Fixes - Moda

Fixes pair a candidate change with a replay-gate verdict on held-out production evidence. These endpoints mirror the Fixes dashboard.

Base URL and authentication

Unlike the rest of the Data API, the fix routes are tenant-scoped and live under the control-plane base:

https://moda.dev/api/tenants/:tenantId/...

They accept the same x-api-key header as the Data API (a dashboard session also works). Reads require workspace membership; every mutation (POST) requires the admin role. Responses use camelCase field names — except the fix packet, which is snake_case by design (it is an agent-facing document).

Endpoints

Endpoint	Description
`POST /tenants/:tenantId/problems/:problemId/fixes`	Draft a fix from a problem.
`GET /tenants/:tenantId/problems/:problemId/fixes`	All fixes for one problem.
`POST /tenants/:tenantId/fixes/draft-batch`	Campaign mode: batch-draft fixes for the top-ranked problems.
`GET /tenants/:tenantId/fixes`	The ranked fix queue.
`GET /tenants/:tenantId/fixes/:fixId`	One fix, including `gateResult`.
`GET /tenants/:tenantId/fixes/:fixId/packet`	The `moda.fix_packet.v1` agent packet.
`POST /tenants/:tenantId/fixes/:fixId/advance`	Perform exactly one pipeline step.
`POST /tenants/:tenantId/fixes/:fixId/verify`	Re-gate the candidate (optionally with uploaded content).
`POST /tenants/:tenantId/fixes/:fixId/submit`	Deliver: open a draft PR or record a local branch.
`POST /tenants/:tenantId/fixes/:fixId/mark-applied`	Confirm a candidate applied outside GitHub (no PR).
`POST /tenants/:tenantId/fixes/:fixId/dismiss`	Reject the fix with a reason.

The Fix object

Every fix endpoint (except the packet) returns or embeds this shape:

Field	Type	Meaning
`id`	string	Fix ID — use it in every `/fixes/:fixId` route.
`shortRef`	string	8-character upper base36 alias; renders as `MODA-FIX-<SHORTREF>` and is the PR magic word.
`tenantId` / `problemId`	string	Owning tenant and the problem (UUID) the fix was drafted from.
`rubricVersion` / `attemptNo`	integer	The problem definition version the fix targets, and the attempt counter within it.
`fixType`	string	`PROMPT`, `TOOL_SCHEMA`, `SKILL`, `GUARDRAIL`, or `UNROUTED`. `PROMPT` proposes a prompt revision, `TOOL_SCHEMA` a rewrite of one tool’s description, `SKILL` a drafted SKILL.md; `GUARDRAIL` and `UNROUTED` are packet-only (diagnosis).
`status` / `statusReason`	string	Pipeline status (see below) and a human-readable reason.
`targetArtifactKey` / `targetSourcePath` / `routeConfidence`	string / string / number	The routed harness artifact, its repo-relative source path, and routing confidence. `null` when unrouted.
`promptId` / `baselineVersionId`	string	The registry prompt and the prod-labeled version pinned as the gate baseline.
`replaySetId` / `repairCaseIds` / `holdoutCaseIds`	string / string[] / string[]	The frozen evalset and its repair/holdout split. The holdout is never given to a proposer.
`candidateRef`	object	Typed by candidate kind — see Candidate refs.
`gateRunId` / `controlRunId`	string	The gate (baseline vs. candidate) and control (baseline vs. baseline) replay run IDs.
`gateResult`	object	The verdict plus its baseline-fidelity label — see Gate result.
`deliveryChannel` / `prUrl` / `prBranch`	string	`pr` or `local`, plus the PR URL and branch once delivered.
`fixRef`	object	Confirmation provenance: `{ prUrl, mergeCommit, promptVersionId, mergedAt }` from the merge webhook, or `{ appliedNote, appliedAt, promptVersionId }` from `mark-applied`.
`problemRank`	number	The problem’s current rank (list decoration; `null` when unavailable).
`createdAt` / `updatedAt`	string	Timestamps.

Candidate refs

candidateRef carries the proposed candidate, discriminated by kind:

Kind	Shape	Meaning
prompt (no `kind` field)	`{ promptVersionId, changelog?, risks? }`	A registered prompt version (`PROMPT` fixes). A locally verified candidate records `promptVersionId: ""` with a `contentSha256`.
`tool_description`	`{ kind, toolName, currentDescription, currentDescriptionSource, proposedDescription, paramNotes, rationale }`	A rewrite of one tool’s description (`TOOL_SCHEMA` fixes). `currentDescriptionSource` is `tool_definitions` when the tenant has a registered tool definition, or `receipt_shapes` when the current description was reconstructed from receipts.
`skill`	`{ kind, skillName, skillMd, skillId? }`	A complete drafted SKILL.md (`SKILL` fixes). The gate registers a content-addressed copy of the body automatically, so inline drafts gate too; `skillId` appears once the skill is separately registered with the Moda skill harness.
`skill_edit`	`{ kind, skillKey, skillId, skillName, currentSkillMd, proposedSkillMd, changeSummary, source }`	A minimal edit to an existing skill (`SKILL` fixes, when the proposer matches the failure to a skill you already run). `source` is `synced` (the current body came from your synced registry; `skillId` is the synced-registry id) or `observed` (the current body was recovered from production receipts; `skillId` is `null`). Edits gate current-vs-proposed — the verdict’s fidelity label records the provenance — and are delivered via packet or mark-applied.

Statuses

DRAFT, SCOPING, NO_EVIDENCE, BLOCKED_COVERAGE, UNROUTED, PROPOSING, NO_HEADROOM, PROPOSED, GATING, GATE_FAILED, GATE_INCONCLUSIVE, VERIFIED, PR_OPEN, APPLIED_LOCALLY, HANDED_OFF, SHIPPED, CONFIRMING, HELD, REGRESSED, REJECTED, SUPERSEDED, ABANDONED. The dashboard lifecycle table explains each stage.

Gate result

gateResult is set once a gate finishes:

{
  "repair": { "baseline": 38, "candidate": 51, "n": 62 },
  "holdout": { "baseline": 11, "candidate": 16, "n": 21, "wins": 6, "losses": 1 },
  "noiseFloor": 1,
  "abstained": 2,
  "verdict": "pass",
  "reason": "holdout wins 6 − losses 1 ≥ max(2, noise floor 1 + 1) and losses within noise floor",
  "baselineFidelity": { "prompt": "tenant", "skills": "none" },
  "counterfactual": {
    "verdict": "pass",
    "wins": 4,
    "losses": 1,
    "informative": 6,
    "anchors": 12,
    "abstained": 2,
    "reason": "counterfactual gate: wins 4 − losses 1 ≥ max(2, ceil(0.2 × 6)) on 6 informative anchors"
  },
  "completedAt": "2026-09-30T21:14:05.123Z"
}

completedAt is when the verdict was written. Verdicts written before this field existed don’t have it. The verdict reads holdout cases only. pass requires wins − losses ≥ max(2, noiseFloor + 1), losses ≤ noiseFloor, and abstained ≤ 30% of the holdout; more than 30% abstained is inconclusive (never a pass); anything else is fail. verdict values are exactly pass / fail / inconclusive. While the gate is enqueued (GATING), gateResult may instead hold a pending marker — { "pending": true, "baselineFidelity": { ... } } — recorded at enqueue time, before any verdict exists. Treat it as “no verdict yet”; the display surfaces render no gate view for it. The pending marker may also carry enqueue-time counterfactual context (for example the anchors selected) with no counterfactual.verdict — the surfaces render no counterfactual copy for that either.

Counterfactual gate (gateResult.counterfactual)

gateResult.counterfactual is the counterfactual-anchored gate’s verdict: the fix replayed against recorded production failures from holdout traces, two arms per anchor — a control arm without the fix and a candidate arm with it. The block is optional: comparison-only verdicts omit it entirely, and every comparison field above is unchanged whether or not it is present.

Field	Type	Meaning
`verdict`	string	`pass` / `fail` / `inconclusive` — the same closed set as the comparison verdict.
`anchors`	integer	Fork points replayed — failure-anchored user turns from holdout traces only (the proposer never saw them).
`informative`	integer	Anchors whose control arm still reproduced the recorded failure. Only these can score: a win requires the control arm to recur.
`wins`	integer	Prevented failures: control recurred, candidate avoided.
`losses`	integer	Regressions: candidate recurred where control avoided.
`abstained`	integer	Anchors where either arm abstained (world gap or judge abstention) — excluded from scoring, never hidden.
`reason`	string	Human-readable verdict math, naming the counterfactual gate.

The verdict math: pass iff wins − losses ≥ max(2, ceil(0.2 × informative)) and informative ≥ 3 and abstained ≤ 30% of anchors; inconclusive when informative < 3 or abstained exceeds 30% (no informative anchors is inconclusive, never a pass); anything else is fail. A counterfactual pass can upgrade a comparison GATE_FAILED/GATE_INCONCLUSIVE fix to VERIFIED — but only when the comparison gate did not fail with losses beyond its noise floor. Overall: pass if either gate passes and neither gate has losses above noise; otherwise the stricter of the two verdicts stands. The top-level reason always names which gate produced the verdict. Display surfaces render the block as prevented {wins} of {informative} replayed production failures (control still failed in {informative}; regressions {losses}) — alongside, never instead of, the comparison verdict. In the fix packet the block rides under the snake_case key counterfactual.

Verdict fidelity

baselineFidelity labels what the baseline arm was made of, so a verdict never claims more than the gate actually compared. It is optional: verdicts produced before fidelity labeling omit it. baselineFidelity.prompt — the prompt pinned in both arms:

Tier	Value	Meaning
Tenant prompt baseline	`tenant`	Both arms replay the tenant’s own managed prompt.
Standard-agent baseline	`generic`	No managed prompt was available; both arms pin Moda’s fixed, versioned, neutral standard-agent prompt.

baselineFidelity.skills — where the baseline arm’s skill content came from:

Value	Meaning
`none`	No baseline skill — the candidate artifact (tool description or net-new skill) is the only delta between arms.
`synced`	A skill edit gated against the current body from your synced skill registry.
`observed`	A skill edit gated against a current body recovered from production receipts (the skill was never synced).

Fidelity is always shown next to Verified. Every surface that renders the verdict — the dashboard badges, the CLI summaries, and the packet — qualifies it: Verified — tenant prompt baseline or Verified — standard-agent baseline, with · skill recovered from production receipts appended when skills is observed. A generic-prompt or recovered-skill verdict never renders as plain “Verified”.

POST /tenants/:tenantId/problems/:problemId/fixes

Drafts a fix. Creation is idempotent while a fix is active: drafting again for the same problem returns the existing active fix instead of forking the pipeline. The new fix rests at DRAFT — drive it with advance.

string

default:"auto"

auto routes from evidence; prompt considers only the prompt route.

A malformed (non-UUID) problem ID returns 400; an unknown problem returns 404. A merged-away problem ID is folded to its survivor, like the problem endpoints.

POST /tenants/:tenantId/fixes/draft-batch

Campaign mode: batch-drafts fixes for the tenant’s top-ranked fixable problems in one call — what the dashboard’s Draft fixes for top problems button calls. Problems are scanned in rank order; each is drafted through the same guarded creation path as the single-problem route above, or skipped with a reason when it already has an active fix, its latest lifecycle is not open/reopened, or it aliases a problem already handled in the batch. Creation only — nothing advances server-side; drive the drafted fixes with advance.

integer

default:"10"

How many fixes to draft, 1–25 (400 beyond the cap). The 25 cap is an LLM spend guard, not a paging nicety: every drafted fix burns distillation + propose budget once driven, so batches are deliberately small — run another after the first lands.

drafted entries are full Fix objects decorated with the rank the batch ranked on. Per-problem failures never abort the batch — they land in skipped with the error message as the reason.

GET /tenants/:tenantId/fixes

The ranked queue: fixes ordered by their problem’s rank (descending), then recency. Also available per problem at GET /tenants/:tenantId/problems/:problemId/fixes (returns { "fixes": [...] } without pagination).

Filter to one status. An unknown status returns 400.

1–100.

Opaque cursor from a previous page’s pagination.next_cursor.

  ],
  "pagination": { "limit": 10, "has_more": false, "next_cursor": null, "scan_truncated": false }
}

The ranked list scans a bounded window (500 fixes) before ranking and paging, so has_more goes false at the end of that window even when more fixes exist behind it. scan_truncated: true says the tail was cut — page with a status filter to reach the rest rather than treating an empty next_cursor as the whole queue.

Reading a fix reconciles its confirmation state lazily: SHIPPED/CONFIRMING fixes are checked against the problem’s lifecycle on every read, so a reopen or 14 clean monitoring days surface as REGRESSED/HELD without a background job.

GET /tenants/:tenantId/fixes/:fixId/packet

The compact agent packet — moda.fix_packet.v1. Every fix has one, including diagnosis-only fixes without a candidate. Quoted evidence in the packet is neutralized as untrusted data before it reaches an agent.

}

target keys, candidate, and evidence entries are omitted when unknown (for example an UNROUTED fix has only fix_type in target and no candidate). Typed candidates ride the packet under their own keys (injection-screened at propose time and scrubbed again on the way out):

candidate_tool (TOOL_SCHEMA fixes) — { tool_name, current_description, current_description_source, proposed_description, param_notes, rationale }: the tool-description diff to apply in your own tool definition.
candidate_skill (SKILL fixes) — { skill_name, skill_md }: the complete drafted SKILL.md to install in your agent.
candidate_skill_edit (SKILL fixes amending an existing synced skill) — { skill_key, skill_name, current_skill_md, proposed_skill_md, change_summary }: the current-vs-proposed SKILL.md edit to apply to the skill already in your repo.

Apply either one in your stack, then confirm with mark-applied — no GitHub integration required.

POST /tenants/:tenantId/fixes/:fixId/advance

Performs exactly one idempotent pipeline step and returns the updated fix. The backend runs no background jobs — clients drive the pipeline by calling advance in a loop (this is what the dashboard polling loop does). Steps are claimed optimistically, so concurrent advances never double-run a stage; the loser returns the current row untouched.

Current status	What one advance does
`DRAFT` / `SCOPING`	Scopes evidence, builds the frozen replay set, routes the target (`PROMPT`, `TOOL_SCHEMA`, or `SKILL`; see routing).
`PROPOSING`	Generates the candidate: a registered prompt version (`PROMPT`), a tool-description rewrite (`TOOL_SCHEMA`), or a drafted SKILL.md (`SKILL`).
`PROPOSED`	Enqueues the gate and control replay runs (status → `GATING`), recording the pending marker with the gate’s fidelity label. Exception: a `SKILL` candidate without gateable content rests at `PROPOSED` with the gate pending — deliverable via packet or mark-applied.
`GATING`	Polls the runs; when both finish, computes the verdict and lands `VERIFIED`, `GATE_FAILED`, or `GATE_INCONCLUSIVE`.
`SHIPPED` / `CONFIRMING`	Reconciles confirmation against the problem lifecycle.
anything else	No-op — resting and terminal fixes return unchanged. Delivery goes through `submit`; confirmation through the merge.

  -H "x-api-key: YOUR_MODA_API_KEY"

Routing

Scoping picks the target from the problem’s evidence conversations, in order:

PROMPT when at least 60% of evidence conversations carry the same registry prompt version. With fixType: "prompt" and no dominant version the fix lands UNROUTED; when no conversation carries a prompt version at all, the reason explains how to stamp one (prompt attribution).
SKILL when the laziness or emotion signal family owns at least half the evidence anchors.
TOOL_SCHEMA when one tool’s call-side failures (bad arguments, unmet preconditions) appear in at least 40% of evidence conversations, and in at least 3 of them. Conversations are counted, not anchors, so one noisy trace cannot route a problem. routeConfidence is that conversation share.
UNROUTED (harness code) when runtime failures (timeouts, connection resets, upstream 5xx, 401/403, rate limits) appear in at least 60% of the conversations with tool failures, in at least 40% of evidence conversations, and in at least 3 of them. No prompt, tool-description, or skill edit fixes these; the statusReason starts with harness code: and names the tools.
SKILL otherwise, as a behavior-level fix. The statusReason says which tool was considered and why it was not routed.

POST /tenants/:tenantId/fixes/:fixId/verify

Re-gates the fix: enqueues fresh gate and control runs and returns the pinned gate run ID. With candidateContent this gates uploaded local content instead of the stored candidate. Then drive advance until the fix leaves GATING. For TOOL_SCHEMA and SKILL fixes, both gate arms pin the same prompt so the candidate artifact is the only delta between arms: the tenant’s managed prompt when one exists (baselineFidelity.prompt: "tenant"), or Moda’s fixed standard-agent baseline prompt in both arms otherwise ("generic"). Skill candidates — net-new drafts and edits alike — are registered as content-addressed gate skills automatically: the candidate body rides the proposed arm, and a skill_edit pins the current body (synced or receipt-recovered) in the baseline arm. Only a candidate without gateable content rests at PROPOSED with the gate pending. The resulting verdict always carries its fidelity label.

string

Optional candidate content, 40–200,000 characters, PROMPT fixes only (400 for other fix types). Omitted = re-gate the stored candidate version. Uploaded content is recorded by hash (candidateRef.contentSha256), not registered as a prompt version.

curl -X POST "https://moda.dev/api/tenants/1f7c9a2e-4b3d-4c8e-9a1b-2d3e4f5a6b7c/fixes/cme9y2k1q0001l708g6p4xw3v/verify" \

{ "gateRunId": "run_7b1c9e2f4a5d6081" }

Allowed from PROPOSED, VERIFIED, GATE_FAILED, and GATE_INCONCLUSIVE. A fix already GATING returns 409 (“advance to poll it”), as does any other status.

POST /tenants/:tenantId/fixes/:fixId/submit

Delivers a VERIFIED fix (any other status returns 409).

string

required

pr — Moda’s GitHub App opens a draft PR on branch moda/fix/<shortref> with the composed body and magic word. local_ref — records that you applied the change yourself on a branch (status → APPLIED_LOCALLY).

string

The branch name. Required when channel is local_ref.

curl -X POST "https://moda.dev/api/tenants/1f7c9a2e-4b3d-4c8e-9a1b-2d3e4f5a6b7c/fixes/cme9y2k1q0001l708g6p4xw3v/submit" \

{
  "status": "PR_OPEN",
  "prUrl": "https://github.com/acme/agent/pull/128",
  "prBranch": "moda/fix/7q2wjx4m"
}

Submit enforces the throttles: at most 3 open Moda fix PRs per workspace (409), one open fix PR per problem and per target file (409 names the sibling), and older drafts for the same problem or file are superseded. The pr channel requires a routed target file and a registered candidate version (400 otherwise — content verified via upload must be handed back as a PR by the agent itself); an unconfigured GitHub integration returns 503.

POST /tenants/:tenantId/fixes/:fixId/mark-applied

The no-GitHub confirmation: you applied the candidate in your own infrastructure — updated the tool description in your agent’s tool definition, installed the drafted skill, or hand-applied a prompt edit — so there is no PR merge to confirm the fix. The fix flips straight to SHIPPED with deliveryChannel: "local", records fixRef: { appliedNote, appliedAt, promptVersionId }, and posts the same deterministic mark_fixed problem feedback the merge webhook would, with actor: "fix-mark-applied" and a fix_ref of { fix_id, short_ref, applied_note? } (no pr_url / merge_commit).

string

Optional operator note, ≤ 600 characters, recorded on fix_ref.applied_note.

curl -X POST "https://moda.dev/api/tenants/1f7c9a2e-4b3d-4c8e-9a1b-2d3e4f5a6b7c/fixes/cme9y2k1q0001l708g6p4xw3v/mark-applied" \
  -H "x-api-key: YOUR_MODA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"note": "tool description updated in our agent config"}'

Returns the updated fix plus a duplicate boolean. Allowed from any resting or delivered status (UNROUTED, PROPOSED, VERIFIED, GATE_FAILED, GATE_INCONCLUSIVE, PR_OPEN, APPLIED_LOCALLY, HANDED_OFF); pipeline-live (SCOPING, PROPOSING, GATING), pre-candidate, and terminal statuses return 409. Idempotent: marking an already-confirmed fix (SHIPPED, CONFIRMING, HELD, REGRESSED) is a duplicate no-op that still re-posts the deterministic feedback. Confirmation monitoring then behaves exactly as after a merge — CONFIRMING while the problem is in fixed-monitoring, HELD after 14 clean days from appliedAt, REGRESSED on reopen.

POST /tenants/:tenantId/fixes/:fixId/dismiss

Rejects the fix (status → REJECTED) and records the reason as problem feedback. Already-terminal fixes (REJECTED, SUPERSEDED, ABANDONED, HELD) return 409.

string

required

1–2,000 characters. Feeds the problem discovery loop.

Fix provenance on problem feedback (fix_ref)

When a PR whose body or head branch carries MODA-FIX-<SHORTREF> is merged, Moda’s GitHub App notifies the backend, which flips the fix to SHIPPED and posts a mark_fixed problem feedback with actor: "moda-github-app" and a structured fix_ref:

{
  "fix_id": "cme9y2k1q0001l708g6p4xw3v",
  "short_ref": "7Q2WJX4M",
  "pr_url": "https://github.com/acme/agent/pull/128",
  "merge_commit": "d3adb33fcafe",
  "prompt_version_id": "pver_8c33d2f1a09b44e7aa11223344556677"
}

mark-applied posts the same feedback shape with actor: "fix-mark-applied" and a fix_ref of { fix_id, short_ref, applied_note? } — no pr_url or merge_commit, because no PR exists. POST /problems/:id/feedback accepts the same optional fix_ref object on any mark_fixed you submit yourself. Notes:

fix_ref is stored on the feedback row and threaded into the problem’s lifecycle change reason for provenance; it is not part of the deterministic feedback_id, so re-asserting the same action with an amended ref converges on one row instead of minting duplicates.
If a problem that was marked fixed with a fix_ref later reopens automatically, the associated SHIPPED/CONFIRMING fixes flip to REGRESSED.
The merge notification is idempotent — redelivered webhook events converge on the same SHIPPED fix and the same pending feedback row.

Errors

Status	Meaning
`400`	Validation failure: non-UUID problem ID, unknown status filter, invalid cursor, body constraint violation, missing `localRef`, a `pr` submit without a target/candidate, or `candidateContent` on a non-`PROMPT` fix.
`401`	Missing or invalid API key / session.
`403`	Authenticated but not a member (reads) or not an admin (mutations) of the tenant.
`404`	Unknown problem or fix.
`409`	State conflict: wrong status for the action, concurrent advance, throttle hit, or duplicate PR.
`503`	A required dependency (ClickHouse, the replay service, or the GitHub worker) is unavailable or unconfigured.
