project-context（项目背景）

<quick_start> Session start: Load <project-root>/.claude/PROJECT_CONTEXT.md, verify against git status

Session end: Update context file with completed TODOs, clear previous session's Done list

Context file location: <project-root>/.claude/PROJECT_CONTEXT.md

Triggers: "load context", "save context", "done for today", "switch to [project]" </quick_start>

<success_criteria> Context management is successful when:

• Project detected from pwd (Claude Code) or user input (Claude Desktop)
• Context file matches current project (header verified against folder name)
• Git state verified against context (branch, recent commits)
• Done list cleared each new session (prevents accumulation)
• Context saved before session ends </success_criteria>

MANDATORY: Project Detection (Run First)

Before ANY other action, identify which project the user is in:

Claude Code (Terminal)

pwd  # Get current working directory

1. Run pwd to get current directory
2. Extract project name from path (last folder name)
3. Load <pwd>/.claude/PROJECT_CONTEXT.md
4. VERIFY: Does the # <project-name> header match the folder name?

- YES → Display context and proceed - NO → WARN: "Context mismatch! File says [X] but you're in [Y]. Regenerating..." - FILE MISSING → Auto-generate (see below)

Claude Desktop (No Terminal)

If pwd is unavailable (Claude Desktop environment):

1. Check if user already specified a project in their message
2. If not, ASK: "Which project are you working on today?"
3. Use the projects list at reference/projects-list.md if available
4. Load: /Users/tmkipper/Desktop/tk_projects/{project-name}/.claude/PROJECT_CONTEXT.md

To switch projects: User says "switch to [project-name]" or "working on [project]"

On Session Start

After project detection:

1. Load Context File

<project-root>/.claude/PROJECT_CONTEXT.md

2. Verify Against Git State

git status            # Current branch, modified files
git log --oneline -5  # Recent commits

Flag discrepancies:

• TODO marked done in commits? → Move to "Done"
• Branch changed? → Update context header
• Stale info? → Remove it

3. Display to User

Show a brief summary:

📍 Project: [name]
🌿 Branch: [branch]
📅 Last updated: [date]

Focus items: [count]

On Session End

Triggers: "done", "end session", "save context", "done for today"

1. Review conversation for completed work
2. Update PROJECT_CONTEXT.md:

- Move completed TODOs to "Done (This Session)" - Update Status based on commits made - Preserve untouched Focus items - Clear previous session's Done list (prevents accumulation) - Update timestamp

1. Show user the updated context

Auto-Generate Context

When no PROJECT_CONTEXT.md exists, create from:

1. .claude/CLAUDE.md or CLAUDE.md (project docs)
2. git log --oneline -5 (recent activity)
3. git status (current state)
4. package.json / pyproject.toml / requirements.txt (tech stack)

Write to: <project-root>/.claude/PROJECT_CONTEXT.md

Context File Format

See reference/template.md for full template.

# <project-name>

**Branch**: <branch> | **Updated**: <YYYY-MM-DD>

## Status
<2-3 sentences: current state>

## Today's Focus
1. [ ] <task>
2. [ ] <task>

## Done (This Session)
- <populated on session end, cleared on next session start>

## Blockers
<none or list>

## Tech Stack
<single line: Python 3.11 | FastAPI | PostgreSQL>

Key Rules

1. ALWAYS detect project first - Never assume from previous session
2. One project = one context file - No cross-contamination
3. Verify context matches pwd - Warn on mismatch
4. Clear Done list each session - Prevents infinite accumulation
5. Never store data in this SKILL.md - Always use project's own file

Emit Outcome Sidecar

As the final step, write to ~/.claude/skill-analytics/last-outcome-project-context.json:

{"ts":"[UTC ISO8601]","skill":"project-context","version":"1.0.0","variant":"default",
 "status":"[success|partial|error]","runtime_ms":[estimated ms from start],
 "metrics":{"projects_detected":[n],"context_files_updated":[n]},
 "error":null,"session_id":"[YYYY-MM-DD]"}

Use status "partial" if some stages failed but results were produced. Use "error" only if no output was generated. </core_content>
