If invoked from a session that already touched the project, the skill must use its tainted-session catch: keep the parent session as orchestrator, spawn fresh role-specific subagents with only the verbatim invocation and confirmed paths, or cancel. That separation is what makes it independent. The Claude that built the pipeline cannot objectively audit it. Asking it to do so is like asking a student to grade their own exam. + +**Invoke it with:** `/referee2 code path/to/project` + +For code audits, the parent session may override default subagent model choices: + +```text +/referee2 code path/to/project --Agent0=opus --AgentA=opus --AgentA-script=sonnet --BC=sonnet --parallel +``` + +By default, Agent 0 and a single lead Agent A use a frontier reasoning model; bounded per-script Agent A extraction workers and B/C replicators use a strong mid-tier model. Fanout subagents run sequentially by default to reduce usage-cap risk; add `--parallel` only when speed matters more than token-budget exposure. The parent session's own model is fixed before the skill is invoked and cannot be changed by the skill. + +--- + +## The Five Audits + +### Audit 1: Code Audit +Scrutinizes implementation for coding errors, missing value handling, merge diagnostics, and variable construction problems. Points to exact files and line numbers. Explains why each problem matters. + +### Audit 2: Cross-Language Replication +Creates independent replication scripts in two additional languages (R → Stata + Python, or Stata → R + Python, etc.) and compares results to 6+ decimal places. The key insight: if Claude wrote R code with a subtle bug, asking the same Claude to write Stata will likely produce a *different* bug — cross-language comparison exploits that orthogonality to surface errors that single-language audit misses. + +Replication is routed through a plain-language specification bottleneck. Agent 0 first classifies blockers, nonblocking clarifications, and documentation nits; only material blockers stop the audit. Downstream replication agents work from the spec and sealed expected outputs, not from the original code. + +For large multi-script projects, the parent orchestrator may fan out bounded per-script Agent A extraction workers before a lead Agent A synthesizes the final spec. This is an orchestration choice made by the parent; subagents should not be expected to spawn their own subagents. If Agent A is fanned out, B/C should be fanned out on the same script or script-group units, sequentially unless the user supplied `--parallel`. + +### Audit 3: Directory & Replication Package Audit +Checks folder structure, relative paths, naming conventions, master script, README, and dependencies. Scores replication readiness on a 1–10 scale. The standard: can a stranger reproduce this from scratch? + +### Audit 4: Output Automation Audit +Verifies that tables and figures are programmatically generated — not manually typed or manually exported. Hardcoded in-text statistics are a major concern. + +### Audit 5: Econometrics Audit +Verifies that the identification strategy is credible, specifications are correctly implemented, standard errors are clustered appropriately, parallel trends are tested (if DiD), and effect sizes are plausible. + +--- + +## Critical Rule: Referee 2 Never Modifies Author Code + +Referee 2 can read, run, and create its own audit artifacts.

Subagents cannot be assumed to spawn other subagents. The parent stays in charge of orchestration and spawns each role-specific fresh subagent itself: + +1.

Parent spawns Agent 0 and waits for the gate result. +4. If Agent 0 blocks, parent reports blockers to the user and stops. +5. If Agent 0 does not block, parent spawns Agent A and waits for `ready_for_BC=yes`. For large multi-script projects, the parent may instead fan out bounded per-script Agent A extraction workers, then spawn or retain a lead Agent A to synthesize their artifacts into the final spec and expected-output extracts. This fanout is parent-owned; per-script workers must not spawn subagents. The parent passes extraction artifact paths to the lead Agent A, not parent-written summaries of those artifacts. +6. Parent writes the restricted B/C manifest. +7. Parent spawns Agents B and C and waits for their triage results. By default, fanout subagents run sequentially to reduce usage-cap risk; if the user supplied `--parallel`, the parent may run same-stage fanout subagents in parallel. If the parent used Agent A fanout, B/C should be fanned out on the same script or script-group units: each Agent A extraction unit gets one B replicator and one C replicator in the assigned replication languages. +8.

It can choose model tiers only when spawning role subagents, subject to the host tool's available model names. + +Default subagent model tiers: + +| Role | Default model tier | Rationale | +|---|---|---| +| Agent 0 | frontier reasoning model, e.g. Opus or GPT-5.5 | Materiality judgments, econometric stakes, comment/code divergence, and scope ambiguity are high-risk. | +| Agent A, single lead translator | frontier reasoning model, e.g. Opus or GPT-5.5 | Full-pipeline compression into a prose/math spec is high-risk when one agent handles the whole scope. | +| Per-script Agent A extraction workers | strong mid-tier model, e.g. Sonnet or GPT-5.4 | Bounded script transcription is mostly extraction; the lead Agent A owns synthesis. | +| Agents B/C | strong mid-tier model, e.g. Sonnet, GPT-5.4, or GPT-5.3-Codex | Replication work needs coding reliability more than frontier judgment. | + +Respect explicit user model choices. The user may add optional flags to the `/referee2` invocation: + +```text +--Agent0= +--AgentA= +--AgentA-script= +--BC= +--parallel +``` + +`--BC=` applies to both B and C. B and C exist only to run different replication languages, so they use the same model selection. Exact model names are host-dependent; accept common aliases when unambiguous, such as `opus`, `sonnet`, `gpt5.5`, `gpt-5.5`, `gpt5.4`, `gpt-5.4`, `gpt5.3-codex`, `gpt-5.3-codex`, `gpt5.4-mini`, and `gpt-5.4-mini`. + +By default, parent-owned fanout runs sequentially: complete one per-script Agent A worker before starting the next, and complete each B/C replication unit before starting the next unit. This avoids spending large amounts of tokens on multiple one-shot subagents that may all fail if the user hits a usage cap mid-stage. If the user supplies `--parallel`, the parent may run same-stage fanout workers concurrently when the host supports it. `--parallel` does not change the isolation rule: each subagent still gets only its assigned role context and must not spawn further subagents. + +If the requested model is unavailable, tell the user which role cannot use it and fall back to the nearest available model in the same tier.

Where results differ, **classify and diagnose** per the triage table below + +### The Specification Bottleneck + +**Why this exists.** If the auditor reads the original code (comments and all) and translates line-by-line into another language, the orthogonality argument collapses — the new code reproduces the same conceptual mistakes in different syntax, and the bug survives translation. The spec bottleneck forces compression through a verbal layer where ambiguities surface and where independent implementation can re-derive the structure. + +**Why telling one agent to "set the original code aside" doesn't work.** Context cannot be unread. A single Claude that sees the original code and then writes the spec and then writes the replication is implementing from-the-code, not from-the-spec — the spec becomes a side channel while the original code drives the translation. To enforce the bottleneck, the agent that reads the original code and the agents that write the replications must be **separate subagents with isolated contexts**. + +**If a handoff cannot happen, stop at the missing stage.** Agent A writing B/C's R, Python, or Stata scripts invalidates the cross-language replication. Agent 0 writing Agent A's spec is also invalid. If the parent cannot spawn the next required isolated role subagent, do not continue in the same context. Preserve completed artifacts, report `Status: partial-audit-replication-blocked`, and allow a later invocation to resume at the next missing role if source state is unchanged. + +**Four-agent architecture:** + +| Agent | Reads | Produces | +|---|---|---| +| **0 — Auditor** | Full scope manifest, active override ledger, original code + comments, source outputs for provenance | Materiality-tiered readiness findings only. Does NOT write a spec. | +| **A — Translator** | Original code + comments, full scope manifest, active override ledger, source-of-truth outputs | Spec file + expected-output extraction files and notes. | +| **B — Replicator (language 1)** | Restricted manifest, spec, input data, path-assignment config only. Expected outputs and source outputs are sealed until first-run artifacts are saved. **Never sees the original code.** | First-run replication script/output, optional revised script/output, comparison table. | +| **C — Replicator (language 2)** | Same as B; never sees original code. | First-run replication script/output, optional revised script/output, comparison table. | + +The parent session orchestrates by spawning role subagents and aggregating their reports. **The parent does not perform the role work.** It may create manifests, pass artifact paths, wait for subagent results, present blocking menus, and write the final report from role-subagent outputs. It must not read original code to audit it, write Agent A's spec, or write B/C replication scripts. **The parent does not read spec content** — it only passes file paths to B and C. The parent's own context is contaminated (it has the user's invocation and Step -1's enumeration); if it summarizes the spec into B/C's prompts, that contaminated paraphrase replaces the clean spec. Hand off via `Read these files before doing anything: , , ` and let B/C read the files themselves. If a role subagent cannot be spawned, the parent must not ask the previous role or itself to "just do the next step." + +**Why split Agent 0 from Agent A.** A single agent that does "audit, and if clean write the spec" judges its own gate. Splitting prevents Agent 0's comment/code read from becoming the spec-writing voice. Agent 0 gates only material blockers; nonblocking clarifications and documentation nits proceed as flagged audit state. + +**The protocol:** + +1. **Discover and confirm the scope bundle.** Default to the audited entrypoint(s), sourced/imported code, configs, required inputs, and source-of-truth output artifacts. If the user explicitly narrows scope, honor that guardrail and record it. +2. **Check for resumable artifacts.** Before creating a new round, check whether the newest incomplete round for the same scope can resume: + - Agent 0 findings exist with no blocking issues, but no matching Agent A spec exists: ask whether to resume at Agent A. + - Agent A spec, expected-output artifacts, expected-output notes, and restricted manifest exist, but matching B/C comparison artifacts are missing: ask whether to resume at B/C. + Resume only if the source files and source-output artifacts listed in that round's full scope manifest are unchanged since the last completed stage artifact was written. If anything changed, start a new round from Agent 0. +3. **Write the full scope manifest for a new round.** If not resuming, create `correspondence/referee2/YYYY-MM-DD_roundN_scope.md`. Infer `roundN` by scanning existing `correspondence/referee2/YYYY-MM-DD_round*_*.md` files for today's date and taking max `N + 1`; if none exist, use `round1`. Include enough source-state information to support later resume checks: at minimum path, file size, and modified time for original code/config/source-output artifacts, and hashes where feasible. +4. **Read active overrides.** If `correspondence/referee2/referee2_overrides.md` exists, read only entries with `Status: active`. If it does not exist, create it lazily only when the first override is needed. +5. **Spawn Agent 0 (auditor).** Prompt: audit full spec-readiness across comment/code divergences, scope-bundle ambiguities, and run-state/output provenance ambiguities. Return materiality-tiered findings. Do NOT write a spec. +6. **Gate only on material blockers.** If Agent 0 finds `blocking` issues not covered by active overrides, stop for user review and follow the blocking menu below. If Agent 0 finds only `nonblocking-clarification` or `documentation-nit` issues, proceed automatically and carry relevant `REFEREE2_FLAG[...]` assumptions into Agent A. +7. **Spawn Agent A (translator).** Prompt: read the source code and source-of-truth outputs, treat executable code behavior as authoritative, and write the spec to `code/replication/YYYY-MM-DD_roundN_spec_.md`, expected-output extraction files, and `YYYY-MM-DD_roundN_expected_outputs__notes.md`. Agent A stops after writing these artifacts and returns a one-line status: `spec= outputs= notes= restricted_manifest_needed=yes ready_for_BC=yes`. For large multi-script projects, the parent may first spawn bounded per-script Agent A extraction workers and then give their artifact paths to the lead Agent A. The parent, not any subagent, decides whether to use this fanout. +8. **Write the restricted B/C manifest.** Create `correspondence/referee2/YYYY-MM-DD_roundN_restricted_manifest.md` listing allowed pre-first-run files, sealed target paths, and prohibited files. +9. **Verify B/C handoff availability.** Before beginning cross-language replication, confirm that B and C can run as separate isolated subagents. If they cannot, stop with `Status: partial-audit-replication-blocked`; keep the Agent A artifacts for a later resume at B/C. +10. **Spawn Agents B and C.** Each receives the restricted manifest, spec path, and input data paths. Each writes and runs a first-run replication before opening expected outputs or source outputs. Each compares after first-run artifacts are saved, may make diagnostic revisions, and returns a triage table. If Agent A was fanned out by script or script group, fan out B/C on the same units so every extraction unit gets one B-language replication and one C-language replication. Run fanout units sequentially by default; run same-stage units in parallel only when the user supplied `--parallel`. +11. **Run output automation check only if user requested it.** If and only if the user explicitly asked referee2 to check output automation/rerun reproducibility, the parent may run the original entrypoint and compare generated source artifacts to the pre-existing source-of-truth outputs. This is parent-owned diagnostic evidence and is separate from Agent A's expected-output extraction. +12. **Aggregate.** The parent collects B's and C's triage tables, combines them with the other audits, and files the formal report. The triage table format and discrepancy categories are defined further down. + +### Agent 0 Materiality Tiers + +Agent 0 does not use a binary clean/dirty gate. It classifies each finding into one of three tiers: + +| Tier | Meaning | Gate effect | +|---|---|---| +| `blocking` | A reasonable replication could produce different scientific conclusions depending on whether code, comments, scope, or output provenance are treated as authoritative. | Stops Agent A unless covered by an active override. | +| `nonblocking-clarification` | A mismatch or ambiguity exists, but Agent 0 can state why it is unlikely to affect the model, sample, variables, or reported outputs. | Proceeds to Agent A with a `REFEREE2_FLAG[...]` assumption where relevant. | +| `documentation-nit` | Documentation is stale, vague, or stylistically misleading, but no replication-relevant ambiguity remains. | Proceeds; report in Agent 0/final report only. | + +Usually classify as `blocking` when the issue affects model equations, estimators, identifying variation, sample inclusion/exclusion, treatment/control definitions, outcome construction, key covariates, fixed effects, clustering, weights, standard errors, units/scaling, merge keys, or timing/order where results could change. + +Usually classify as `nonblocking-clarification` when the issue affects precision finer than the data contain, harmless label looseness, implementation details with no plausible impact on estimates, documented/inferable default behavior, or edge-case handling for cases absent from the observed data. + +Anti-overconfidence rule: when unsure whether a mismatch is blocking or nonblocking, classify it as blocking unless Agent 0 can state why the distinction is unlikely to affect the model, sample, variables, or reported outputs. + +Agent 0 finding IDs use one grep-friendly token: + +```markdown +REFEREE2_FLAG[A0-YYYY-MM-DD-###] +Tier: blocking | nonblocking-clarification | documentation-nit +Scope: +Issue fingerprint: +Evidence: +Materiality rationale: +Downstream assumption: +Blocks Agent A: yes | no +``` + +Agent 0 should include a separate `Possibly retired active overrides` section when an active ledger entry appears obsolete. It must not retire overrides automatically. + +### Blocking Menu and Override Ledger + +If Agent 0 finds uncovered blockers, parent presents this bounded menu and stops the audit until the user chooses: + +```markdown +Agent 0 found blocking divergences. Referee2 cannot proceed to Agent A until each blocker is resolved or explicitly overridden. + +For each blocker, choose one: +1. I will fix the code/comment outside referee2, then rerun. +2. Mark as intentional and add an active override. +3. Proceed with unresolved risk and add an active override. +4. Cancel the audit for now. +``` + +Option 1 stops referee2. Do not edit source inside the audit. The user fixes code/comments outside referee2 and reruns. + +Options 2 and 3 append entries to `correspondence/referee2/referee2_overrides.md`. Override IDs use `REFEREE2_FLAG[OVR-YYYY-MM-DD-###]`; choose the next unused number for the date. Overrides are always user-decided and agent-entered: the parent may draft and append the ledger entry, but only after the user explicitly chooses an override for a specific Agent 0 blocker. + +Ledger template: + +```markdown +# Referee2 Override Ledger + +If source code/comments are later changed so an override no longer applies, mark the entry `Status: retired` and explain the retirement reason.

Agent A reads active overrides only to encode localized `REFEREE2_FLAG[...]` assumptions in the spec. Agents B and C never read the override ledger. + +### Required Subagent Prompt Components + +Use these components when the parent spawns the code-audit role subagents.

If yes → the spec is doing its job. If both would write identical-shaped code → the spec has collapsed back into the original. + +### Comment handling — comments are claims to verify, not guides to trust + +Well-documented code is a net asset for auditing — comments are the self-report against which the auditor verifies behavior. But comments create a specific bias risk in two places: + +1. **Comment-anchored reading** can hide off-by-ones, sign errors, and unit mismatches. A comment saying "loop over i = 1..n" before code that says `for i in range(n)` (which is 0..n-1) gets skimmed past. +2. **Comments-and-code-together translation** in cross-language replication imports the conceptual model into the target language, defeating orthogonality (this is what the spec bottleneck above protects against). + +**Rule for the Code Audit:** read the code first, treating comments as `` (visible but parsed last). Verify behavior independently. Then check whether the comments accurately describe what the code does. **Any comment/code divergence is a finding, not an annotation to silently reconcile.** Classify each finding using the Agent 0 materiality tiers. Examples that must be flagged: + +- Comment says "robust SE clustered at firm" but code uses HC1 +- Comment says "drop observations with missing wages" but code drops missing in any regressor +- Comment says "log transform" but code uses log1p (or vice versa) +- Comment specifies one functional form, code implements another + +This audit is operationalized as Agent 0 in the four-agent architecture above. Agent 0 returns findings to the parent. Only material `blocking` findings stop Agent A. Nonblocking clarifications proceed as localized `REFEREE2_FLAG[...]` assumptions; documentation nits are reported but do not enter the spec unless they affect interpretation. + +Agent A always writes the spec from executable code behavior. If the user says comments are correct and code is wrong, stop the audit so author code can be fixed outside referee2. + +### Expected Outputs and Sealed Targets + +Existing output artifacts are the source of truth by default. Expected-output files should usually be structured extractions from the project's existing tables, figures, or result files, not newly generated outputs. Agent A must not rerun original code to refresh, regenerate, or validate source outputs before extraction. Rerunning original code is allowed only when the user explicitly requested an Output Automation Audit rerun/reproducibility check, and that check is parent-owned diagnostic evidence rather than Agent A work. + +Agent A writes: + +- `code/replication/YYYY-MM-DD_roundN_expected_outputs_.csv` for table-like numeric targets by default +- `code/replication/YYYY-MM-DD_roundN_expected_outputs_.json` when outputs are nested, scalar dictionaries, or multi-panel objects where CSV would obscure structure +- `code/replication/YYYY-MM-DD_roundN_expected_outputs__notes.md` always + +For table-like outputs, use these columns where applicable: + +```csv +output_id,model,term,statistic,value,unit,source_artifact,source_location,notes +``` + +The notes file documents: + +- source artifact(s) +- provenance: existing artifact treated as source of truth; rerun not requested / user-requested rerun attempted and matched / user-requested rerun attempted and differed +- extraction choices +- stale-output concerns, if any +- sealed-output instructions for B/C + +Stale-output checks are separate from expected-output extraction. Agent A should not block B/C merely because output artifacts may be stale and should not regenerate outputs to resolve staleness. Block B/C only if no meaningful source-of-truth expected values can be extracted or defined for the target output. If artifacts appear stale, record the concern in the expected-output notes and final report. + +### Optional Output Automation Rerun + +Run the author's original entrypoint for bytewise or numeric output-regeneration checks only when the user explicitly asks for that check in the referee2 invocation or follow-up. Do not infer this from ordinary code-audit mode. + +When requested, the parent owns the rerun check after Agent A has extracted expected outputs from existing artifacts. The parent may run the original entrypoint and compare pre-existing source artifacts against regenerated artifacts or post-run hashes. Record the result in the final report and expected-output notes as parent-owned Output Automation Audit evidence. A rerun mismatch is an audit finding; it does not authorize Agent A, B, C, or the parent to edit author code. + +Parent writes a physical restricted manifest for B/C at `correspondence/referee2/YYYY-MM-DD_roundN_restricted_manifest.md`. It contains: + +```markdown +## You may read before first run +- code/replication/YYYY-MM-DD_roundN_spec_.md +- code/config.do only for path assignment; do not inspect analysis logic +- data/derived/panel_daily.dta only to confirm schema/units and run replication + +## Sealed until first-run outputs are saved +- code/replication/YYYY-MM-DD_roundN_expected_outputs_.csv +- code/replication/YYYY-MM-DD_roundN_expected_outputs__notes.md +- output/tables/main_results.tex + +## You must not read +- original entrypoint scripts +- sourced analysis/helper scripts +- existing output artifacts before first-run outputs are saved +- expected-output files before first-run outputs are saved +- prior referee2 reports +- override ledger +- full scope manifest +``` + +B/C may receive sealed target paths up front, but must not open them until after writing the replication script, running it to completion, and saving first-run outputs. Each B/C report must state: + +```markdown +Expected outputs opened after first-run outputs saved: yes/no +First-run output path: +``` + +B/C must also write a round-specific first-run lock file after first-run outputs are created and before opening expected outputs or source outputs: + +```markdown +correspondence/referee2/YYYY-MM-DD_roundN__first_run_lock.md +``` + +Lock file contents: + +```markdown +# Referee2 First-Run Lock + +Language: +Round: YYYY-MM-DD_roundN +Spec path: +First-run script path: +First-run output path: +Timestamp first-run output saved: +Expected outputs opened before first-run: no +Source outputs opened before first-run: no +``` + +B/C may revise after opening expected outputs, but must preserve first-run scripts and outputs.

Preserve the failed script and a failure log, then make diagnostic changes only to referee-owned replication artifacts or environment-access helpers while expected/source outputs remain sealed. The first successful run that creates outputs becomes the first-run artifact and receives the lock. Revision logs classify each change as `spec misread`, `package default mismatch`, `spec gap`, `original-code discrepancy`, or `numerical/formatting issue`. + +Formatting differences are immaterial unless they change substantive results. Do not revise solely to match table layout, labels, stars, decimal display, column order, LaTeX formatting, or file naming. + +For figures, Agent A should identify numeric targets where possible: plotted points, event-study estimates and confidence intervals, coefficient plot values, bin means, histogram/bin counts, or sample sizes behind plotted groups. If a numeric backing file exists, use it as expected output. If no stable numeric target exists, create a flag: + +```markdown +REFEREE2_FLAG[FIG-YYYY-MM-DD-001] +Tier: figure-human-comparison +Scope: output/figures/
.pdf +Issue fingerprint: figure output is not reducible to stable numeric targets; human visual comparison required. +Downstream assumption: B/C should reproduce the figure from the plain-language spec and save rendered outputs; referee2 will not classify visual match automatically. +``` + +First-run figures use `code/replication/referee2__first_run_.`. Revised figures use `code/replication/referee2__revised_.`. Numeric backing outputs use the same stem with `_data.csv` or `_data.json`. B/C may make qualitative comparisons only after first-run artifacts are saved, and must label those comparisons qualitative unless numeric targets exist. + +### Discrepancy triage — classify at finding-time + +When the cross-language replication produces different numbers, classify each discrepancy IMMEDIATELY into one of three categories before drilling further. The category determines what to do next. + +| Category | What it means | What to do | +|---|---|---| +| **Substantive** | Different model, estimator, identifying variation, or target parameter | Real finding. Deep dive. Likely a bug in original or replication. | +| **Ancillary, specified in spec** | The replicator implemented section 2/3/4 contrary to the spec | Auditor error. Fix the replication and rerun. | +| **Ancillary, absent from spec** | Replication used a different default for something the spec didn't pin down | **Sensitivity finding, not a bug.** Report as: "result depends on choice X; you may want to make that intentional." | + +The third category is the key reframe. It is NOT "wasted time hunting a phantom bug." It is a finding: *the headline number is sensitive to a choice the author didn't realize they were making.* Published replication failures often trace back to undocumented nuisance choices, not to bugs in either implementation. + +**Output format reflects the triage** — discrepancies are tagged with category and treated differently: + +``` +Cross-language comparison (Stata original vs. R replication): + +Coefficient on schooling: + Stata: 0.087 (SE 0.012) + R: 0.091 (SE 0.013) + Diff: +0.004 (4.6%) + Category: Ancillary, absent from spec + Reason: Stata default = listwise deletion; R replication = complete-case on + regressors only.

Do not spawn one "referee2 subagent" and expect it to run the whole protocol; role subagents may not be able to spawn other subagents. The parent must spawn each fresh role subagent directly and wait for that role's return before deciding the next step. + +For large multi-script code audits, the parent may choose a fanout Agent A pattern: spawn one bounded extraction worker per script or coherent script group, then have a lead Agent A synthesize the final seven-section spec and expected-output artifacts from those extraction artifacts. Use this only when it reduces context bloat or cost without weakening the spec bottleneck. Per-script workers write extraction notes only; they do not write the final spec, run replications, compare outputs, or spawn further subagents. The parent passes extraction artifact paths to lead Agent A rather than summarizing the workers' findings. If Agent A is fanned out, B/C should be fanned out on the same script or script-group units. Run fanout units sequentially by default; use parallel fanout only when the user supplied `--parallel`. + +The Agent 0 gate is materiality-based: + +- No blockers: parent spawns Agent A next. +- Active overrides: parent proceeds to Agent A, and Agent A carries override flags into the spec. +- Nonblocking flags: parent proceeds to Agent A, and Agent A carries relevant flags into the spec. +- Blocking findings not covered by active overrides: parent stops with `Status: blocked-on-user-review` and reports Agent 0's findings plus the blocking menu. +- Agent A handoff unavailable after Agent 0: parent stops with `Status: partial-audit-replication-blocked` after preserving Agent 0 findings. A later invocation may resume at Agent A if source state is unchanged. +- B/C handoff unavailable after Agent A: parent stops with `Status: partial-audit-replication-blocked` after preserving Agent A artifacts. A later invocation may resume at B/C if source state is unchanged. + +If the parent stops on blockers, the user can fix code/comments outside referee2, add overrides, cancel, or rerun after changes. A later fresh Agent 0 subagent re-runs against the current source; it never relies on prior audit narrative. + +If the parent stops because a role handoff is unavailable, return only the resumable artifact paths for completed stages. On a later invocation, the parent may offer to resume from the next missing role if those artifacts are the newest matching round for the same scope and the source files/source-output artifacts listed in the full scope manifest have not changed. If source state changed, start over at Agent 0. + +### Liberal gap-flagging in Agent A + +Even after Agent 0's audit is clean, Agent A may find the original code is silent on something in spec section 5 (missingness, edge cases) or sections 2/4 (sample, variable construction). Agent A cannot pause to ask the user — it is also single-shot. Do NOT skip the section and do NOT refuse to proceed. Do both: + +1. **Record the gap explicitly** in the spec: + ``` + ## 5. Missingness and edge-case handling + ORIGINAL CODE SILENT on missingness — no explicit drop_na, no `if !missing()`, no `dropna()`. + ``` +2. **Pick a defensible default and document the choice:** + ``` + Replication assumption: listwise deletion across all model variables + (matches Stata's `regress` default; this is the most common econometric + convention). If author intended otherwise, this becomes an "Open question + for the user" in the final report. + ``` + +Agent A proceeds with documented assumptions. Refusing to proceed because of gaps would make the audit unactionable. + +**The triage table is the report format, not mid-run dialogue.** Classify each discrepancy yourself, include reasoning, present the three categories distinctly in the final report. + +**Final report structure (subagent return value after a completed B/C handoff):** + +```markdown +## Spec +[Path to the seven-section spec; do not paste the full spec unless the user asked for inline detail] + +## Substantive discrepancies (likely real findings) +[List with deep-dive diagnosis] + +## Ancillary spec violations (replication errors) +[List — fix-and-rerun within this run if time permits, else flag] + +## Sensitivity findings (results depend on assumptions absent from original code) +[List with: which spec section, what default I assumed, what alternative would do] + +## Open questions for the user (cannot be resolved without input) +[List of spec gaps where my default may be wrong; user can resolve in a follow-up invocation] + +## Other audit findings +[Code audit, directory audit, output automation audit, econometrics audit findings] +``` + +**Resolution loop.** After the parent aggregates role-subagent results, the parent surfaces the report to the user. If the user wants to resolve open questions, they update the code and/or provide spec answers, then re-invoke referee2 in the same parent session. New fresh role subagents run against the updated state. Per Step -1's "Iterative re-invocation" rule: new role-subagent prompts must NOT include the prior audit's findings — only the current code, current spec, and scope. + +**Resume loop.** If a prior round stopped with `partial-audit-replication-blocked`, a later invocation may resume from the next missing role rather than rerun completed stages. If Agent 0 completed but Agent A did not, resume at Agent A. If Agent A completed but B/C did not, resume at B/C. The parent must ask the user before resuming and must verify unchanged source state using file paths and timestamps or hashes from the prior scope/spec artifacts. Resume prompts receive only the artifacts needed for the next role; they do not receive prior report narrative or the reason the handoff failed. + +--- + +## Filing the Report + +### Report Format +Use the formal referee report template from `~/.claude/skills/referee2/referee2.md`: +- Summary +- Status: `passed`, `blocked-on-user-review`, `partial-audit-replication-blocked`, `proceeding-with-nonblocking-flags`, `human-figure-comparison-required`, or `failed-substantive-discrepancy` +- Status is the audit workflow state, not the substantive referee verdict. +- Findings by audit +- Major Concerns (must be addressed) +- Minor Concerns (should be addressed) +- Questions for Authors +- Verdict +- Verdict is the substantive referee judgment: Accept, Minor Revisions, Major Revisions, or Reject.
