Types

type Claude 

type Claude struct {
	// contains filtered or unexported fields
}

Claude wraps the Claude Code CLI as a provider.

func NewClaude 

func NewClaude() *Claude

NewClaude creates a Claude Code provider.

func NewClaudeWithPath 

func NewClaudeWithPath(dataPath string) *Claude

NewClaudeWithPath creates a Claude provider with a custom data path.

func (*Claude) Cost 

func (c *Claude) Cost() (inputCents, outputCents int64)

Cost returns Claude's token pricing (cents per 1K tokens). Based on Claude Opus 4 pricing.

func (*Claude) DataPath 

func (c *Claude) DataPath() string

DataPath returns the configured data path.

func (*Claude) Execute 

func (c *Claude) Execute(ctx context.Context, task Task) (Result, error)

Execute runs a task via Claude Code CLI.

func (*Claude) GetDailyStats 

func (c *Claude) GetDailyStats(date string) (*DailyStat, error)

GetDailyStats returns usage stats for a specific date.

func (*Claude) GetTodayUsage 

func (c *Claude) GetTodayUsage() (int64, error)

GetTodayUsage returns today's total token usage. Primary source: stats-cache.json (dailyModelTokens) — this is the metric the calibrator was trained against, so budget ratios stay consistent. Fallback: direct JSONL scanning if stats-cache is missing or has no entry for today. Note: JSONL input_tokens+output_tokens ≠ dailyModelTokens (Claude Code uses its own aggregation), so JSONL fallback is approximate.

func (*Claude) GetUsedPercent 

func (c *Claude) GetUsedPercent(mode string, weeklyBudget int64) (float64, error)

GetUsedPercent calculates the used percentage based on mode and budget. mode: "daily" or "weekly" weeklyBudget: total weekly token budget

func (*Claude) GetWeeklyUsage 

func (c *Claude) GetWeeklyUsage() (int64, error)

GetWeeklyUsage returns the last 7 days total token usage. Primary: stats-cache.json. Fallback: direct JSONL scanning.

func (*Claude) LastUsedPercentSource 

func (c *Claude) LastUsedPercentSource() string

LastUsedPercentSource reports where the last GetUsedPercent call sourced data.

func (*Claude) ListSessionFiles 

func (c *Claude) ListSessionFiles() ([]string, error)

ListSessionFiles finds all session JSONL files under the projects directory.

func (*Claude) Name 

func (c *Claude) Name() string

Name returns "claude".

func (*Claude) ParseStatsCache 

func (c *Claude) ParseStatsCache() (*StatsCache, error)

ParseStatsCache reads and parses the stats-cache.json file.

func (*Claude) ScanTodayTokens 

func (c *Claude) ScanTodayTokens() (int64, error)

ScanTodayTokens walks JSONL session files and sums input+output tokens for assistant messages timestamped today (local time). Files not modified today are skipped via mtime check for performance.

func (*Claude) ScanWeeklyTokens 

func (c *Claude) ScanWeeklyTokens() (int64, error)

ScanWeeklyTokens walks JSONL session files and sums input+output tokens for assistant messages timestamped within the last 7 days (local time).

type Codex 

type Codex struct {
	// contains filtered or unexported fields
}

Codex wraps the Codex CLI as a provider.

func NewCodex 

func NewCodex() *Codex

func (c *Codex) Cost() (inputCents, outputCents int64)

Cost returns Codex's token pricing (cents per 1K tokens). Based on GPT-4 pricing estimates.

func (*Codex) DataPath 

func (c *Codex) DataPath() string

func (*Codex) FindMostRecentSessionWithData 

func (c *Codex) FindMostRecentSessionWithData() (string, error)

func (*Codex) GetPrimaryUsedPercent 

func (c *Codex) GetPrimaryUsedPercent() (float64, error)

GetPrimaryUsedPercent returns the primary (daily) used_percent.

func (*Codex) GetRateLimits 

func (c *Codex) GetRateLimits() (*CodexRateLimits, error)

GetRateLimits retrieves the latest rate limits from the most recent session.

func (*Codex) GetResetTime 

func (c *Codex) GetResetTime(mode string) (time.Time, error)

GetResetTime returns the reset timestamp for the specified mode. mode: "daily" returns primary.resets_at, "weekly" returns secondary.resets_at.

func (*Codex) GetSecondaryUsedPercent 

func (c *Codex) GetSecondaryUsedPercent() (float64, error)

GetSecondaryUsedPercent returns the secondary (weekly) used_percent.

func (*Codex) GetTodayTokenUsage 

func (c *Codex) GetTodayTokenUsage() (*CodexTokenUsage, error)

GetTodayTokenUsage sums token usage across ALL sessions for today's date. Each session's cumulative total_token_usage is taken from the last token_count event in that file (since total_token_usage is cumulative within a session, the last event gives the session total).

func (*Codex) GetTodayTokens 

func (c *Codex) GetTodayTokens() (int64, error)

GetTodayTokens returns total tokens used across all sessions today. Satisfies the snapshots.CodexUsage interface.

func (*Codex) GetUsageBreakdown 

func (c *Codex) GetUsageBreakdown() UsageBreakdown

GetUsageBreakdown returns both rate limit percentages and local token counts so the budget display can show both authoritative and measured data.

func (*Codex) GetUsedPercent 

func (c *Codex) GetUsedPercent(mode string, weeklyBudget int64) (float64, error)

GetUsedPercent returns the used percentage based on mode. Uses Codex's own rate limit percentages as the authoritative source since our local billable token calculation may not match Codex's internal accounting (prompt caching, model launch bonuses, etc.). For daily mode: primary rate limit used_percent (5h window). For weekly mode: secondary rate limit used_percent. Falls back to token-based calculation only if rate limits are unavailable.

func (*Codex) GetWeeklyTokenUsage 

func (c *Codex) GetWeeklyTokenUsage() (*CodexTokenUsage, error)

GetWeeklyTokenUsage sums token usage across all sessions from the last 7 days.

func (*Codex) GetWeeklyTokens 

func (c *Codex) GetWeeklyTokens() (int64, error)

GetWeeklyTokens returns total tokens used across all sessions in the last 7 days. Satisfies the snapshots.CodexUsage interface.

func (*Codex) GetWindowMinutes 

func (c *Codex) GetWindowMinutes(mode string) (int64, error)

GetWindowMinutes returns the window duration for the specified mode.

func (*Codex) ListSessionFiles 

func (c *Codex) ListSessionFiles() ([]string, error)

func (*Codex) ListSessionFilesForDate 

func (c *Codex) ListSessionFilesForDate(t time.Time) ([]string, error)

ListSessionFilesForDate returns session files for a specific date.

func (*Codex) ListTodaySessionFiles 

func (c *Codex) ListTodaySessionFiles() ([]string, error)

ListTodaySessionFiles returns session files for today's date. Codex stores sessions at sessions/YYYY/MM/DD/*.jsonl.

func (*Codex) Name 

func (c *Codex) Name() string

Name returns "codex".

func (*Codex) ParseSessionJSONL 

func (c *Codex) ParseSessionJSONL(path string) (*CodexRateLimits, error)

func (*Codex) ParseSessionTokenUsage 

func (c *Codex) ParseSessionTokenUsage(path string) (*CodexTokenUsage, error)

ParseSessionTokenUsage reads a Codex session JSONL file and computes the session's billable token usage. Codex total_token_usage is cumulative within a session, so we take the delta between the first and last events. The result excludes cached input tokens since those don't count against rate limits. Returns nil if no token usage data is found (e.g. stub sessions).

RefreshRateLimits clears cached rate limits and re-reads from disk.
