AutoContext: Context Operator
Not just a health check — a full operator over everything that shapes context. Three layers by action sensitivity:
| Layer | Examples | Behavior |
|---|---|---|
| Auto-execute | write project memory, update MEMORY.md index | Do it, report path |
| Confirm-first | edit ~/.claude/CLAUDE.md, edit project CLAUDE.md, overwrite/delete existing memory | Show diff, wait for "yes" |
| Suggest-only | /fork, /compact, /btw, new session | Print the exact command to paste |
The harness owns /fork and /compact; this skill cannot invoke them. But it can do everything else and will.
Auto Mode (via Plugin Hook)
When the lovstudio plugin is enabled, a UserPromptSubmit hook monitors transcript size. Above threshold (40+ entries or 150KB+), it injects a lightweight <auto-context> reminder.
When you see <auto-context>:
| Context State | Action |
|---|---|
| Mostly relevant | Continue, say nothing |
| Some stale noise | Mentally deprioritize, proceed |
| Mostly irrelevant | Suggest /fork or /btw with exact command |
| Near capacity | Suggest /compact or /fork with exact command |
Rules:
- 1 sentence max unless acting.
- If context is fine, say nothing.
- Never auto-fork/auto-compact (can't anyway — harness-only).
- Don't mention "AutoContext" unless asked.
Manual Mode (/lovstudio-auto-context [args])
Two call shapes:
A. Bare call — health report + opportunistic memory write
/lovstudio-auto-context- Measure — estimate turns, tool calls, distinct topics
- Assess — healthy / getting noisy / polluted / critical
- Scan recent turns for unpersisted feedback/preferences — if the user stated a rule or preference earlier in the session that should persist to future conversations (typical trigger phrases: "从今以后", "以后都", "所有 X 应该 Y", "别再", "记住"), and no memory was written, auto-execute: write the memory file + update
MEMORY.md. Report the path. - Recommend harness actions if needed (
/fork,/compact,/btw) with the exact command to paste.
Keep to 3-5 lines unless taking confirm-first actions.
B. With arguments — targeted context operation
/lovstudio-auto-context <free-form instruction>Parse the instruction and route to the right action class:
| Instruction pattern | Action | Sensitivity |
|---|---|---|
| "记到全局 / write to global / 加到 ~/.claude/CLAUDE.md" | edit ~/.claude/CLAUDE.md | Confirm-first |
| "记到项目 / 加到项目 CLAUDE.md" | edit project CLAUDE.md | Confirm-first |
| "记住 X / 记到 memory" | write project memory | Auto-execute |
| "忘掉 X / forget X" | remove relevant memory file + index entry | Confirm-first |
| "该分叉了吗 / should I fork" | evaluate + suggest command | Suggest-only |
| "压缩一下 / compact" | suggest /compact with exact syntax | Suggest-only |
Action: Write Project Memory (auto-execute)
Directory: ~/.claude/projects/<project-slug>/memory/ (already exists; do not mkdir).
Procedure:
- Pick filename:
<type>_<topic>.md(e.g.feedback_output_paths.md). - Write with the required frontmatter (
name,description,type). - For
feedback/projecttypes, include**Why:**and**How to apply:**lines. - Update
MEMORY.mdwith one-line pointer under 150 chars. - Report the absolute + relative path.
Action: Edit Global CLAUDE.md (confirm-first)
Target: ~/.claude/CLAUDE.md.
Procedure:
- Read the file.
- Locate the best section for the addition (match existing heading like "输出规范", "网络 / 代理", "Debugging Discipline"; or create a new section if none fits).
- Show the proposed diff as a fenced block with
-/+lines. - Ask: "执行这个修改？(yes/no)"
- On "yes" → apply via
Edit. On anything else → abort, optionally offer to save as project memory instead.
Never skip the diff step. CLAUDE.md is user-authored authoritative config; silent edits erode trust.
Action: Edit Project CLAUDE.md (confirm-first)
Same flow as global, but target is <cwd>/CLAUDE.md (walk up if not at root). Same diff-then-confirm requirement.
Action: Suggest Harness Commands (suggest-only)
Produce the exact string the user should paste, not a description:
context polluted — paste this to fork:
/forkor
approaching capacity — compact first, then continue:
/compactDo not wrap in explanations. The command is the deliverable.
What this skill cannot do (be honest about it)
- Invoke
/fork,/compact,/btw,/clear, new session — harness-only. - Edit another agent's transcript.
- Auto-install hooks — use
/update-configfor that.
If the user asks for one of these, say so and give them the command to paste.
Output convention
Every action that writes a file must echo its absolute + relative path (per project-wide output-paths rule). Applies to memory files, CLAUDE.md edits (show final path), and any derived artifacts.
