budget-set

budget-set is a skill for Claude Code, Codex from hoangsonww/Claude-Code-Agent-Monitor. It costs 79 tokens per session (1,007 once invoked), scanned A, original, MIT.

A skill that turns a stated Claude Code budget into a dashboard alert rule. The rule watches cumulative tokens, which are the text units processed by the model.

In plain words
What is it for?
Use it to set weekly or monthly spending limits, translate them into token thresholds, and create or review the corresponding alert configuration.
Why use it?
It creates a measurable usage guardrail and checks existing rules first to avoid duplicating one.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

budget-set scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 13d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Budget Set

Help the user define a spend budget and turn it into a live cost guardrail on the Agent Monitor dashboard.

Input

The user provides: $ARGUMENTS

This is the budget to set — e.g. "$50/month", "$10/week", or "200000 tokens". If a period is omitted, treat it as a monthly budget and say so. If no number is given, read current spend first and propose a target.

Data Sources

Endpoint Returns
GET /api/pricing/cost { total_cost, breakdown: [{ model, input_tokens, output_tokens, cache_read_tokens, cache_write_tokens, cost, matched_rule }] } — current spend, used to size the budget and compute the blended $/token rate
GET /api/alerts/rules { rules: [{ id, name, rule_type, config, enabled, cooldown_seconds }] } — existing rules, so you don't create a duplicate guardrail
POST /api/alerts/rules Create a rule. Body: { name, rule_type, config, enabled?, cooldown_seconds? }. Returns { rule }

How a budget becomes a rule

The dashboard's alerting engine fires on tokens, not dollars. The spend-relevant rule type is token_threshold, whose config is { total_tokens } — it fires when a session's cumulative tokens (input + output + cache_read + cache_write) cross the threshold. To turn a dollar budget into a token ceiling:

blended_rate_per_token = total_cost / total_tokens          # from /api/pricing/cost
token_ceiling          = budget_dollars / blended_rate_per_token

Compute total_tokens by summing the four token columns across the cost breakdown.

Rule fields explained

Field Meaning
name Human label shown in the alert feed (e.g. "Monthly $50 budget"). Required, non-empty.
rule_type "token_threshold" for a spend guardrail. (Other types: event_pattern, inactivity, status_duration — not spend-related.)
config.total_tokens Positive integer token ceiling. A session crossing it fires the alert. Derive from the dollar budget as above.
enabled true to arm immediately (default), false to stage it.
cooldown_seconds Minimum seconds between re-fires for the same scope. Default 300. Raise it (e.g. 3600) so a single overspending session doesn't spam the feed.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
