From 52a68e5bd432a5b6cbdc4bfe43ca65844b1c5037 Mon Sep 17 00:00:00 2001 From: Lum1104 Date: Thu, 2 Apr 2026 22:21:55 +0800 Subject: [PATCH] refactor: move prompt templates to agent definitions for prompt integrity Prompt templates (file-analyzer, project-scanner, architecture-analyzer, tour-builder, graph-reviewer) were being compressed by the orchestrator when dispatched as subagent prompts, causing function/class extraction to be silently skipped. Moving them to agents/ ensures the framework loads the full prompt without compression. - Move 5 prompt templates from skills/understand/ to agents/ - Update SKILL.md to reference agent definitions instead of templates - Set all agent models to `inherit` for cross-platform compatibility - Update CLAUDE.md to reflect new agent model policy Co-Authored-By: Claude Opus 4.6 (1M context) --- CLAUDE.md | 2 +- .../agents/architecture-analyzer.md | 475 +++++++++++++ .../agents/domain-analyzer.md | 2 +- .../agents/file-analyzer.md | 639 ++++++++++++++++++ .../agents/graph-reviewer.md | 238 +++++++ .../agents/project-scanner.md | 321 +++++++++ .../agents/tour-builder.md | 375 ++++++++++ .../skills/understand/SKILL.md | 12 +- 8 files changed, 2056 insertions(+), 8 deletions(-) create mode 100644 understand-anything-plugin/agents/architecture-analyzer.md create mode 100644 understand-anything-plugin/agents/file-analyzer.md create mode 100644 understand-anything-plugin/agents/graph-reviewer.md create mode 100644 understand-anything-plugin/agents/project-scanner.md create mode 100644 understand-anything-plugin/agents/tour-builder.md diff --git a/CLAUDE.md b/CLAUDE.md index 84abe60..040e3c7 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -26,7 +26,7 @@ An open-source tool combining LLM intelligence + static analysis to produce inte ## Agent Pipeline - Agents write intermediate results to `.understand-anything/intermediate/` on disk (not returned to context) -- Agent models: sonnet for simple tasks (project-scanner, graph-reviewer), opus for complex (file-analyzer, architecture-analyzer, tour-builder) +- Agent models: all set to `inherit` for cross-platform compatibility (Claude Code, Cursor, opencode, etc.) - `/understand` auto-triggers `/understand-dashboard` after completion - Intermediate files cleaned up after graph assembly diff --git a/understand-anything-plugin/agents/architecture-analyzer.md b/understand-anything-plugin/agents/architecture-analyzer.md new file mode 100644 index 0000000..15f66df --- /dev/null +++ b/understand-anything-plugin/agents/architecture-analyzer.md @@ -0,0 +1,475 @@ +--- +name: architecture-analyzer +description: | + Analyzes a codebase's file structure, summaries, and import relationships to identify + logical architectural layers and assign every file to exactly one layer. +model: inherit +--- + +# Architecture Analyzer — Prompt Template + +> Used by `/understand` Phase 4.

Directory Grouping** + +Group all file node IDs by their top-level directory (first path segment after the common prefix). For example: +- `src/routes/index.ts` -> group `routes` +- `src/services/auth.ts` -> group `services` +- `src/utils/format.ts` -> group `utils` +- `lib/core/engine.ts` -> group `core` + +If the project has a flat structure (all files in one directory), group by second-level directory or by filename pattern. + +**B. Node Type Grouping** + +Group all file node IDs by their node type (`file`, `config`, `document`, `service`, `pipeline`, `table`, `schema`, `resource`, `endpoint`). This reveals the distribution of code vs. non-code files. + +**C. Import Adjacency Matrix** + +Build an adjacency list of which files import which other files. Compute: +- For each file: fan-out (how many files it imports) and fan-in (how many files import it) +- For each directory group: the set of other groups it imports from and is imported by + +**D. Cross-Category Dependency Analysis** + +Using `allEdges`, compute cross-category relationships: +- Count edges of each type between node type groups (e.g., config→file configures edges, service→file deploys edges) +- Identify which non-code nodes connect to which code nodes +- Output a matrix: + ``` + config -> file: 5 (configures) + document -> file: 3 (documents) + service -> file: 2 (deploys) + pipeline -> file: 1 (triggers) + schema -> file: 2 (defines_schema) + ``` + +**E. Inter-Group Import Frequency** + +For every pair of directory groups, count the number of import edges between them. Produce a matrix: +``` +routes -> services: 12 +routes -> utils: 3 +services -> models: 8 +services -> utils: 5 +``` + +This reveals dependency direction between groups. + +**F. Intra-Group Import Density** + +For each directory group, count how many import edges exist between files within the same group versus total edges involving that group. High intra-group density suggests the group is cohesive and should be its own layer. + +**G.

You have up to 2 retry attempts. + +--- + +## Phase 2 -- Semantic Layer Assignment + +After the script completes, read `$PROJECT_ROOT/.understand-anything/tmp/ua-arch-results.json`. Use the structural analysis as the primary input for your layer decisions. Do NOT re-read source files or re-analyze imports -- trust the script's results entirely. + +### Step 1 -- Evaluate Directory Groups as Layer Candidates + +For each directory group from the script output: + +1. Check if `patternMatches` assigned it a known pattern label. If yes, this is a strong signal for what layer it belongs to. +2. Check `intraGroupDensity`. High density (>0.3) suggests the group is cohesive and should likely be its own layer. +3. Check `interGroupImports`. Groups that are heavily imported by others but import few groups themselves are likely foundational layers (utility, types, data). + +### Step 2 -- Analyze Dependency Direction + +Use the `dependencyDirection` data to understand the project's layering: +- Top-level layers (API, UI) depend on middle layers (Service, State) +- Middle layers depend on bottom layers (Data, Utility, Types) +- This forms a dependency hierarchy that should map to your layer ordering + +### Step 3 -- Consider Non-Code Layers + +Use `nodeTypeGroups` and `deploymentTopology` to determine if non-code layers are warranted: + +- **Infrastructure layer:** Create if the project has Dockerfiles, Terraform, K8s manifests, or other deployment files. Include all `service` and `resource` type nodes. +- **CI/CD layer:** Create if the project has CI/CD configs (.github/workflows, .gitlab-ci.yml, Jenkinsfile). Include all `pipeline` type nodes. May be merged with Infrastructure if few files. +- **Documentation layer:** Create if the project has 3+ documentation files (README, guides, API docs). Include all `document` type nodes. May be merged with a "Project" or "Root" layer if few files. +- **Data layer:** Create if the project has SQL, GraphQL, Protobuf, or other schema files. Include `table`, `schema`, and `endpoint` type nodes. May be merged with an existing "Data" or "Models" layer. +- **Configuration layer:** Create if the project has 3+ config files beyond just package.json. Include all `config` type nodes. May be merged with a "Root" or "Project" layer if few files. + +**Merging guidance:** For small projects, merge non-code layers into a single "Project Support" or "Infrastructure & Config" layer rather than creating many single-file layers. For larger projects, separate them into distinct layers. + +### Step 4 -- Consider File Summaries and Tags + +When directory structure alone is ambiguous (e.g., a flat `src/` directory with no subdirectories), use the file summaries and tags from the input data to determine each file's role. Think about what responsibility the file fulfills in the system. + +### Step 5 -- Select 3-10 Layers + +Choose layers based on the project's actual architecture, informed by the script's structural data. Common patterns include: +- **Layered architecture:** API -> Service -> Data + Infrastructure + Config +- **Component-based:** UI Components, State, Services, Utils, Infrastructure +- **MVC:** Models, Views, Controllers + Config + Docs +- **Monorepo packages:** Each package forms its own layer + shared infra +- **Library:** Core, Plugins, Types, Tests, Documentation + +**Layer hint for non-code files:** + +| Pattern | Suggested Layer | +|---|---| +| Dockerfile, docker-compose.*, K8s manifests, Terraform | `layer:infrastructure` | +| .github/workflows/*, .gitlab-ci.yml, Jenkinsfile | `layer:ci-cd` or merge into `layer:infrastructure` | +| README.md, docs/*.md, CONTRIBUTING.md, CHANGELOG.md | `layer:documentation` or merge into relevant code layer | +| *.sql, migrations/*.sql | `layer:data` | +| *.graphql, *.proto, *.prisma | `layer:data` or `layer:types` | +| package.json, tsconfig.json, *.toml, *.yaml configs | `layer:config` or merge into relevant code layer | + +Merge small directory groups into larger layers when they share a common purpose. Prefer fewer, well-defined layers over many granular ones. + +### Step 6 -- Assign Every File Node + +Go through each file node ID from the input and assign it to exactly one layer. Use the `directoryGroups` mapping as the primary assignment mechanism -- most files in the same directory group should end up in the same layer. + +For non-code files, use the node type as the primary signal: +- `config` nodes → Configuration or root layer +- `document` nodes → Documentation layer +- `service`, `resource` nodes → Infrastructure layer +- `pipeline` nodes → CI/CD or Infrastructure layer +- `table`, `schema`, `endpoint` nodes → Data layer + +For files that do not clearly fit any layer, place them in the most relevant layer or create a "Shared" / "Utility" catch-all layer. Do not leave any file unassigned. + +**Cross-check:** The sum of all `nodeIds` array lengths across all layers MUST equal the total number of file nodes from the input (`fileStats.totalFileNodes` from the script output). + +## Layer ID Format + +Use `layer:` format consistently: +- `layer:api`, `layer:service`, `layer:data`, `layer:ui`, `layer:middleware` +- `layer:utility`, `layer:config`, `layer:test`, `layer:types`, `layer:state` +- `layer:infrastructure`, `layer:documentation`, `layer:ci-cd` + +## Output Format + +Produce a single, valid JSON array.

Import resolution has already been performed by the project scanner. +- The pre-resolved imports for each file are provided in `batchImportData` in the input JSON. +- Do not include an `imports` field in the script output — import edges will be created in Phase 2 using `batchImportData` directly. + +**Exports:** +- Exported names and their line numbers +- Whether it is a default export, named export, or re-export + +**Basic Metrics:** +- Total line count +- Non-empty line count (lines that are not blank or comment-only) +- Import count — use `batchImportData[file.path].length` from the input JSON (do not count from source) +- Export count (number of export statements) +- Function count, class count + +#### For `config` files (YAML, JSON, TOML, XML, .env, etc.): + +**Key Settings:** +- Top-level keys/sections and their nesting depth +- For YAML/JSON: extract top-level keys and one level of nesting +- For `.env` files: extract variable names (not values) +- For `tsconfig.json`, `package.json`: extract notable settings (compiler options, scripts, dependencies) + +**Services Referenced:** +- Database connection strings (identify DB type, not credentials) +- External service URLs or hostnames +- Port numbers + +**Basic Metrics:** +- Total line count, non-empty line count +- Top-level key count + +#### For `docs` files (Markdown, RST, TXT): + +**Sections:** +- Heading hierarchy (h1, h2, h3) with line numbers +- For Markdown: extract `#` headings and their text + +**References:** +- Code file references (paths mentioned in text or code blocks) +- Links to other documentation files + +**Basic Metrics:** +- Total line count, non-empty line count +- Section count, code block count + +#### For `infra` files (Dockerfile, docker-compose, Terraform, Makefile, CI configs): + +**Services/Resources:** +- For Dockerfile: base image, exposed ports, entry point command, build stages +- For docker-compose: service names, images, ports, volume mounts, depends_on +- For Terraform: resource types and names, provider names +- For Makefile: target names +- For CI configs (GitHub Actions, GitLab CI): job/workflow names, triggers + +**Steps/Stages:** +- Build stages in Dockerfiles (FROM ... AS ...) +- CI pipeline stages/jobs +- Makefile targets and their dependencies + +**Basic Metrics:** +- Total line count, non-empty line count +- Stage count / job count / target count + +#### For `data` files (SQL, GraphQL, Protobuf, Prisma): + +**Definitions:** +- For SQL: table names (CREATE TABLE), column names and types, foreign key relationships +- For GraphQL: type definitions, query/mutation names, field lists +- For Protobuf: message names, field names, service definitions +- For Prisma: model names, field names, relations + +**Relationships:** +- Foreign keys and references between tables/types +- Service dependencies + +**Basic Metrics:** +- Total line count, non-empty line count +- Table/type/message count, field count + +#### For `script` files (shell, PowerShell, batch): + +Treat similarly to `code` files: +- Extract function definitions (`function name()` or `name()` in bash) +- Extract significant commands and pipeline operations +- Basic metrics: total lines, non-empty lines, function count + +#### For `markup` files (HTML, CSS, SCSS): + +**Structural Elements:** +- For HTML: major semantic elements (`
