weekly-checkinCross-domain pattern analysis and strategic reflection for weekly review
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.
4 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 36ac9d7. It shows what the files ask for, not the result of running them.
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.
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.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
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.
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.
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.

After creating the check-in:
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):
MY-PROFILE.md has a Projects section addressed.Termination conditions (layered):
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.

Cross-domain pattern analysis and strategic reflection for weekly review. Weekly Checkin is an agent skill from huytieu/COG-second-brain.
Weekly Checkin fits situations like: tasks that involve Journaling and reflection.
Run `npx skills add huytieu/COG-second-brain --skill weekly-checkin -a claude-code`. Or copy the skill folder (skills/weekly-checkin in huytieu/COG-second-brain) into .claude/skills/weekly-checkin in your project. Claude Code loads it when a task matches its description.
Run `npx skills add huytieu/COG-second-brain --skill weekly-checkin -a codex`. Or copy the skill folder (skills/weekly-checkin in huytieu/COG-second-brain) into .agents/skills/weekly-checkin in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add huytieu/COG-second-brain --skill weekly-checkin -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/weekly-checkin, .gemini/skills/weekly-checkin, .github/skills/weekly-checkin and .opencode/skills/weekly-checkin in your project.
SKILL.md names no scripts, command-line tools or credentials: Weekly Checkin is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Weekly Checkin is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 3.5k tokens (SKILL.md is roughly 14k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Weekly Checkin: LLM Wiki (lewislulu/llm-wiki-skill, 655 stars), Munger Perspective (alchaincyf/munger-skill, 379 stars), Letterboxd Diary (joe-bell/skills, 211 stars) and Em Grid Scorer (manager-dot-dev/manager-skills, 114 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
