description

Create a FRESH, snapshot-safe Harbor task dataset from an arbitrary input — a raw non-Harbor HF dataset (e.g. allenai/TMax-15K), a generator codebase (e.g. a GitHub repo like FrontierSmith), or just natural-language instructions with no seed data. The pipeline is a sequence of IDEMPOTENT stages — triage (pick the entry stage) → task-generation → Harbor conversion → snapshot-safe patcher → oracle-solution generation → quality gate — each with its OWN empirical test before advancing, intermediate artifacts uploaded to HF (laion/, parquet). The end artifact is a Harbor task dataset whose oracle (gold) solutions verify at a high rate, with ≤ 6 (hard ≤ 10) unique Daytona snapshots. Use when asked to "make/convert/build a task dataset", "turn <HF dataset> into Harbor tasks", "run <generator repo> into a task set", or "create tasks from these instructions". Runs LOCALLY on the Mac + Daytona (no GPU; teachers via API/vLLM). Distinct from datagen-reduce-dataset-snapshots (that fixes an EXISTING Harbor dataset's snapshot count — it IS this skill's stage 3) and datagen-launch (that generates TRACES by running agents over an existing task dataset).

datagen-create-task-dataset

Build a new Harbor task dataset — runnable agent tasks (instruction.md + environment/Dockerfile + tests/ + solution/) that is snapshot-safe (few unique Daytona environments) and oracle-verifiable (gold solution makes tests pass). Stage-based and idempotent: pick the entry stage, each independently re-runnable, each with an empirical gate before advancing; every output uploads to HF (laion/, public parquet).

Always (local-Mac conventions)

• Python = /Users/benjaminfeuer/miniconda3/envs/otagent/bin/python (full path; symlinks fail in the sandbox). source "${DC_AGENT_SECRET_ENV:?set DC_AGENT_SECRET_ENV first}" for HF + Daytona + teacher keys.
• PRE-FLIGHT (do at minute one): confirm data.commons imports cleanly — cd /Users/benjaminfeuer/Documents/OpenThoughts-Agent && <otagent python> -c "import data.commons". data.commons imports harbor.trial.trial at module level — a broken/mid-merge local harbor clone (/Users/benjaminfeuer/Documents/harbor; check ls .git/MERGE_HEAD, git -C ../harbor status) silently blocks every Daytona-dependent stage. If the import fails, STOP and surface to the user (do NOT resolve harbor merge conflicts yourself — it's core RL code).
• All pipeline CODE lives in /Users/benjaminfeuer/Documents/OpenThoughts-Agent/data/<dataset-slug>/ (a generate.py + conversion helpers). The snapshot-safety patcher lives in data/patchers/patch_<slug>_tasks.py (ls data/patchers/). Study existing examples first: data/nl2bash/, data/code_contests/, data/swegym/ and data/patchers/patch_*_tasks.py.
• Dated logs → the ABSOLUTE path /Users/benjaminfeuer/Documents/agent_logs/YYYY-MM-DD_<slug>_taskgen.md — NEVER a relative agent_logs/ (resolves to the repo cwd). Record the chosen entry stage, each gate's numbers, every intermediate HF id, and the final snapshot/oracle numbers.
• HF uploads default PUBLIC to laion/; task datasets are never DB-registered.

Sizing rule (decide at triage, write it in the log)

• Real seed data → generate the MAXIMUM-size dataset (no --limit; --limit <=0 on the patchers = no cap). Don't subsample real corpora.
• Synthetic (NL-only / teacher-generated) → pick a reasonable cap from seed material × teacher cost. State the cap + reasoning up front.

Stage 0 — TRIAGE: pick the entry stage (do this FIRST)

Stages are idempotent, so you can also resume a half-built dataset mid-pipeline.

Input	Start at
Raw non-Harbor HF dataset (records that aren't Harbor tasks — e.g. allenai/TMax-15K)	Stage 2 (Convert) — map the seed records into Harbor task dirs.
Generator codebase (a repo that emits problems/tests — e.g. FrontierCS/FrontierSmith)	Stage 1 (Generate) — clone, understand its output, run it to produce seed material, THEN Stage 2.
NL instructions, no seed data	Stage 1 (Generate) — synthesize seed tasks with a teacher (capped per the sizing rule), THEN Stage 2.
An existing Harbor dataset that's snapshot-unsafe / fails oracle	Stage 3 / 4 — this is the datagen-reduce-dataset-snapshots skill (stage 3) + the oracle gate (stage 4).

Write the chosen entry + why in the dated log. If the input is ambiguous (e.g. a repo that's both a generator AND ships a dataset), inspect before committing; ASK the user if genuinely unclear.

Compatibility pre-check (reject incompatible sources at triage, not 3 stages in): confirm the source can become a Harbor task at all:

1. Binary-verifiable reward? Harbor's verifier is pass/fail — tests/test_state.py asserts /logs/verifier/reward.txt == "1", and the oracle gate needs a gold solution that deterministically scores a pass. If the source's reward is continuous/graded (a 0–1 ratio, an optimization score that never hits 1.0) or open-ended (no deterministic gold solution — "heuristic approaches expected"), it does NOT fit the binary contract → STOP at triage and surface (building it requires redefining "pass" as a score threshold, a design change, not a pipeline run).
2. Single-container environment? Daytona builds ONE container per unique environment/Dockerfile — no docker-compose, no sidecar/judge services, no privileged, no host bind-mounts (no existing dataset uses compose). A source needing a multi-container topology can't run in the snapshot model without re-engineering the judge in-container → STOP at triage and surface it. Either failing is a go/no-go for the user, not something to grind through the stages.

Stage 1 — GENERATE seed material (generator-codebase / synthetic only)

• Generator codebase: clone to a scratch dir (NOT inside the repo), read its README + entrypoint, install its deps in a throwaway venv, run it to emit its native output (problems + tests + reference solutions). Capture raw output; do NOT yet force it into Harbor shape. Note its license + any API/teacher it calls.
• NL-only / synthetic: use a teacher (API via data/generation InferenceEngine, or a vLLM endpoint) to generate problem statements + reference solutions + tests, capped per the sizing rule.
• Gate: a handful of generated items are well-formed (problem text present, a runnable reference solution, ≥1 test that distinguishes pass/fail). Upload the raw seed to laion/<slug>-seed (parquet).

Stage 2 — CONVERT to Harbor format

Write data/<slug>/generate.py (model it on data/nl2bash/generate.py / data/code_contests/ and use data/commons.py helpers — generate_tasks_from_questions, subsample_tasks_directory/limit_tasks_directory, upload_tasks_to_hf). Each task dir must contain:

• instruction.md — the agent-facing problem (+ any runtime repo-clone/setup, so it stays OUT of the Dockerfile — see Stage 3).
• environment/Dockerfile — the build env. This file's content-hash IS the snapshot key (siblings don't affect it) — keep it SHARED across tasks (Stage 3).
• tests/ — test.sh (runs the tests), test_state.py (asserts /logs/verifier/reward.txt == "1"), config.json (pass/fail test lists).
• solution/ — solve.sh (the oracle/gold solution, typically a heredoc + git apply / direct edits). Empty/placeholder until Stage 4 if the source has no gold solution.
• task metadata (id, source, etc.).
• Harbor mounts ONLY environment/ (→ the image), solution/ (→ /solution), and tests/ (→ /tests) — there is NO /setup_files mount (named in TaskPaths but NOT wired up; verified against harbor source 2026-06-22, TMax-15K). Any per-task setup that can't live in the shared Dockerfile (Stage 3) must be carried INSIDE tests/ AND solution/ (e.g. ship a setup.sh in both and have test.sh/solve.sh source it) and inlined into instruction.md for the agent — do NOT invent a setup_files/ dir and expect it mounted. If the setup touches a cloned repo, add a git config --global --add safe.directory '*' hardening.
• Gate: extract a few tasks and confirm the schema matches a known-good dataset. Fast check = run a tiny infra smoke (Stage 5's tier-1) on ~5 tasks — does the env build + the harness run? Fix schema/Dockerfile errors here, before scaling up. Upload the converted set to laion/<slug>-tasks-raw (parquet) via upload_tasks_to_hf.

Stage 3 — SNAPSHOT-SAFE (the patcher)

Harbor's Daytona backend builds one snapshot per unique environment/Dockerfile. A per-task Dockerfile (e.g. repo@commit baked in) explodes to ~1 snapshot/task and is unlaunchable. Make a patcher (data/patchers/patch_<slug>_tasks.py) render a small shared set of Dockerfiles. Canonical template = data/swegym/generate_patched.py + the datagen-reduce-dataset-snapshots skill (read it — Stage 3 IS that skill):

• Dockerfile = FROM ubuntu:22.04 + Miniconda creating a testbed env at python={python_version}, interpolating ONLY a coarse key ({python_version}) + a per-version apt union ({extra_packages} from an apt_map). Nothing task-specific in the Dockerfile.
• Defer repo-specific git clone @commit + pip install/make into instruction.md, solution/solve.sh, tests/test.sh (run at trial time) via a get_specs(repo, version) map.
• Gate (hard): $PY -m scripts.harbor.count_snapshots_from_tasks --local-dataset <tasks_dir> → read UNIQUE ENVIRONMENTS (SNAPSHOTS): N. Target N ≤ 6, hard ≤ 10. Iterate the grouping until under. Regenerate the full dataset with --limit <=0 --target-repo laion/<slug>-tasks-patched (NEW versioned repo — never overwrite a validated artifact), then re-extract + re-count the uploaded repo end-to-end.

Stage 4 — ORACLE solutions

Every task needs a known-correct solution/solve.sh whose application makes tests/ pass.

• Source has gold solutions (most converted datasets — the patch/diff/reference): write it into solve.sh (heredoc + git apply, per swegym).
• No gold solution (NL-only / some generators): generate with a teacher, then KEEP ONLY the ones that verify (the oracle gate below is also the filter).
• Gate (THE real quality gate):

  $PY scripts/daytona/validate_and_upload_from_hf.py \
    --repo_id laion/<slug>-tasks-patched --extract_dir <cache> \
    --stages oracle --sample_size 40 --sample_seed 42 --skip_upload \
    --keep_failed_dir <dir>/oracle_failures
  # prints "Success: S  Fail: F  Missing: M" → oracle pass = S/(S+F)
  

  Target oracle pass ≥ 80% (set the floor in the log before starting). Sub-floor → inspect oracle_failures/; the Stage-3 env-collapse broke some repos' installs, OR the gold solution/test is wrong. Fix get_specs/the test harness, regenerate, re-oracle (bounded budget, 2–3 rounds — see the reduce skill's tradeoff discipline).

Stage 5 — QUALITY GATE (iterate until clean)

Tier-1 infra smoke (env builds + agent runs without crashing):

echo "laion/<slug>-tasks-patched" > /tmp/<slug>_check.md
FORCE_COLOR=1 SAMPLE_SIZE=200 ./scripts/daytona/batch_validate_from_md.sh /tmp/<slug>_check.md
# summary: /Users/benjaminfeuer/Documents/agent-traces-analysis/summary.tsv  (columns: dataset total infra_ok infra_rate solved solve_rate)

Read the THREE signals (all must hold to ship):

1. infra_rate ≈ 1.0 — envs build + harness runs. Well below 1.0 = real infra failures → inspect traces/ + failures/, fix, re-run.
2. oracle pass ≥ floor (Stage 4) — gold solutions verify. This is the correctness gate, NOT batch_validate's solve_rate.
3. solve_rate reasonable for the difficulty — the weak agent's (Qwen3-8B) task-solve rate. LOW for hard tasks (expected) but NOT ~0 across easy tasks (≈0 everywhere can signal mis-specified tasks/grading) and NOT ~1.0 on tasks meant to be hard (trivial/leaked answer). Judge against the dataset's intended difficulty.

Iterate Stages 3–5 until: snapshots ≤ 6, oracle ≥ floor, infra ≈ 1.0, solve_rate sane. Then the dataset is shippable.

Finish

• The shippable artifact is laion/<slug>-tasks-patched(-vN). Record in the dated log: every intermediate HF id, the final snapshot count, oracle pass %, infra_rate, solve_rate, and the entry stage taken.
• Add the dataset to the relevant tracker if one applies (e.g. notes/ot-agent/task_repos/). Clean up scratch/extract dirs.

Guardrails

• Empirical gate every stage — do not advance on a green count alone. Snapshots-green + oracle-red is a FAILED dataset (broken reward signal).
• Never raise/bypass the Daytona snapshot cap — reduce the real count (snapshot-reduce skill). Never overwrite a validated artifact — new versioned repo each regenerate.
• If a stage is genuinely blocked (license forbids redistribution, generator needs a key we don't have, oracle floor unreachable at any <cap grouping) → STOP and surface the specifics; don't loop.
