Manual or hook-triggered context operator. Evaluates the current session for pollution (long conversations, topic drift, stale noise), AND takes concrete context-shaping actions: writing project memory, updating global or project CLAUDE.md (with diff + confirm), and recommending harness commands like /fork, /compact, /btw. Covers the full surface of context-affecting operations Claude can reach — direct file edits are auto-executed or confirmed based on sensitivity; harness-only commands (/fork etc.) are surfaced as one-click suggestions.

Claude Code-oriented instruction skill. Agent home must resolve from `SKILL_AUTO_CONTEXT_AGENT_HOME`, the shared Skill Publisher skills profile, or a one-time user answer; do not assume a fixed runtime directory.
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 global agent instructions, 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 skill-publisher 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 (/lov-auto-context [args])
Two call shapes:
A. Bare call — health report + opportunistic memory write
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
/lov-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 / 加到全局指令"
edit the configured global instructions file
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: <resolved-agent-home>/projects/<project-slug>/memory/.
Resolve <resolved-agent-home> from the User Configuration section before
writing. The memory directory should already exist; do not create a new
runtime layout silently.
Write with the required frontmatter (name, description, type).
For feedback / project types, include **Why:** and
**How to apply:** lines.
Update MEMORY.md with one-line pointer under 150 chars.
Report the absolute + relative path.
Action: Edit Global CLAUDE.md (confirm-first)
Target: <resolved-agent-home>/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:
/fork
or
approaching capacity — compact first, then continue:
/compact
Do 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-config for 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.
User Configuration
Resolve agent paths in this order:
SKILL_AUTO_CONTEXT_AGENT_HOME.
Shared profile ${SKILL_PROFILE_PATH:-$HOME/.skill-publisher/skills/profile.json}
keys: agent.home, claude.home, or runtime.agent_home.
Ask the user once for the agent home directory and use that value for the
current operation.
For alternate runtimes, set SKILL_AUTO_CONTEXT_AGENT_HOME explicitly or
add the relevant profile key.
