What it does

Weekly Checkin is an agent skill from huytieu/COG-second-brain. Cross-domain pattern analysis and strategic reflection for weekly review

Its SKILL.md is about 3.5k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Knowledge Management, covering Journaling and reflection. The repository describes itself as: Self-evolving second brain with 35 AI skills, 10 agents, and people CRM. Closed-loop harness: a V-model verification lifecycle where the worker never grades its own homework… The licence is MIT.

When your agent uses it

  • Tasks that involve Journaling and reflection

Example prompts

  • “/weekly-checkin”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Gather Context
  2. Guided Reflection
  3. Generate Weekly Check-in Document
  4. Confirm Completion

What it can do on your machine

Read from SKILL.md and the folder at commit 36ac9d7. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Weekly Checkin loads about 3.5k tokens when it runs. Until then it costs about 22 tokens; SKILL.md has 1,155 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~22
When it runs · the whole SKILL.md, loaded when a task matches
~3.5k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

COG Weekly Check-in Skill

Purpose

Comprehensive weekly review and analysis integrating insights across all domains (personal, professional, projects) with pattern recognition and strategic planning.

When to Invoke

  • User wants to do their weekly review
  • User says "weekly checkin", "weekly review", "reflect on my week"
  • End of week reflection time
  • User wants to analyze patterns across the week

Agent Mode Awareness

Check agent_mode in 00-inbox/MY-PROFILE.md frontmatter:

  • If agent_mode: team — delegate domain-specific analysis to sub-agents (e.g., one for personal patterns, one for professional review, one per active project). Each agent scans relevant braindumps/briefs and returns insights. Combine into the weekly synthesis.
  • If agent_mode: solo (default) — handle all scanning and analysis directly in the conversation. No delegation.

Pre-Flight Check

Check for user profile (optional but enhances experience):

  1. Look for 00-inbox/MY-PROFILE.md in the vault
  2. If found:
    • Read user's name for personalization
    • Read active projects to review project-specific progress
    • Tailor reflection questions to user's role and projects

Get current timestamp (REQUIRED before generating any files):

  1. Run date '+%Y-%m-%d %H:%M' using Bash to get the actual current date and time
  2. Store this value and use it for the created: frontmatter field
  3. NEVER guess or fabricate the time — always use the value returned by the date command

Process Flow

1. Gather Context

Scan recent files from the past week:

  • Daily briefs in 01-daily/briefs/
  • Braindumps in 02-personal/braindumps/, 03-professional/braindumps/, 04-projects/*/braindumps/
  • Previous check-ins in 01-daily/checkins/

If MY-PROFILE.md available:

  • Use user's name for personalization
  • Reference their active projects
  • Tailor questions to their role
2. Guided Reflection

Lead user through reflection questions in a warm, conversational tone:

Overall Week Assessment

Ask:

  • "How would you rate this week on a 1-5 scale? Why that rating?"
  • "What were your biggest wins this week?"
  • "What were your main challenges?"

Listen for:

  • Overall sentiment and energy
  • Key accomplishments they're proud of
  • Obstacles they faced
  • Emotional tone of the week
Domain Reviews

Personal Domain: Ask:

  • "How did you take care of yourself this week?"
  • "Any personal growth or insights?"
  • "How were your energy levels and well-being?"

Professional Domain: Ask:

  • "What did you accomplish at work? Any standout moments?"
  • "How did things go with your team or colleagues?"
  • "Any professional development or learning?"

Projects Domain (if applicable): For each active project from MY-PROFILE.md: Ask:

  • "How did [project name] progress this week?"
  • "What moved forward? What's blocking you?"
  • "Any new insights or direction changes?"
Pattern Recognition

Ask:

  • "Looking at your braindumps this week, did you notice any recurring themes?"
  • "How did your energy levels vary throughout the week?"
  • "Any connections between different areas of your life - personal, professional, projects?"
  • "What surprised you this week?"

Help identify:

  • Themes they might not see themselves
  • Patterns across domains
  • Evolution of thinking
  • Cross-domain connections
Forward Planning

Ask:

  • "What are your top 3 priorities for next week?"
  • "Anything from this week you want to carry forward?"
  • "What do you want to do differently next week?"
  • "What success would look like next week?"

Help with:

  • Clarifying priorities
  • Being specific about goals
  • Identifying experiments to try
  • Setting measurable outcomes

4. Confirm Completion

After creating the check-in:

  • Confirm file was created
  • Show user: "Weekly check-in saved to [file path]"
  • Highlight 1-2 key patterns spotted
  • Offer to review patterns across multiple weeks if helpful
  • Ask if they want to capture any follow-up thoughts via braindump skill

Loop Engineering

The weekly check-in pairs a per-domain scan loop with a human-in-the-loop reflection, gated by a coverage checklist. See .claude/skills/loop-engineering/SKILL.md for the shared vocabulary.

The scan loop (gather phase): scan each domain's recent files → aggregate candidate themes → run the coverage check → if a domain or active project is thin, scan it more deeply before moving on. In agent_mode: team, fan this out as one worker per domain (orchestrator-workers); each returns its themes only.

The reflection loop (guided phase): this is human-in-the-loop by design. Ask, listen, reflect back, ask the targeted follow-up. The loop continues until the coverage checklist is satisfied or the user signals they are done. Do not rush it and do not force positivity.

The verifier (deterministic checklist):

  • Every active project in MY-PROFILE.md has a Projects section addressed.
  • Each domain (personal / professional / projects) was actually covered, not skipped.
  • At least the recurring themes the scan surfaced were raised with the user.

Termination conditions (layered):

  • Coverage complete: checklist satisfied → generate the check-in document.
  • User signals done: respect it; generate with what you have and note any thin spots.
  • No-progress / terse answers: if follow-ups keep returning little, stop probing that thread and offer to skip it rather than grinding. Escalation here means handing the choice back to the user.

Patterns: orchestrator-workers (team-mode domain scans) + human-in-the-loop (reflection) + completeness checklist (the verifier).

In-loop context: capture answers into the check-in structure as the conversation goes, so a long reflection does not lose early answers.

Conversational Guidelines

Do:
  • Have a warm, empathetic, conversational tone
  • Ask thoughtful follow-up questions based on user's answers
  • Help identify patterns they might not see themselves
  • Be honest and objective in summarizing their reflections
  • Celebrate wins genuinely and specifically
  • Acknowledge challenges without sugar-coating or minimizing
  • Show curiosity about their experiences
  • Reflect back what you're hearing for validation
Don't:
  • Rush through the questions
  • Make assumptions about what matters to them
  • Judge their answers or week rating
  • Over-structure their free-form reflections
  • Force positivity if they had a tough week
  • Dismiss their challenges or concerns
  • Skip the emotional/energy assessment
  • Be clinical or robotic in tone

Pattern Recognition Techniques

Frequency Analysis
  • What themes come up repeatedly across braindumps?
  • Which topics get the most attention?
  • What's mentioned but not deeply explored?
Temporal Clustering
  • What insights emerged together in time?
  • How did thinking evolve from Monday to Friday?
  • Were there inflection points during the week?
Domain Correlation
  • What patterns cross personal/professional/project boundaries?
  • How do domains influence each other?
  • Where is there alignment or tension?
Contradiction Analysis
  • Where does thinking conflict with actions?
  • Are there competing priorities?
  • What tensions exist between domains?
Energy Pattern Detection
  • When was energy highest/lowest?
  • What activities energized vs. drained?
  • How did energy affect productivity and insights?
