Follow-ups to #710, completing issue #708's second ask plus the two review
notes:
- export: new records.csv with one row per call incl. subagentType and
model; sessions.csv gains both fields APPENDED after all legacy columns
so by-index consumers are unaffected; JSON fields additive; formula-
injection escaping preserved
- models --by-agent: the main-session bucket sentinel becomes '(main)' -
agentType is free-form text, so a real subagent literally named 'main'
no longer merges into the main bucket (test-pinned across all formats)
- README: note that the --min-cost 0.01 default can hide sub-cent agent
buckets; --min-cost 0 shows the complete agent inventory
Orchestrator setups pin different agents to different models (planner on
Opus, implementers on Sonnet, scouts on Haiku). The dashboard shows
"Skills & Agents" and "By Model" as separate panels, so there was no way
to see which agent drove which model's spend, or catch an agent that
silently switched models. `codeburn models --by-agent` closes that gap:
one row per (provider, model, agent), mirroring the existing --by-task
pattern across the table, markdown, CSV, and JSON renderers.
The agent label comes from each Claude subagent transcript session's own
agentType crossed with that session's model calls, aggregated through the
same assistantCalls path --by-task uses (not modelBreakdown), so cache-tier
dedup, savings, and Codex-credit logic all carry over unchanged. This is
the authoritative pairing; main-session subagentTypes spawn markers are
deliberately not joined to models, since a spawn marker names an agent but
not the model that agent actually ran on.
Ordinary main sessions (no agentType) and every non-Claude provider have
no agent, so their spend buckets under the label "main" rather than being
dropped or fabricated into a false agent. --by-agent is mutually exclusive
with --by-task; passing both errors politely.
Exposing subagentType + per-record model on `codeburn export` (so users
can build custom crosses over the export) is a separate follow-up and is
intentionally out of scope here.
* feat(codex): compute Codex credit usage (#408, #495)
Codex/ChatGPT subscription users consume credits, a unit separate from API
dollars: usage is billed as credits-per-million-tokens at per-model rates that
differ from the API USD pricing CodeBurn uses for cost. So the reported dollar
cost does not match what credits actually consume.
Add a credit engine sourced from the official Codex credit rates
(developers.openai.com/codex/pricing): GPT-5.5 125/12.5/750, GPT-5.4
62.5/6.25/375, GPT-5.4 mini 18.75/1.875/113 credits per 1M input/cached/output
tokens. Surface per-model credit usage in `codeburn models` JSON output
(credits field; null for non-Codex or unknown models). models-report already
folds reasoning into output and keeps non-cached input + cached-read separately,
which is exactly what the credit rates expect, so the figure is exact.
Engine + computation are unit-tested. UI display surfaces (the models table,
the TUI dashboard, the menubar "credits" view) are intentionally left for a
follow-up so the display choice can be decided.
* feat(menubar): opt-in Codex credits display metric (#408, #495)
Surface Codex credit usage in the menubar as a selectable metric, without
changing the default. Cost ($) stays the default in both the menubar and the
CLI; credits only appear when explicitly chosen.
- TS: buildMenubarPayloadForRange computes the period's Codex credits (via the
tested aggregateModels, so reasoning/cached are handled) and exposes
current.codexCredits in the menubar JSON.
- Swift: new DisplayMetric.credits, a "Credits (Codex)" option in the metric
picker, decodes codexCredits, and renders it in the menu-bar title. Default
metric remains .cost.
Resolves conflicts from the post-PR refactor that moved buildPeriodData,
hydrateCache, and the menubar payload builder out of main.ts into
usage-aggregator.ts. The PR's savings additions to those functions are
re-homed there; config.ts keeps both new fields; parser.ts keeps both imports;
redact.ts session details carry savingsUSD.
cacheReadInputTokens (Anthropic) and cachedInputTokens (OpenAI) name the
same tokens. ~11 providers populate both with the same value, so summing
them doubled the cache-read token figure in the models report. Take the
max instead. Cost is unaffected (calculateCost never used the sum).
Add a new `localModelSavings` config and `codeburn model-savings` CLI
that maps a local-model name (e.g. llama3.1:8b) to a paid baseline
(e.g. gpt-4o). The local call still costs $0; the new `savingsUSD`
field tracks the counterfactual spend avoided by running locally and
is reported separately from `costUSD` everywhere a number is shown.
* Parser normalization (`applyLocalModelSavings`) runs on Claude
parse, direct provider calls, and the cached-call path. It forces
`costUSD` to 0 and attaches `savingsUSD` + `savingsBaselineModel`
+ `isLocalSavings` on the `ParsedApiCall`. Local-savings wins for
actual cost even when the same model is also in `modelAliases`.
* Session, project, day, model, category, activity, skill, and
subagent rollups all carry `savingsUSD` alongside `costUSD`.
* `status --format json` adds `today.savings` and `month.savings`.
* `status --format menubar-json` adds a `current.localModelSavings`
block (totalUSD, calls, byModel, byProvider) plus savings on
topModels, topProjects, topSessions, topActivities, and history
daily entries. Schema fields default-decode for backward compat.
* `report --format json` adds savings across overview/daily/
projects/models/activities/skills/subagents/topSessions, with
the active paid baseline name on each model row.
* `models` command gains a `Saved` column on table/markdown/CSV
and a `savingsUSD`/`savingsBaselineModel` pair in JSON. Default
`--min-cost 0.01` filter now ORs in `savingsUSD >= minCost` so
local models with $0 actual cost but >0 savings still surface.
* CSV/JSON exports add a `Saved (CODE)` column on summary/daily/
models/projects/sessions.
* Dashboard TUI shows a green 'saved $X by local models' footer
line in the overview when any savings are present.
* macOS Swift payload gains a `LocalModelSavings` Codable block
and savings fields on every model/activity/session/daily
struct. Hero shows a green leaf 'Saved $X' caption, models
section gets a green `Saved` column. `swift build` clean.
* GNOME indicator adds 'saved $X' to the hero meta line and a
`codeburn-model-saved` column to the model row.
* Daily cache schema bumped to v8 (`savingsUSD` on day/model/
category/provider). `savingsConfigHash` invalidates the cache
when the user changes their baseline mapping so historical
saved-spend numbers never lie about a stale baseline.
* Defensive `Object.hasOwn` lookup in `getLocalSavingsBaseline`
blocks the prototype-pollution test that previously surfaced via
the savings path with a hostile `__proto__` model name.
* New tests (5 files, 25 tests, 549 lines) cover pricing helpers,
end-to-end parser normalization, day aggregator savings,
menubar payload savings, CLI set/list/remove, and
daily-cache hash invalidation. Existing tests for daily-cache
/ day-aggregator / models-report updated for the new fields.
Full vitest suite: 1028/1028 passing across 73 test files.
`tsc --noEmit` clean. `npm run build` clean.
(Note: `mac/Tests` has a pre-existing `no such module 'Testing'`
environment error on the installed Swift toolchain, confirmed
on `main` before this PR; not caused by these changes.)
A single dense table of every (provider, model) you have used in the
selected period, sorted by cost. Inspired by tokscale's per-model
output and ccusage's responsive cli-table3 layout, ported to plain
Node with no new runtime dependency.
Default view: one row per (provider, model) with a Top Task cell
showing the dominant task category and its cost share, e.g.
`Coding (42%)`.
`--by-task` explodes each model into one row per task type, with
provider/model cells blanked on subsequent rows of the same group
and a horizontal divider between groups so the sections read as
distinct units.
Output formats: table (Unicode box-drawn, default), markdown
(GitHub-flavored, copy-paste friendly), json, csv.
Filters: --period (today/week/30days/month/all, default 30days),
--from/--to, --provider, --task, --top, --min-cost, --no-totals.
The table renderer auto-sizes every column to its content (no fixed
widths leaving trailing whitespace) and drops cache columns as a
pair when the terminal is narrow, then input/output, then top-task,
in that order. Provider, model, total, and cost stay regardless.
Visible-width math uses strip-ansi (already a dependency) so styled
cells pad correctly. Cyan headers, yellow totals, dim provider name.
The aggregator walks every parsed turn and attributes each
assistant call to its (provider, model, task) bucket, computing
real input / output / cache_write / cache_read tokens and cost.
Output tokens include reasoning. Cached input tokens are folded
into cache_read so the column matches what users intuitively expect.
19 fixture-based tests cover aggregation correctness, byTask
grouping, taskFilter, topN/minCost filters, reasoning-as-output,
all four renderers (table/markdown/json/csv), narrow-terminal
column dropping, CSV/markdown escaping, totals row toggle, and
visible-width math under styled cells.
