What it does

Cco Budget is an agent skill from egorfedorov/claude-context-optimizer. Configure token budget limits, auto-compact settings, and view current budget status (model-aware — Claude 5 lineup, Opus 5.5 default fallback, full 1M context at standard price)

Its SKILL.md is about 810 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 AI & LLM Engineering, covering LLM cost and token optimization and Context engineering. The repository describes itself as: Claude Code plugin that tracks token usage, identifies wasted context, and saves 30-50% on API costs. Heatmaps, ROI reports, budget alerts, efficiency scores, git-aware… The licence is MIT.

Requirements

Pre-approved tools (allowed-tools): Read

What it can do on your machine

Read from SKILL.md and the folder at commit f6f20ee. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves these tools, so the agent can use them without asking each time:
- Read
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 json).
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

Cco Budget loads about 808 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 354 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~47
When it runs · the whole SKILL.md, loaded when a task matches: ~808

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.

Context Budget Manager

Manage the token budget for Claude Code sessions. Model-aware — picks the right effective context window and prices per model. The session's REAL model is read from the transcript by the budget hook; config.model is only the fallback. Everything from Sonnet 4.6 up is 1M; Haiku 4.5 is 200K.

Parse $ARGUMENTS:

`status` (or no arguments)

Show current budget config + auto-compact settings: Read ~/.claude-context-optimizer/config.json and ~/.claude-context-optimizer/budget-config.json (either may be missing). If no config exists, show defaults (200K working budget on a 1M window, opus-5.5 fallback model, warn at 50/70/85/95%).

`set <tokens>`

Update the budget limit. Parse the token count (200K, 1M, 500000 all OK). Update ~/.claude-context-optimizer/config.json (the user approves the write):

json

{
  "budgetTokens": <parsed_number>,
  "warnAt": [50, 70, 85, 95],
  "autoCompactAt": 90,
  "model": "opus-5.5"
}

If budgetTokens exceeds the chosen model's context window, warn the user.

`model <name>`

Set the FALLBACK model for cost estimation (used only when a session's transcript has no model id yet). Supported keys:

haiku-4.5 (alias haiku) — $1/$5 per M, 200K
sonnet-4.6 (alias sonnet) — $3/$15 per M, 1M
sonnet-5 — $2/$10 per M, 1M
sonnet-5.5 — $2/$10 per M, 1M
opus-4.7 / opus-4.8 — $5/$25 per M, 1M
opus-5 (alias opus) — $5/$25 per M, 1M
opus-5.5 (default) — $4/$20 per M, 1M, cache reads at 0.05×
fable-5 — $10/$50 per M, 1M
fable-5.1 (alias fable) — $10/$50 per M, 1M, cache reads at 0.025× (vs 0.1× elsewhere)

opus-4.8-1m / opus-4.7-1m / opus-extended are back-compat aliases only — there is no 1M surcharge; the 1M window is standard at $5/$25.

Update the model field in config.json. When switching to a 1M-context model and the current budgetTokens is below 500K, ask if the user wants to bump it to 1M.

Show full SKILL.md (95 more words)Show less

`auto <on|off>`

Toggle auto-compact at thresholds (80% / 90%). Update ~/.claude-context-optimizer/budget-config.json:

auto on → autoCompactEnabled: true
auto off → autoCompactEnabled: false

Defaults if file missing:

json

{
  "autoCompactEnabled": true,
  "autoCompactThreshold": 80,
  "criticalThreshold": 90
}

Cost calculation

The budget monitor now estimates input + output tokens separately and uses the model's real input/output prices. Example: Edit with a 200-char new_string counts as ~54 output tokens, charged at the model's output rate.

Effective Budget Multiplier

At 50%+ budget usage, the monitor shows how much CCO multiplies your effective budget — e.g. "1.6x more effective" if Read Cache + file digests saved enough redundant reads to make your 200K context behave like ~320K.

Can I use Cco Budget 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 egorfedorov/claude-context-optimizer --skill cco-budget -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cco-budget, .gemini/skills/cco-budget, .github/skills/cco-budget and .opencode/skills/cco-budget in your project.

What does Cco Budget need to run?

SKILL.md names no scripts, command-line tools or credentials: Cco Budget is instructions for the agent only. Its frontmatter pre-approves these tools: Read.

Does Cco Budget 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.
