What it does
Agent Sources is an agent skill from ccusage/ccusage. Guides ccusage agent source formats. Use when checking where an agent stores its logs, how raw records map to tokens and models, how precomputed costs interact with cost modes, or which reports an agent supports.
Its SKILL.md is about 470 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Rust.
When your agent uses it
- Checking where an agent stores its logs
- How raw records map to tokens and models
- How precomputed costs interact with cost modes
- Which reports an agent supports
Example prompts
- “Use the agent-sources skill to guide ccusage agent source formats. An agent skill from ccusage/ccusage”
- “/agent-sources”
What it can do on your machine
Read from SKILL.md and the folder at commit 5ca8d8e. 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
Agent Sources loads about 469 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 209 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 209 words (~469 tokens).
“Every agent is an adapter crate in rust/adapters/ that turns one source's raw logs into the shared report shapes. ccusage aggregates all of them; ccusage scopes to one.”
