+description: "This skill should be used when code search is needed (whether explicitly requested or as part of completing a task), when indexing the codebase after changes, or when the user asks about ccc, cocoindex-code, or the codebase index. Trigger phrases include 'search the codebase', 'find code related to', 'update the index', 'ccc', 'cocoindex-code'."
+---
+
+# ccc - Semantic Code Search & Indexing
+
+`ccc` is the CLI for CocoIndex Code, providing semantic search over the current codebase and index management.
+
+## Ownership
+
+The agent owns the `ccc` lifecycle for the current project — initialization, indexing, and searching. Do not ask the user to perform these steps; handle them automatically.
+
+- **Initialization**: If `ccc search` or `ccc index` fails with an initialization error (e.g., "Not in an initialized project directory"), run `ccc init` from the project root directory, then `ccc index` to build the index, then retry the original command.
+- **Index freshness**: Keep the index up to date by running `ccc index` (or `ccc search --refresh`) when the index may be stale — e.g., at the start of a session, or after making significant code changes (new files, refactors, renamed modules). There is no need to re-index between consecutive searches if no code was changed in between.
+- **Installation**: If `ccc` itself is not found (command not found), refer to [management.md](references/management.md) for installation instructions and inform the user.
+
+## Searching the Codebase
+
+To perform a semantic search:
+
+```bash
+ccc search <query terms>
+```
+
+The query should describe the concept, functionality, or behavior to find, not exact code syntax. For example:
+
+```bash
+ccc search database connection pooling
+ccc search user authentication flow
+ccc search error handling retry logic
+```
+
+### Filtering Results
+
+- **By language** (`--lang`, repeatable): restrict results to specific languages.
+
+  ```bash
+  ccc search --lang python --lang markdown database schema
+  ```
+
+- **By path** (`--path`): restrict results to a glob pattern relative to project root. If omitted, defaults to the current working directory (only results under that subdirectory are returned).
+
+  ```bash
+  ccc search --path 'src/api/*' request validation
+  ```
+
+### Pagination
+
+Results default to the first page. To retrieve additional results:
+
+```bash
+ccc search --offset 5 --limit 5 database schema
+```
+
+If all returned results look relevant, use `--offset` to fetch the next page — there are likely more useful matches beyond the first page.
+
+### Working with Search Results
+
+Search results include file paths and line ranges. To explore a result in more detail:
+
+- Use the editor's built-in file reading capabilities (e.g., the `Read` tool) to load the matched file and read lines around the returned range for full context.
+- When working in a terminal without a file-reading tool, use `sed -n '<start>,<end>p' <file>` to extract a specific line range.
+
+## Settings
+
+To view or edit embedding model configuration, include/exclude patterns, or language overrides, see [settings.md](references/settings.md).
+
+## Management & Troubleshooting
+
+For installation, initialization, daemon management, troubleshooting, and cleanup commands, see [management.md](references/management.md).

+# ccc Management
+
+## Installation
+
+Install CocoIndex Code via pipx. Two install styles:
+
+```bash
+pipx install 'cocoindex-code[full]'      # batteries included (local embeddings via sentence-transformers)
+pipx install cocoindex-code              # slim (LiteLLM-only; requires a cloud embedding provider + API key)
+```
+
+The `[full]` extra pulls in `sentence-transformers` so the first-run default (local embeddings, no API key) works out of the box. The slim install is for environments where you don't want the torch/transformers deps and plan to use a LiteLLM-supported cloud provider instead.
+
+To upgrade to the latest version:
+
+```bash
+pipx upgrade cocoindex-code
+```
+
+After installation, the `ccc` command is available globally.
+
+## Project Initialization
+
+Run from the root directory of the project to index:
+
+```bash
+ccc init
+```
+
+**First run (global settings don't exist yet)** — `ccc init` prompts interactively for the embedding provider (sentence-transformers / litellm) and model, then runs a one-off test embed via the daemon to confirm the model works. Accept the defaults for the sentence-transformers path, or pick litellm and enter a model identifier.
+
+**Subsequent runs** (global settings already exist) — prompts are skipped; only project settings and `.gitignore` are set up.
+
+To skip the interactive prompts on the first run (e.g. in a script or container), pass `--litellm-model MODEL`:
+
+```bash
+ccc init --litellm-model openai/text-embedding-3-small
+```
+
+This is also the only way to pick a LiteLLM model when stdin isn't a TTY and you've done a slim install.
+
+`ccc init` creates:
+- `~/.cocoindex_code/global_settings.yml` (user-level, embedding config + env vars).
+- `.cocoindex_code/settings.yml` (project-level, include/exclude patterns).
+
+If `.git` exists in the directory, `.cocoindex_code/` is automatically added to `.gitignore`.
+
+Use `-f` to skip the confirmation prompt if `ccc init` detects a potential parent project root.
+
+After initialization, edit the settings files if needed (see [settings.md](settings.md) for format details), then run `ccc index` to build the initial index. If the model test printed `[FAIL]` during `init`, edit `global_settings.yml` (and optionally add API keys under the commented `envs:` block) and verify with `ccc doctor` before indexing.
+
+## Troubleshooting
+
+### Diagnostics
+
+Run `ccc doctor` to check system health end-to-end:
+
+```bash
+ccc doctor
+```
+
+This checks global settings, daemon status, embedding model (runs a test embedding), and — if run from within a project — file matching (walks files using the same logic as the indexer) and index status. Results stream incrementally. Always points to `daemon.log` at the end for further investigation.
+
+### Checking Project Status
+
+To view the current project's index status:
+
+```bash
+ccc status
+```
+
+This shows whether indexing is ongoing and index statistics.
+
+### Daemon Management
+
+The daemon starts automatically on first use. To check its status:
+
+```bash
+ccc daemon status
+```
+
+This shows whether the daemon is running, its version, uptime, and loaded projects.
+
+To restart the daemon (useful if it gets into a bad state):
+
+```bash
+ccc daemon restart
+```
+
+To stop the daemon:
+
+```bash
+ccc daemon stop
+```
+
+## Cleanup
+
+To reset a project's index (removes databases, keeps settings):
+
+```bash
+ccc reset
+```
+
+To fully remove all CocoIndex Code data for a project (including settings):
+
+```bash
+ccc reset --all
+```
+
+Both commands prompt for confirmation. Use `-f` to skip.

+# ccc Settings
+
+Configuration lives in two YAML files, both created automatically by `ccc init`.
+
+## User-Level Settings (`~/.cocoindex_code/global_settings.yml`)
+
+Shared across all projects. Controls the embedding model and extra environment variables for the daemon.
+
+```yaml
+embedding:
+  provider: sentence-transformers   # or "litellm" (default when provider is omitted)
+  model: Snowflake/snowflake-arctic-embed-xs
+  device: mps                       # optional: cpu, cuda, mps (auto-detected if omitted)
+  min_interval_ms: 300              # optional: pace LiteLLM embedding requests to reduce 429s; defaults to 5 for LiteLLM
+
+envs:                               # extra environment variables for the daemon
+  OPENAI_API_KEY: your-key          # only needed if not already in the shell environment
+```
+
+### Fields
+
+| Field | Description |
+|-------|-------------|
+| `embedding.provider` | `sentence-transformers` for local models, `litellm` (or omit) for cloud/remote models |
+| `embedding.model` | Model identifier — format depends on provider (see examples below) |
+| `embedding.device` | Optional. `cpu`, `cuda`, or `mps`. Auto-detected if omitted. Only relevant for `sentence-transformers`. |
+| `embedding.min_interval_ms` | Optional. Minimum delay between LiteLLM embedding requests in milliseconds. Defaults to `5` for LiteLLM and is ignored by `sentence-transformers`. Set explicitly to override the default. |
+| `envs` | Key-value map of environment variables injected into the daemon. Use for API keys not already in the shell environment. |
+
+### Embedding Model Examples
+
+**Local (sentence-transformers, no API key needed):**
+
+```yaml
+embedding:
+  provider: sentence-transformers
+  model: Snowflake/snowflake-arctic-embed-xs        # default, lightweight
+```
+
+```yaml
+embedding:
+  provider: sentence-transformers
+  model: nomic-ai/CodeRankEmbed                     # better code retrieval, needs GPU (~1 GB VRAM)
+```
+
+**Ollama (local):**
+
+```yaml
+embedding:
+  model: ollama/nomic-embed-text
+```
+
+**OpenAI:**
+
+```yaml
+embedding:
+  model: text-embedding-3-small
+  min_interval_ms: 300
+envs:
+  OPENAI_API_KEY: your-api-key
+```
+
+**Gemini:**
+
+```yaml
+embedding:
+  model: gemini/gemini-embedding-001
+envs:
+  GEMINI_API_KEY: your-api-key
+```
+
+**Voyage (code-optimized):**
+
+```yaml
+embedding:
+  model: voyage/voyage-code-3
+envs:
+  VOYAGE_API_KEY: your-api-key
+```
+
+For the full list of supported cloud providers and model identifiers, see [LiteLLM Embedding Models](https://docs.litellm.ai/docs/embedding/supported_embedding).
+
+### Important
+
+Switching embedding models changes vector dimensions — you must re-index after changing the model:
+
+```bash
+ccc reset && ccc index
+```
+
+## Project-Level Settings (`<project>/.cocoindex_code/settings.yml`)
+
+Per-project. Controls which files to index. Created by `ccc init` and automatically added to `.gitignore`.
+
+```yaml
+include_patterns:
+  - "**/*.py"
+  - "**/*.js"
+  - "**/*.ts"
+  # ... (sensible defaults for 28+ file types)
+
+exclude_patterns:
+  - "**/.*"              # hidden directories
+  - "**/__pycache__"
+  - "**/node_modules"
+  - "**/dist"
+  # ...
+
+language_overrides:
+  - ext: inc             # treat .inc files as PHP
+    lang: php
+```
+
+### Fields
+
+| Field | Description |
+|-------|-------------|
+| `include_patterns` | Glob patterns for files to index. Defaults cover common languages (Python, JS/TS, Rust, Go, Java, C/C++, C#, SQL, Shell, Markdown, PHP, Lua, etc.). |
+| `exclude_patterns` | Glob patterns for files/directories to skip. Defaults exclude hidden dirs, `node_modules`, `dist`, `__pycache__`, `vendor`, etc. |
+| `language_overrides` | List of `{ext, lang}` pairs to override language detection for specific file extensions. |
+
+### Editing Tips
+
+- To index additional file types, append glob patterns to `include_patterns` (e.g. `"**/*.proto"`).
+- To exclude a directory, append to `exclude_patterns` (e.g. `"**/generated"`).
+- After editing, run `ccc index` to re-index with the new settings.

+## Context
+
+当前 `polling_carddata` 链路已经能正确更新卡维度流量读数，但套餐扣减存在两个缺口：
+
+1. 载体路由缺口：扣减调用固定使用 `carrier_type=iot_card`，导致绑定设备且套餐挂在 `device_id` 时无法命中可扣套餐。
+2. 精度缺口：上游流量读数是 `float64 MB`，扣减时转 `int64`，会丢失 `<1MB` 的高频增量。
+
+系统现有分层为 Handler → Service → Store → Model，扣减核心在 `UsageService.DeductDataUsage`，轮询和手动刷新都依赖该能力。为避免分叉逻辑，本次设计将修复集中在 Service 层并保持调用链兼容。
+
+## Goals / Non-Goals
+
+**Goals:**
+- 修复绑定设备卡的套餐扣减命中问题，保证设备级套餐能被正确扣减。
+- 修复小数增量丢失问题，保证高频小流量场景下长期扣减准确。
+- 明确流量字段语义：`current_month_usage_mb` 与运营商周期口径解耦。
+- 保持现有 API、数据库表结构和任务调度不破坏。
+
+**Non-Goals:**
+- 不重构轮询体系，不调整 Asynq 任务类型。
+- 不新增数据库迁移。
+- 不改变套餐优先级策略（仍是加油包优先、主套餐兜底）。
+- 不新增自动化测试范围（按项目约束，仅提供手动验证方案）。
+
+## Decisions
+
+### 决策 1：载体命中策略下沉到 UsageService
+
+- 方案：`DeductDataUsage` 先按请求载体查询生效套餐；若 `iot_card` 未命中且该卡存在有效设备绑定，则回退按 `device` 查询并扣减。
+- 理由：
+  - 轮询与手动刷新共用一套扣减逻辑，避免在多个 Handler/Service 重复实现路由判断。
+  - 符合分层约束，业务判断集中在 Service 层，Store 层保持通用查询职责。
+- 备选方案：在 `polling_carddata_handler` 单点改传 `device`。
+  - 未采用原因：手动刷新链路仍会错；后续新入口也会重复踩坑。
+
+### 决策 2：小数增量使用“余量累加”而非直接四舍五入
+
+- 方案：保留扣减单位为整数 MB，但把小数部分按载体维度写 Redis 余量键（带 TTL）；后续增量先与余量相加，再计算本次可扣整数 MB。
+- 理由：
+  - 不改变 `tb_package_usage.data_usage_mb` 的整数结构，兼容现有统计与查询。
+  - 避免每次四舍五入带来的长期偏差。
+  - Redis 读写轻量，满足轮询高频场景性能要求。
+- 备选方案：直接把 `data_usage_mb` 改为小数。
+  - 未采用原因：涉及模型、查询、统计口径和历史数据兼容，变更面过大。
+
+### 决策 3：字段口径保持双轨，不再混用
+
+- 方案：
+  - `current_month_usage_mb`：继续定义为“系统自然月累计（卡维度）”。
+  - `last_gateway_reading_mb`：用于表达“运营商当前周期累计读数（卡维度）”。
+- 理由：
+  - 运营商重置日可能不是每月 1 号，不能用自然月字段替代运营商周期口径。
+  - 绑定设备不改变流量采集主体，流量仍来自卡 ICCID。
+- 备选方案：让 `current_month_usage_mb` 直接改为运营商周期口径。
+  - 未采用原因：会破坏现有自然月统计语义，影响已有展示与分析逻辑。
+
+## Risks / Trade-offs
+
+- 风险：余量键读写失败时会影响小数累计精度。
+  - Mitigation：失败仅降级为“本次不累计小数”，并记录告警日志，主流程不中断。
+
+- 风险：`iot_card -> device` 回退可能在极端并发下出现重复判断。
+  - Mitigation：扣减仍在事务内按当前生效套餐计算，保持幂等结果。
+
+- 风险：前端继续误用 `current_month_usage_mb` 作为运营商周期口径。
+  - Mitigation：在 spec 和接口描述中显式标注口径，前端改读 `last_gateway_reading_mb`。
+
+## Migration Plan
+
+1. 先上线 Service 层扣减修复（载体回退 + 小数余量）。
+2. 通过日志与数据库手动核对重点卡（绑定设备卡、低流量高频卡）。
+3. 前端切换运营商周期展示口径到 `last_gateway_reading_mb`。
+4. 观察 1-2 个运营商结算周期，无异常后关闭问题。
+
+回滚策略：
+- 若出现异常，可回滚到旧版本代码；该变更无 DB schema 迁移，不涉及数据结构回滚。
+
+## Open Questions
+
+- 余量 Redis 键 TTL 的最终值（建议 7 天）是否需要按运营商周期动态设置。
+- 是否需要在管理端 realtime-status 直接返回 `last_gateway_reading_mb`（当前先由前端按现有可用字段接入）。

+## Why
+
+当前线上存在“卡流量已同步但套餐流量不变化”的问题，导致计费与停复机判断失真。该问题集中出现在绑定设备的卡和小流量高频上报场景，已经影响流量扣减准确性，需要优先修复。
+
+## What Changes
+
+- feature-001-traffic-deduction-carrier-routing：修正轮询流量扣减时的载体路由逻辑，避免固定按 `iot_card` 扣减导致设备级套餐无法命中。
+- feature-002-traffic-deduction-fractional-precision：修正流量扣减精度，消除 `float64 -> int64` 截断造成的 `<1MB` 增量长期丢失。
+- feature-003-traffic-field-semantics-clarify：明确字段语义与展示口径：
+  - `current_month_usage_mb`：系统自然月累计流量（卡维度）
+  - `last_gateway_reading_mb`：运营商当前周期累计读数（卡维度）
+- 保持现有分层架构与任务链路不变（Handler → Service → Store → Model），仅调整扣减判定与数据口径说明；无 BREAKING API 变更。
+
+## Capabilities
+
+### New Capabilities
+- 无
+
+### Modified Capabilities
+- `polling-task-handlers`：`polling_carddata_handler` 在触发套餐扣减时，需支持“卡绑定设备时按设备载体命中套餐”而非固定卡载体。
+- `package-usage-priority`：`DeductDataUsage` 需支持小数 MB 增量累计后扣减，保证小流量高频上报场景下扣减准确。
+- `asset-queries`：资产流量字段语义说明补充，避免将 `current_month_usage_mb` 误用为运营商周期口径。
+
+## Impact
+
+- 受影响代码：
+  - `internal/task/polling_carddata_handler.go`
+  - `internal/service/package/usage_service.go`
+  - `internal/service/iot_card/service.go`
+  - `internal/model/dto/asset_dto.go`（描述语义）
+- 受影响数据：
+  - `tb_package_usage.data_usage_mb` 的增长将更贴近上游真实增量（尤其是 <1MB 高频增量场景）
+- API 兼容性：
+  - 无接口路径和结构变更
+  - 前端展示口径建议改为读取 `last_gateway_reading_mb` 表达“运营商周期累计流量”
+- 依赖与基础设施：无新增外部依赖、无数据库迁移。
