Walkthrough

This PR duplicates the ANTIGRAVITY_SYSTEM_INSTRUCTION constant export in src/constants.ts and updates src/plugin/request.ts to import this instruction, injecting it into request payloads when headerStyle is "antigravity" while setting requestType to "agent".

Changes

Cohort / File(s)	Summary
Constant definition `src/constants.ts`	Adds `ANTIGRAVITY_SYSTEM_INSTRUCTION` export twice (identical large payloads) (+90 lines).
Antigravity request handling `src/plugin/request.ts`	Imports `ANTIGRAVITY_SYSTEM_INSTRUCTION`; modifies `prepareAntigravityRequest` to inject/merge the instruction into `requestPayload.systemInstruction` when `headerStyle === "antigravity"` (handles object/string/absent cases); sets `requestType: "agent"` in returned payload; injection applied at two normalization points (+32/-1 lines).

In @src/constants.ts:
- Around line 140-228: The ANTIGRAVITY_SYSTEM_INSTRUCTION string has
content-quality problems: fix the numbering duplicate (three "4" entries) under
"Design Aesthetics" so list items are correctly numbered/ordered, change
"Javascript" to "JavaScript" in the "Core" tech stack section, and remove
unintended trailing commas from section headers and list introductions (e.g.,
after "## Technology Stack,", "Design Aesthetics,", and "Implementation
Workflow,", etc.) to make punctuation consistent; keep the overall intent but
trim or consider collapsing non-essential long guidelines to reduce the
constant's size if possible.

ANTIGRAVITY_SYSTEM_INSTRUCTION (149-228)

🔇 Additional comments (4)

src/plugin/request.ts (3)

48-48: LGTM - Import added correctly.

The import of ANTIGRAVITY_SYSTEM_INSTRUCTION is properly structured and positioned with related constants.

1284-1284: LGTM - Request type correctly set.

Setting requestType: "agent" aligns with the CLIProxyAPI v6.6.89 compatibility objective.

1250-1278: Verify the CLIProxyAPI v6.6.89 API contract for systemInstruction.role.

The injection logic sets systemInstruction.role = "user" per CLIProxyAPI v6.6.89 compatibility requirements, but this is non-standard (most APIs expect role: "system"). The input handling (object with parts, plain string, or missing instruction) is correct, and the logic properly prepends the 79-line ANTIGRAVITY_SYSTEM_INSTRUCTION consistently.

However, verify that the Antigravity API contract actually accepts role: "user" for system instructions—this setting is unusual and warrants confirmation against CLIProxyAPI v6.6.89 documentation or API behavior.

The 79-line instruction prepended to every request will increase token consumption. Monitor for context-length errors in production.

149-228: The AI summary incorrectly claims duplication of ANTIGRAVITY_SYSTEM_INSTRUCTION.

Only a single export of ANTIGRAVITY_SYSTEM_INSTRUCTION exists at line 149 in src/constants.ts. The summary's assertion that it was "duplicated twice" is inaccurate.

- Fix 'Javascript' → 'JavaScript' capitalization - Fix duplicate numbering (4, 4) → (4, 5) in Design Aesthetics - Remove trailing commas from section headers and list items - Normalize indentation (tabs → spaces)

In @src/constants.ts:
- Line 150: Replace the incorrect brand capitalization "Google Deepmind" with
the correct "Google DeepMind" wherever that literal appears (e.g., the string on
line containing "You are Antigravity, a powerful agentic AI coding assistant
designed by the Google Deepmind team") so the constant/string uses the official
brand capitalization.

178-178: Fix verb form for parallel structure.

Line 178 uses "Using modern typography" (present participle) while surrounding bullets use imperative verbs ("Avoid", "Use", "Add"). This breaks parallel structure.
✏️ Proposed fix
-   - Using modern typography (e.g., from Google Fonts like Inter, Roboto, or Outfit) instead of browser defaults.

140-148: LGTM! Clear documentation of the new constant.

The comment structure and JSDoc clearly document the purpose and origin of this system instruction constant.

217-228: LGTM! Clear agent behavior guidelines.

The ephemeral message and communication style sections provide clear, actionable guidelines for agent behavior and user interaction.

164-164: Past content issues have been resolved.

The previous review identified several content quality issues that have been addressed in the current version:

Line 164 now correctly uses "JavaScript" (capital S)

Lines 182-183 show correct sequential numbering (items 4 and 5, not three items numbered "4")

Section headers no longer have trailing commas

Good work addressing the feedback!

Also applies to: 182-183

161-207: Consider standardizing markdown header levels.

The instruction uses inconsistent header levels: "Design Aesthetics" uses # (line 174) while "Technology Stack" (line 161), "Implementation Workflow" (line 185), and "SEO Best Practices" (line 207) use ##. Standardizing to the same level would improve consistency when rendered.

140-229: Past issues successfully addressed.

The constant has been properly implemented with the fixes from previous review feedback applied:

"JavaScript" is now correctly capitalized (line 164)

"Google DeepMind" uses proper brand capitalization (line 150)

Numbering under "Design Aesthetics" is now sequential: 4, 5 (lines 182-183)

The large instruction payload matches the CLIProxyAPI v6.6.89 reference and serves the intended purpose of providing identity and guidelines for Antigravity requests.
