What is aibridge-code-index?

A read-only lookup tool for finding code symbols in Unity projects. Unity is a game-development platform, and symbols are named pieces of code such as classes, methods, and interfaces.

Use it to navigate Unity code, find where a symbol is defined or used, identify classes implementing an interface, and inspect related diagnostics.

It helps locate definitions, references, callers, implementations, and diagnostics without searching every source file by hand. It only works when the project's AIBridge Code Index is enabled.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00086	$0.00520
Opus 5	$0.00043	$0.00260
Sonnet 5	$0.00017	$0.00104
Haiku 4.5	$0.00009	$0.00052

Security

Grade A, and why

aibridge-code-index scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

AIBridge Code Index Skill

Run commands from the Unity project root.

CLI Path: ./.aibridge/cli/AIBridgeCLI.exe

Availability Rule: This Skill is installed only when AIBridge/Settings > Code Index > Enable Code Index is enabled. If project rules say Code Index is disabled, or code_index status reports enabled=false or state=disabled, stop using code_index and fall back to rg plus normal file reads.

Operating Rules

code_index is CLI-only, read-only, and does not rename, refactor, or write files.
Use it for symbol lookup and source navigation before broad code edits when semantic lookup is useful.
Trust only results marked semantic=true; fallback text candidates are explicitly marked semantic=false.
If disabled or unavailable, do not retry repeatedly. Use rg, file reads, and regular AIBridge commands.

Commands

$CLI code_index status
$CLI code_index doctor
$CLI code_index warmup
$CLI code_index symbol --query PlayerController
$CLI code_index definition --file Assets/Scripts/Foo.cs --line 42 --column 17
$CLI code_index references --file Assets/Scripts/Foo.cs --line 42 --column 17
$CLI code_index implementations --type Game.IFoo
$CLI code_index derived --type Game.BasePanel
$CLI code_index callers --file Assets/Scripts/Foo.cs --line 42 --column 17
$CLI code_index diagnostics --file Assets/Scripts/Foo.cs

Results include enabled, semantic, source, state, stale, workspaceMode, snapshot metadata, excluded snapshot counts, projectRoot, and solution. Unity can generate/prewarm the snapshot from AIBridge/Settings > Code Index, where PackageCache source indexing and ignored assembly/source-path patterns can also be configured.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
