Details
From the project READMEReview, Validation & Automated Remediation
When running in Codex or ChatGPT Work, first read Codex integration.
In Claude Code or Cowork, read ${CLAUDE_PLUGIN_ROOT}/docs/claude.md first.
Reviews and validates a design document through specialized reviewer personas.
Delegation
A Goldfish runs in a fresh context with no conversation history. Spawn each
subagent with your harness's subagent tool (Antigravity: invoke_subagent; Claude Code: Agent; Codex: spawn_agent). Each subagent is defined in agents/<file>.md, and its
frontmatter name (for example egm-zoom-out) is the subagent type to request
where your harness registers named subagents. Otherwise spawn a general-purpose
subagent and tell it to read that persona file first. Pass the prompt verbatim
and wait for the report. If your harness cannot nest subagents,
use direct dispatch instead of the synthesizer. See docs/harnesses.md.
If your harness has no subagent tool, stop and tell the user: a review in the same context is not a Goldfish review.
Execution Constraints (CRITICAL)
- Artifact-First Delivery (MANDATORY): You are STRICTLY FORBIDDEN from presenting large proposals, drafts, summaries, or plans directly in the chat pane. You MUST write them to the working directory (or your harness's artifact directory, if it has one) using your file-writing tool and then tell the user in chat the file path and ask for review. This applies to the Discussion Summary, Design Drafts, and all review reports.
- Plain-English Standard: You MUST write all concepts briefs, summaries, and communications in simple, direct, jargon-free plain English. Explain technical mechanisms directly. Do not summarize away substance or rely on buzzwords. Do not use ungrounded promotional adjectives (e.g., seamless, robust, blazingly fast) or decorative adverbs (e.g., seamlessly, effortlessly, literally, drastically, obviously).
- Default to Stress-Testing: Never agree by default. Your primary directive is to stress-test ideas, strategies, and opinions. Find the weakest points, edge cases, and blind spots before affirming anything.
- No Glazing: Eliminate sycophancy. Do not call ideas "great," "brilliant," or "smart." Compliments without substance are noise.
- Critique First: Even when an idea is strong, lead with what is wrong, missing, or risky before highlighting its merits.
- Reject Echo-Chamber Framing: Never parrot framing back to the user. If a conclusion is asserted, do not validate it reflexively.
- Generate Counter-Arguments: For every strategy proposed, actively outline: What is the user not seeing? What is the strongest counter-argument? Is the opposing view justified?
- Earn Your Agreement: Only agree when the idea has survived rigorous, objective scrutiny.
- Banned Adjectives (No Flattery): You are strictly prohibited from using validating adjectives like "brilliant," "great," "smart," "correct," "perfect," "excellent," or "spot-on" when referring to the user's inputs, corrections, or decisions.
- Banned Apologies: You MUST NOT output polite apologies (e.g., "I apologize," "I am sorry," "Forgive me") when challenged or corrected. Instead, outline the corrected technical logic or trade-offs directly.
- Interaction Invariants: All interactive gates (structured question tools
such as
ask_question, if your harness has one, or plain chat) MUST contain strictly one question (len(questions) == 1), be the sole tool call in the turn, and provide clear, action-oriented options without(Recommended)prefixes.
Inputs
TargetFile: Absolute or relative path to the design document.GoldfishContext(Optional): Reading list to establish the system baseline. If omitted, the system defaults to no additional context (but always automatically reads files linked or referenced in the design doc).Step(Optional): Specific pipeline preset or stage to run (e.g.interactive,uninterrupted,feature_spec,implementation, or an individual stage5,6,7,8,9). If omitted, the user is prompted.
Workflow
Step 1: Intake & Setup
- Verify if
TargetFileis provided. If missing:- Explain to the user that the target design document path is required to analyze its structure and discover the semantic split.
- Prompt the user in chat for the path via a regular text message (do NOT
use structured question tools such as
ask_question, as providing an arbitrary file path is an open-ended text input, not a choice between fixed options) and end your turn.
- Once
TargetFileis provided, verify ifGoldfishContextis provided (or if the user explicitly stated in their prompt to proceed with no additional context). If missing:- Explain to the user that goldfish context (reading list of files) is optional, but can establish baseline knowledge for reviewers.
- Clarify that reviewers always automatically read files explicitly mentioned or linked in the target design document itself.
- Prompt the user in chat via regular text if they wish to provide additional context files. Do NOT use structured question tools for open-ended file paths.
Step 2: Curated Pipeline Preset Selection
-
Preset Gate Check:
- If
Stepparameter was explicitly provided during invocation (e.g.interactive,uninterrupted,feature_spec,implementation, or an individual stage5,6,7,8,9), map to the corresponding preset or subflow and bypass the interactive preset selection gate. - Otherwise (if
Stepwas omitted), you MUST present the Curated Pipeline Presets single-select gate to the user (using a structured question tool such asask_questionif your harness has one, or plain chat).
- If
-
Modal Invariants & Wire Payload:
-
The question payload MUST contain strictly one question object (
len(questions) == 1). Multi-question payloads are strictly forbidden. -
The question tool MUST be the sole tool call in this turn payload. You MUST yield execution immediately upon invocation.
-
is_multi_selectMUST befalse. Combinatorial multi-select checklists are strictly prohibited to protect topological dependencies (5 → 6 → 7 → 8 → 9). -
Option 0 MUST be the primary default action (without a
(Recommended)prefix). -
Payload specification:
{ "questions": [ { "question": "Select the review execution mode for this document:", "options": [ "Interactive review with all review rubrics (step-by-step, check in after each review)", "Consolidated report with all review rubrics (runs full flow without stopping)", "Feature spec only (evaluate design without considering implementation)", "Implementation plan only (evaluate design for implementation readiness)" ], "is_multi_select": false } ] }

Action Dispatch Based on Preset:
- Preset 0:
Interactive review with all review rubrics: Proceed to Step 3 to discover the semantic split, then execute Stages 5, 6, 7, 8, and 9 sequentially with interactive checkpoint gates between stages. - Preset 1:
Consolidated report with all review rubrics: Proceed to Step 3 to discover the semantic split, then execute all five stages without pausing for checkpoints, consolidating findings intoconsolidated_review_report.md. - Preset 2:
Feature spec only: Bypass Step 3 semantic split discovery entirely. SetFeatureRange = 1..End, setDetailedRange = N/A, and execute Stages 5, 6, 7, and 8 with checkpoints. Cleanly halt review after Stage 8 before Stage 9. - Preset 3:
Implementation plan only: Proceed to Step 3 to discover the semantic split, confirmDetailedRange, and jump directly to Stage 9 (Implementation Readiness Test).
- Preset 0:
Step 3: Semantic Split Discovery
- Split Bypass Check: If Preset 2 (
Feature spec only) was selected, skip this step completely. SetFeatureRangeto cover the entire document (lines 1 through End) and proceed directly to Step 4. - Inspect Document: Read
TargetFileto inspect its structure and line count. - Discover Split Boundary: Scan for the primary dividing header
## Detailed Implementation Plan(or standard synonyms:## Implementation Plan,## Work Breakdown,## Implementation Steps).- Standard Layout Detected: If the boundary header is unambiguously
identified at line $L$:
- Automatically assign
FeatureRange = 1..(L-1). - Automatically assign
DetailedRange = L..End. - Output a concise confirmation message to the user in chat:
"Discovered semantic boundary at line L. FeatureRange: 1..(L-1), DetailedRange: L..End." - Proceed directly to Step 4 without presenting a confirmation modal.
- Automatically assign
- Ambiguous Boundary / Multiple Candidate Headers: If multiple
conflicting headers or non-standard structures exist:
- Present a single-select gate (using a structured question tool such
as
ask_questionwithlen(questions) == 1, or plain chat) proposing the most likely split line as Option 0, with Option 1 allowing custom line ranges via write-in.
- Present a single-select gate (using a structured question tool such
as
- No Implementation Plan Found: If the document contains only a
high-level feature specification:
- Notify the user in chat that no implementation plan was detected.
- Assign
FeatureRange = 1..EndandDetailedRange = N/A. - Offer to execute Stages 5–8 (Feature Spec gates) and proceed.
- Standard Layout Detected: If the boundary header is unambiguously
identified at line $L$:
Step 4: Staging Strategy
Once the semantic split and execution preset are confirmed:
- Confirm Review Target: Verify that
FeatureRangeandDetailedRangeare bound. - Dispatch Execution Pipeline:
- Interactive review with all review rubrics: Execute Stage 5 → Stage 6 → Stage 7 → Stage 8 → Stage 9 sequentially.
- Consolidated report with all review rubrics: Run Subflow: Uninterrupted Full Flow.
- Feature spec only: Execute Stage 5 → Stage 6 → Stage 7 → Stage 8, then cleanly halt.
- Implementation plan only: Jump directly to Stage 9 (Implementation Readiness Test).
Subflows
Subflow Checkpoint Gates & Pause/Resume Protocol
All interactive review stages conclude with an explicit single-select gate
(using a structured question tool such as ask_question with
len(questions) == 1, is_multi_select: false, sole tool call in turn, or
plain chat):
- Stage Checkpoint Patterns:
- Stages 5, 6, 8 (Altitude & Comprehension Checkpoints):
- Option 0:
Proceed to next stage: Stage [N+1] ([Next Stage Name])(orConclude review and begin detailed implementation planningfor Stage 8 terminal). - Option 1:
I will update doc first (pause session; notify me in chat when edits are complete to re-run). - Option 2:
Pause Review (save progress and exit).
- Option 0:
- Stages 7, 9 (Remediation & Readiness Checkpoints):
- Option 0:
Proceed to next stage: Stage [N+1] ([Next Stage Name])(orConclude review and finalize documentfor Stage 9 terminal). - Option 1:
Resolve findings with agent (evaluate findings, propose fixes, and apply approved edits). - Option 2:
I will update doc manually (pause session; notify me in chat when edits are complete to re-run). - Option 3:
Pause Review (save progress and exit).
- Option 0:
- Stages 5, 6, 8 (Altitude & Comprehension Checkpoints):
- Resolution Semantics (Option 1 for Stages 7 and 9):
- Hand-off to Resolver: The agent invokes
egm-resolvein the primary Elephant context window on the target range (FeatureRangeorDetailedRange), passing the parsed findings fromcritic_report.mdorimplementation_readiness_report.md. - Resolution Workflow: The Elephant classifies each finding (
PROPOSE FIXvsCONTEST), writesgoldfish_review_report.md, and executes approved edits onTargetFilevia file editing tools. - Convergence: After applying fixes, re-read
TargetFileto recalculate line bounds, and either advance to the next stage or re-run the stage audit (enforcing max 1 re-audit limit).
- Hand-off to Resolver: The agent invokes
- Pause & Resume Semantics (Manual Doc Updates):
- Turn Yield: The agent confirms in chat that the review is paused for manual document edits, and yields execution immediately.
- Resume Notification: When the author replies in chat indicating
edits are complete:
- Re-read
TargetFileto recalculate line shifts. - Re-run the current stage subflow.
- 1-Audit Convergence Cap: Each stage allows a maximum of 1 re-audit. If manual doc updates are requested again after a re-audit, inform the author that the cap is reached, document residual findings as accepted trade-offs, auto-bind Option 0, and advance to the next stage.
- Re-read
- Graceful Halt Semantics (
Pause Review):- Halt execution immediately with zero tools, preserving all report artifacts.
Subflow: Uninterrupted Full Flow
- Uninterrupted Stage Execution: Execute all five review stages in
sequence without interactive checkpoint pauses between steps. For each
stage, write the individual report file to the working directory (or your
harness's artifact directory, if it has one):
- Step 5 (Initial Zoom Out): Spawn
egm-synthesizer(or direct subagent) withReviewers: [egm-zoom-out]onfull file→ writezoom_out_report.md. - Step 6 (Comprehension Test): Spawn
egm-synthesizer(or direct subagent) withReviewers: [egm-comprehension]onFeatureRange&DetailedRange→ writecomprehension_report.md. - Step 7 (Critic Review): Spawn
egm-synthesizer(or direct subagents) withReviewers: [egm-design, egm-structural, egm-style]onFeatureRange→ writecritic_report.md. - Step 8 (Intermediate Zoom Out): Spawn
egm-synthesizer(or direct subagent) withReviewers: [egm-zoom-out]onfull file→ writeintermediate_zoom_out_report.md. - Step 9 (Implementation Readiness Test): Spawn
egm-synthesizer(or direct subagents) withReviewers: [egm-implementation-readiness, egm-codebase-details, egm-style]onDetailedRange→ writeimplementation_readiness_report.md.
- Step 5 (Initial Zoom Out): Spawn
- Cross-Stage Synthesis & Deduplication:
- Collect all findings across the 5 stage reports.
- Consolidate observations into actionable tasks by priority (🔴 Blocker, 🟡 Major, 🟢 Nit).
