them to S3, and embed them in the Hugo article. Use when the user asks to add charts, graphs, or a visual comparison of models/options after a ranking table on akitaonrails.com.
Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including scripts (for example `README.md`, `scripts/config.example.json` and `scripts/make_charts.py`).
It sits in Writing & Content, covering File uploads and storage, Static sites and blogs and Blog and article writing. The repository describes itself as: akitaonrails' personal skills (not tailored for general usage).
When your agent uses it
- The user asks to add charts
- A visual comparison of models/options after a ranking table on akitaonrails.com
Example prompts
- “/blog-cost-charts”
Requirements
- Python 3
Workflow steps
7 steps, taken from the step headings in SKILL.md.
- Pick the dataset and scope
- Build the JSON config
- Tune label offsets to avoid overlap
- Generate
- Upload to S3 — do not skip this
- Embed in the article
- Rebuild and verify before committing
What it can do on your machine
Read from SKILL.md and the folder at commit 5763b9e. 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
Ships 2 files in scripts/ (Python), which the agent can run.
Shell commands in SKILL.md call:
python3awscurl
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
new-uploads-akitaonrails.s3.us-east-2.amazonaws.com
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
Blog Cost Charts loads about 2k tokens when it runs. Until then it costs about 107 tokens; SKILL.md has 872 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); the scripts in this folder are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 872 words (~2,032 tokens).
“You help turn a ranking table (score, cost, time, per item) into two companion charts for a blog post on this Hugo site: a cost-vs-score bubble scatter, and a score/(cost×time) value-ranking bar chart. Both are produced dark-themed, one PNG per…”
