# Phase 8: Screenshot Profiles Verification Report

**Phase Goal:** Per-project named screenshot profiles storing target parameters. Agents define a capture area once and reference it by name in future start_capture calls. New MCP tools: save_screenshot_profile, list_screenshot_profiles, delete_screenshot_profile. Profiles persisted to a project-local JSON file. start_capture extended with screenshot_profile param for profile-based captures with merge semantics.
**Verified:** 2026-04-13T09:10:00Z
**Status:** passed
**Re-verification:** No -- initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Agent can save a named screenshot profile via save_screenshot_profile MCP tool | VERIFIED | `server.registerTool("save_screenshot_profile"` at line 673 of server.ts with full zod schema, validation per target type, source_session support |
| 2 | Agent can list all saved profiles with liveness status via list_screenshot_profiles MCP tool | VERIFIED | `server.registerTool("list_screenshot_profiles"` at line 890 with `test` field computed via `findWindow()` for window/window_region targets |
| 3 | Agent can delete a profile by name via delete_screenshot_profile MCP tool | VERIFIED | `server.registerTool("delete_screenshot_profile"` at line 924, returns available profiles on not-found |
| 4 | Profiles persist across MCP server restarts in a JSON file | VERIFIED | ProfileManager uses `readFile`/`writeFile` with dual-key JSON `{ screenshot: {...}, timing: {...} }`, lazy-load on first access, tested with file round-trip in tests |
| 5 | Agent can auto-populate a profile from a completed capture session | VERIFIED | `saveFromSession()` method in profile-manager.ts (line 166) accepts sessionManager interface, extracts target config from session.config, tested in unit tests |
| 6 | Agent can pass screenshot_profile name to start_capture and get a capture using that profile's target config | VERIFIED | `screenshot_profile` param added to start_capture schema (line 152), profile resolution block at lines 163-198 loads profile and merges via `resolveScreenshotProfile()`, `resolvedArgs` used throughout handler (38 occurrences) |
| 7 | Agent can override individual profile fields with inline params (merge semantics) | VERIFIED | `resolveScreenshotProfile()` in profile-resolver.ts uses nullish coalescing (`??`) for all fields, inline params win. Default target "desktop" treated as non-explicit when profile is used (line 184: `args.target === "desktop" ? undefined : args.target`). 7 resolver tests pass. |
| 8 | Agent gets a structured error with available profile names when referencing a non-existent profile | VERIFIED | Lines 169-181 of server.ts return `{ status: "error", error: "...", available_profiles: [...] }` with `isError: true` when profile not found |

**Score:** 8/8 truths verified

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `src/profiles/profile-types.ts` | ScreenshotProfile interface, ProfilesFileData, slugify | VERIFIED | 53 lines, all exports present, slugify validates empty strings |
| `src/profiles/profile-manager.ts` | ProfileManager class with CRUD + file persistence | VERIFIED | 213 lines, save/get/delete/list/saveFromSession, getProfileManager singleton, lazy-load, dual-key JSON, timing data preservation |
| `src/profiles/profile-resolver.ts` | resolveScreenshotProfile pure function | VERIFIED | 50 lines, ResolvedTargetParams interface, camelCase-to-snake_case mapping, nullish coalescing merge |
| `src/server.ts` | 3 new MCP tool registrations + screenshot_profile in start_capture | VERIFIED | save_screenshot_profile (line 673), list_screenshot_profiles (line 890), delete_screenshot_profile (line 924), screenshot_profile param (line 152), resolvedArgs usage throughout |

### Key Link Verification

| From | To | Via | Status | Details |
|------|----|-----|--------|---------|
| src/server.ts | src/profiles/profile-manager.ts | `getProfileManager()` import | WIRED | Import at line 21, used in save/list/delete tools and start_capture resolution |
| src/server.ts | src/profiles/profile-resolver.ts | `resolveScreenshotProfile` import | WIRED | Import at line 24, called at line 183 in start_capture handler |
| src/server.ts | src/profiles/profile-types.ts | `slugify` import | WIRED | Import at line 23, used in start_capture (line 167) and delete tool (line 934) |
| src/profiles/profile-manager.ts | .screen-timelapse/profiles.json | fs/promises readFile/writeFile | WIRED | readFile in load() (line 58), writeFile in persist() (line 92), mkdir for directory creation (line 87) |
| src/profiles/profile-resolver.ts | src/profiles/profile-types.ts | ScreenshotProfile type import | WIRED | Import at line 8, used as parameter type |

### Data-Flow Trace (Level 4)

| Artifact | Data Variable | Source | Produces Real Data | Status |
|----------|---------------|--------|-------------------|--------|
| profile-manager.ts | profiles Map | JSON file via readFile | Yes -- file read, parsed, Map populated | FLOWING |
| server.ts (list tool) | profilesWithTest | profileManager.list() | Yes -- reads from Map, adds liveness test | FLOWING |
| server.ts (start_capture) | resolvedArgs | resolveScreenshotProfile() | Yes -- merges profile + inline params | FLOWING |

### Behavioral Spot-Checks

| Behavior | Command | Result | Status |
|----------|---------|--------|--------|
| Profile unit tests pass | `npx tsx --test src/profiles/*.test.ts` | 27/27 pass (0 fail) | PASS |
| Build compiles with profile modules | `npx tsup src/index.ts --format esm --outDir dist --clean` | Build success in 18ms | PASS |
| Profile module exports correct functions | grep for export statements | All expected exports found | PASS |

### Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|------------|-------------|--------|----------|
| PROF-01 | 08-01 | Not defined in REQUIREMENTS.md | ORPHANED | Requirement ID referenced in ROADMAP.md and plan frontmatter but not defined in REQUIREMENTS.md |
| PROF-02 | 08-01 | Not defined in REQUIREMENTS.md | ORPHANED | Same -- no PROF-* entries exist in REQUIREMENTS.md |
| PROF-03 | 08-01 | Not defined in REQUIREMENTS.md | ORPHANED | Same |
| PROF-04 | 08-01 | Not defined in REQUIREMENTS.md | ORPHANED | Same |
| PROF-05 | 08-02 | Not defined in REQUIREMENTS.md | ORPHANED | Same |
| PROF-06 | 08-01 | Not defined in REQUIREMENTS.md | ORPHANED | Same |

**Note:** All 6 PROF-* requirement IDs are referenced in ROADMAP.md Phase 8 and plan frontmatter but have no corresponding entries in REQUIREMENTS.md. The requirement definitions need to be added. This is a documentation gap, not an implementation gap -- the implementation fully satisfies the phase goal as described in ROADMAP.md.

### Anti-Patterns Found

| File | Line | Pattern | Severity | Impact |
|------|------|---------|----------|--------|
| (none) | -- | -- | -- | No anti-patterns found in profile module files |

No TODO/FIXME/placeholder/stub patterns found in any of the 6 profile source files. No empty implementations or hardcoded empty data.

### Human Verification Required

No human verification items identified. All truths are verifiable through code inspection and automated tests.

### Gaps Summary

No gaps found. All 8 must-haves verified at all levels (exists, substantive, wired, data flowing). All 27 tests pass. Build compiles cleanly.

The only documentation issue is that PROF-01 through PROF-06 requirement IDs are not defined in REQUIREMENTS.md. This does not block goal achievement but should be addressed for traceability.
