The file
We split this skill into the rules it gives an agent
10 rules. About 0 are common, 8 are distinctive, and 2 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈8
Distinctive · estimate
This author's own choices. Worth a look.
2
Very specific
Tied to their project's names, files or tools. Probably skip.

Before ending a session, verify:
≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.

Project Context Sync
Keep a single source of truth for project status by updating a shared context file at the end of every work session.
When to Use
- End of any work session (chat, coding, planning)
- After completing a milestone or deliverable
- When a project changes phase (e.g. Phase A to Phase B)
- Before handing off work to another agent or team member
- After merging a significant PR or cutting a release
Status File
Maintain a context/status.md (or equivalent) at the repository root with at minimum:
| Column | Content |
| Project | Name of the project or workstream |
| Phase | Current phase (e.g. Phase A, Phase B, GA) |
| Last Milestone | Most recent completed deliverable with version or PR reference |
| Next Steps | 1-3 concrete, actionable items (see rules below) |
Include a Last updated line immediately below the table with the date and a brief label (e.g. YYYY-MM-DD (topic-label)).
Rules
1. Update on Every Session End
The status file MUST be updated at the end of every work session that touches any tracked project. Skipping an update means the next session starts with stale context.
2. Next Steps MUST Be Specific and Actionable
Each next step MUST describe a concrete action that someone can start immediately.
Good:
- "Create Prisma migration for
topicstable with title, created_at, user_id columns" - "Configure
OPENAI_API_KEYin repo secrets viasetup-gh-secrets.sh" - "Write Post 1 draft covering gateway evaluation criteria"
Bad:
- "Work on topics"
- "Set up keys"
- "Continue blog"
3. Link to Plan Files When In Progress
If a task references a plan or issue, link to it so the next session can pick up without searching.
| AI Gateway | Phase A | Evaluation in progress | [confirm-gateway-choice](path/to/plan-file.md): Complete evaluation |4. Update Phase and Milestone Accurately
- Increment the phase only when its exit criteria are met.
- The milestone field reflects what was completed, not what is in progress.
- If a release was cut, include the version:
v0.2.0 released — CI setup + README.
5. Touch Only Projects You Changed
Do not update rows for projects that were not touched in the current session.
6. Preserve the Format
Keep the status table in the same Markdown format so it can be parsed by scripts or other agents. Do not add free-form prose above the table or between the table and the Last updated line.
Checklist
Before ending a session, verify:
- Every project touched in this session has an updated row in the status table
Last Milestonereflects the most recent completed deliverableNext Stepscontains 1-3 specific, actionable items (not vague descriptions)- Plan links are included for any in-progress tracked work
Last updateddate and label are current- No untouched projects were modified
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
