Create Cycle

Start an unattended build-review-decide cycle (protocol v0.2). Queues T1 CODE: (or SHELL:) with your build_brief on the AI Inbox and T2 REVIEW: with your review_brief, born blocked on T1. T1 (2026-09-24 throughput): kind=review_only mints T1 as CAPTURE: instead — the executor stores the bundle from the repo at HEAD without a model call and the review runs on that; dry_run=true runs the dispatch PREFLIGHT only (nothing queued) and prints every problem at once (codes title_too_long, brief_rule, brief_names_unbundled_path, artifact_over_cap, migration_as_context (tascan repo only), idempotency_replay, kind_invalid — bad kind, bad revisable_by, review_only + task_type SHELL/RESEARCH, review_only + max_questions 0), then what the API could NOT check (unchecked[]: artifact_missing_at_head always — only the executor sees the repo, and a CAPTURE naming a missing path fails with "[artifact_missing_at_head]" in its error; artifact_over_cap for any path without a byte count — pass artifact_bytes; idempotency_replay only if its lookup failed) and warnings[] (a build_brief naming a context file outside the bundle); a real create that the API refuses prints the same problems[] list (when the transport hands the tool only the first problem's text, the tool re-runs the preflight and prints the whole list). The local executor builds, stores the exact bytes of artifact_paths as a bundle (build_ref = sha256 over the manifest), the independent reviewer reviews THAT bundle, an approve verdict mints a Decision task for the human authority (one SMS), Approve mints an Integrate task for the deploy id. Revise verdicts spawn revisions (cap max_revisions, default 3); reject, human Reject, scope violations or exhausted revisions PARK the cycle (a Parked task with Resume with notes / Close). REQUIRES agent:dispatch:code. Duplicate protection: the same idempotency_key, or (keyless) the same briefs + paths on a live root, within 24 h is refused by the preflight as idempotency_replay (400, nothing queued, the existing root_id in the problem) and printed as DUPLICATE with that root_id; only a replay the preflight could not see (a race) comes back from the RPC as 200 created=false, printed the same way. Optional reviews[] attaches a multi-lens review panel (design item 14a) in place of the single OpenAI review — one review task mints per lens and every blocking lens must approve before the Decision task mints. Track with tascan_get_cycle_report (root_id). Nothing spawns a cycle on its own.

Request body

project_idstring required

Working project (UUID). Its Decisions and Agent Questions lists are created on the first cycle (coord_ensure_lists). Requires the org human authority to be configured (coord_set_authority) — otherwise 403.

titlestring required

Short human title (1-200 chars). T1 becomes "CODE: <title>" ("CAPTURE: <title>" when kind=review_only), T2 "REVIEW: <title>".

build_briefstring required

The executor prompt (1-40000 chars). Executed verbatim by the local Claude Code runner as a CODE:/SHELL: task — write it as a complete instruction, name the files, forbid nothing the runner already forbids (deploy/commit/push are refused by its context).

review_briefstring required

The reviewer prompt (1-40000 chars). The reviewer reads the stored bundle (tascan_get_build / tascan_get_build_file), the task text and the filtered trail; it returns approve, revise, reject or needs_input as strict JSON bound to the build_ref. Still required even when reviews[] is given (kept as T2's legacy description text).

artifact_pathsstring[] required

Repo-relative paths the build binds (1-64). Exactly these files are stored as the bundle and hashed into build_ref; files the executor touches OUTSIDE them fail the scope check and park the cycle. No .., not absolute, no drive letter, no backslash.

task_type'CODE' | 'SHELL' | 'RESEARCH'

T1 prefix (default CODE). CAPTURE is never caller-settable: kind=review_only makes T1 "CAPTURE:" itself. With kind=review_only the value is sent as given — CODE is accepted (T1 is still CAPTURE), SHELL / RESEARCH are refused by the API as kind_invalid.

kind'build' | 'review_only'

Cycle kind (default build). review_only = no model builds anything: T1 is "CAPTURE: <title>", a local-executor task that stores artifact_paths from the repo at HEAD as the bundle (same build_ref, size cap and scope check as a CODE build) and completes in seconds; T2 REVIEW then reviews that bundle. Use it to get an independent review of documents or of code already committed by hand. Stored as coord.kind_of_cycle on the root.

revisable_by'dispatcher' | 'executor'

review_only cycles only — who fixes a revise verdict. dispatcher (default): the cycle parks on revise as today and you re-dispatch. executor: a revise spawns a revision CAPTURE task (up to max_revisions) that is born blocked on a question task "Revise the documents, then answer to release" addressed to you — fix the files in the repo, answer that question (tascan_post_message kind=answer), and the capture re-runs on the fixed HEAD. Build cycles always revise through the executor regardless of this field.

dry_runboolean

true = PREFLIGHT only: the API validates the whole dispatch and returns every problem at once (code, path, detail) plus the unchecked[] list (what only the executor / the RPC can decide) and warnings[] — nothing is queued, no idempotency key is consumed. Recommended before every real create. Default false.

artifact_bytesobject

Optional {path: bytes} for artifact_paths — the byte length of each file in your checkout. The API cannot read the repo, so artifact_over_cap (262144-byte reviewable cap per file) is only checked for paths you give a byte count; every other path is reported under unchecked (artifact_over_cap, unchecked_at_api) — never guessed from an earlier stored bundle. Same on dry_run and the real create.

max_revisionsinteger

Revision cap (default 3): at most max_revisions + 1 builds and reviews.

max_questionsinteger

Questions a runner may ask per task before the attempt fails (default 3).

repostring

Which codebase on the executor the build runs in — an alias from the executor's allowlist (tascan-agent/repos.json), e.g. "tascan" (default), "merchskipper", "inkskipper", "rangerlizzy", "cardvault", "take1", "fitcheck", "safegrid", "eternity", "maniacs". artifact_paths are relative to that repo. An unknown alias is refused by the executor (repo_unknown) and the cycle parks.

max_cost_micro_usdinteger

Per-cycle spend cap summed over every attempt, in micro-USD (default 5000000 = USD 5). A claim that could overrun it is refused (budget_exhausted).

preview_urlstring

Optional https preview link shown on the Decision task.

checkpoint_titlestring

Optional title template for the Decision task (default "Decision: <title>").

checkpoint_descriptionstring

Optional description template for the Decision task; the build_ref, preview and findings summary are appended.

integrate_titlestring

Optional title template for the Integrate task (default "Integrate: <title>").

integrate_descriptionstring

Optional description template for the Integrate task.

idempotency_keystring

Optional caller key (≤ 200 chars). The same key within 24 h is refused as idempotency_replay (nothing queued) and printed as DUPLICATE with the existing root_id — safe to retry after a lost answer.

Response

Success. JSON body: { data: ... } or an error object { error, message }.
