feat(experiments): per-role metric columns in list and open-ended date filters (FT-2332) - #8
Conversation
…e filters (FT-2332) - Send an empty bound for one-sided --*-after/--*-before ranges; the API reads 0 as epoch 0, so --started-after alone returned no results. - Add secondary_metrics, guardrail_metrics and exploratory_metrics as --show/--show-only columns on experiments list. - Build table/markdown/plain columns from the union of row keys so extra columns missing from the first row are no longer dropped.

Experiment summaries can display requested metric-role columns. Table, plain, and Markdown output use the union of keys across rows. The README example adds a recent-start filter and limits displayed fields. The package version changes to 1.16.0.

Metric role columns now return arrays, so JSON/YAML get real lists and table/vertical output stacks multiple metrics instead of comma-joining them into very wide cells. Plain and markdown stay comma-joined. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

COMMENT - The supplied head passes validation with one non-blocking performance nit; the PR moved during review, so approval is withheld.
Reviewed head: 395612be87057d201b0c94d8f0ac3c3ace31b29e. Base and merge-base: 529196deca9e8ff1464365a03af545acbc41569e.
The intended changes are open-ended experiment date ranges, opt-in per-role metric columns, union-key table/markdown/plain output, and release 1.16.0. I traced the registered experiment-list workflow, raw and dot-path alternatives, get/diff summary reuse, and shared formatter consumers. No material functional blocker was established at the supplied head.
Verification
- Installed the frozen Bun lockfile with lifecycle scripts disabled (avoiding the repository's Git-config prepare script).
npm run test:run: 216 files passed, 1 skipped; 2,748 tests passed, 4 skipped. An initial 120-second invocation timed out; the complete rerun passed in 250 seconds.npm run typecheck,npm run lint,bunx prettier --check 'src/**/*.ts', andnpm run build: all passed.- Executed a compiled core-list → API-request → metric-projection → plain-output harness, including preservation of raw data and metric dot paths.
- Reverted the three changed production files to base in a separate scratch worktree, leaving tests unmodified: 12 targeted assertions failed, covering changed date encoding, role columns, and table/markdown/plain output.
- Exact-head GitHub CI succeeded: lint/typecheck, tests with coverage on Node 20 and 22, and build.
- Enumerated and inspected all 10 content writes introduced by the PR commits, including the earlier formatter-test blob. No credential or extraneous artifact found.
Scope limitation
The final head check found 794ac765fcf6af236b4a8c523c4ef3ee9e6de802, with the base unchanged. Its delta changes metric projections to arrays and shared table/vertical array rendering. This review reports the explicitly supplied head, not merge readiness of that newer revision; the new behavior requires follow-up validation before approval. This is not a CI deferral. Live API behavior was not independently repeated; the author's test-1/latam observations are supporting evidence, while local checks verified outgoing range encoding. No live credentials, cloud queries, deployment commands, or browser authentication were used.
Review census
Passes (non-blocking): run: core runtime/API/error paths (three executable files changed; independent read-only pass), tests/CI/packaging (four test files and release version changed), cross-cutting simplicity (local audit of the small source delta), comment hygiene, diff composition | not run: deployment/operations/observability (no deployment or emitted telemetry changes), shared frontend components (no frontend source), behaviour-bearing data/policy (no runtime policy/configuration change beyond the package version reviewed under packaging).
Comment hygiene (non-blocking): 8 comment / 143 code lines, ratio ~1:17.9, none flagged
threshold T=5; restatements counted: no (10 × C < E)
The added comments record the API's empty-bound semantics, metric-role schema semantics, and the optional-field alignment constraint.
Diff composition (non-blocking): every file is required for the change; none flagged
Simplifications (non-blocking): none
The inline array-copy observation is optional and does not block either revision. No prior review was dismissed. Temporary detached worktrees were cleaned up; the PR source branch was not modified.

APPROVED - The current head passes local validation and exact-head CI; no material blocker remains, and the previous performance nit is fixed.
Reviewed head: 07c197f01d5f1dcd68c085fa877d31672d78fc4a. Base and merge-base: 529196deca9e8ff1464365a03af545acbc41569e. This incorporates both pushes since the prior review at 395612be87057d201b0c94d8f0ac3c3ace31b29e, including 794ac765fcf6af236b4a8c523c4ef3ee9e6de802.
Scope and outcome
Reviewed open-ended experiment date filters, opt-in metric-role columns, union-key output, shared array rendering, and the 1.16.0 release bump. The newer commit explicitly intends arrays in JSON/YAML and one item per line in table/vertical output; plain/markdown remain comma-separated. The shared array-rendering change also applies to other command results and raw/dot-path values, not only metric columns. I traced those consumers and exercised representative string/object arrays. Raw experiment data and dot-path projections remain available.
The earlier repeated-copy nit is addressed: metric grouping now appends in place, preserving order with linear work. No new inline finding, failed material check, or material unresolved context remains.
Verification
bun install --frozen-lockfile --ignore-scriptsused the repository lockfile without invoking the Git-config prepare hook.npm run test:run: 216 files passed, 1 skipped; 2,750 tests passed, 4 skipped.npm run typecheck,npm run lint,bunx prettier --check 'src/**/*.ts', andnpm run build: all passed at this head.- Compiled core-list → API-request → role-projection → output harness passed: missing date upper bound, role arrays, empty roles, JSON/YAML lists, stacked table cells, vertical continuation indentation, comma-joined plain/markdown, raw data, dot paths, and shared object-array formatting.
- Scratch revert checks with tests unmodified: restoring pre-array summary behavior made four role-array assertions fail; restoring pre-array formatter behavior made the new table-rendering test fail. Earlier cumulative date/union-key revert evidence remains applicable to unchanged hunks.
- Exact-head GitHub CI passed lint/typecheck, tests with coverage on Node 20 and 22, and build.
- Re-ran introduced-blob enumeration and inspected the five additional content writes alongside the ten previously audited writes: no credential or extraneous artifact found.
Live API calls were not repeated; the author's test-1/latam observations support server interpretation of empty bounds, while automated checks verify the actual outgoing requests. No cloud queries, browser authentication, deployments, or source-branch changes were performed.

Summary
You can now list recent experiments along with their metric roles:
abs experiments list --started-after "3 months ago" \ --show-only id name primary_metric secondary_metrics guardrail_metrics exploratory_metricsThis PR has three fixes:
--started-after Xon its own sentstarted_at=X,0, and the API reads0as epoch 0, so the range was empty. A missing bound is now sent empty (X,), which the API treats as open-ended.created_*andstopped_*had the same bug. Verified against test-1 (1783714345066,→ 31 results,…,0→ 0) and latam.experiments listnow supports--show/--show-onlywithsecondary_metrics,guardrail_metricsandexploratory_metrics. Each is a comma-joined list of metric names, split by thetypeof each entry insecondary_metrics. The names match case-insensitively.Bumps the version to 1.16.0.
Behavior change
--show secondary_metricsonexperiments listused to dump the rawsecondary_metricsarray, which mixes all roles. It now returns only the names of secondary-role metrics, matching whatexperiments getalready shows. The raw data is still available through--rawor dot paths such as--show secondary_metrics.metric.name secondary_metrics.type.Test plan
