update-agent skill

L0: One-Sentence Summary

Safely modify an Agent's config, persona, rules, and skills through natural-language conversation.

L1: Overview and Use Cases

Capability Description

update-agent is a Meta-Skill that lets users modify various Agent configurations through conversation. All modifications produce reviewable diff patches that are applied only after user confirmation, with rollback support.

Use Cases

• The user wants to adjust the Agent's communication style ("speak more formally")
• Add new behavioral rules ("from now on, warn me before discussing sensitive topics")
• Install or uninstall skill packages ("learn how to write contracts")
• Batch-update multiple settings ("upgrade all your capabilities")

Core Value

• Safe and controllable: All changes require user confirmation, with rollback support
• Transparent and visible: Changes are presented as diffs, clear and obvious
• Version management: Versions are managed via Git, with traceable history

L2: Detailed Specification

Supported Update Types

Update Type	Target File	Risk Level	Example
Persona update	persona.md	Medium	Modify communication style, values
Principles update	principles.md	High	Add/modify behavioral rules
Skills install	skills/	Medium	Add new skill package
Skills uninstall	skills/	Low	Remove skill package
Memory update	memory/	Low	Add knowledge entry
Tools config	tools/	High	Modify tool permissions

Stage 1: Intent Recognition

Trigger conditions (any one is sufficient):

• The user says "modify your...", "update your...", "adjust the..."
• The user says "from now on you should...", "remember this rule..."
• The user says "install/uninstall this skill..."
• The user describes dissatisfaction with current behavior and expects a change

Output: Identify the update type and target scope.

Stage 2: Change Analysis

Analysis dimensions:

Dimension	Description
Scope of impact	Which files and behaviors are affected
Risk level	Low/Medium/High (see risk classification)
Dependency check	Whether other configs are affected
Conflict detection	Whether it conflicts with existing rules

Risk classification table:

Risk Level	Conditions	Confirmation Requirement
Low	Affects only non-core config (e.g. memory entry)	Simple confirmation
Medium	Affects persona or normal principles	Show diff, then confirm
High	Affects core principles or tool permissions	Detailed explanation + diff + confirm
Protected	Touches a protected path	Block; requires owner permission

Stage 3: Diff Generation

Diff format example:

# persona.md

## 沟通风格

- 友好、随和、轻松幽默
+ 专业、严谨、适度幽默

## 决策偏好

  保持不变...

Diff metadata:

diff_metadata:
  files_affected: 1
  lines_added: 1
  lines_removed: 1
  risk_level: medium
  reversible: true
  estimated_impact: '沟通风格会变得更正式'

Stage 4: User Confirmation

Confirmation interface:

变更预览

影响文件: persona.md
风险等级: 中
影响说明: 沟通风格会从"友好随和"变为"专业严谨"

--- 变更内容 ---
[展示 diff]
----------------

请确认是否应用此变更？
[应用] [取消] [修改]

Confirmation options:

• Apply: Execute the change
• Cancel: Discard the change
• Modify: Enter edit mode for fine-tuning

Stage 5: Apply Changes

Apply the change by reading and writing files directly through AgentFS. Do not call HTTP APIs, and do not operate Git directly (version management is handled automatically by the backend).

AgentFS root directory: ${DESIRECORE_ROOT}/agents/<agentId>/

Read file: Use the cat command to read the current contents of the target file.

Write file: Use a text-editing tool to write directly to the target file. After writing, re-read the file to verify the contents are correct.

Note: After writing the file directly, the backend file watcher automatically detects the change and triggers a Git commit; no manual git command is required.

Stage 6: Receipt Generation

After a successful change, present a user-friendly receipt (do not expose internal paths or technical details):

Updated the communication style of "Legal Advisor Assistant".

Change summary: Communication style adjusted from "friendly and casual" to "professional and rigorous"

If you're not satisfied, you can say "undo the previous change" anytime to roll back.

Special Operation: Version Rollback

Trigger conditions: The user says "undo the previous change", "roll back to the previous version", "restore the original settings"

Rollback flow:

1. Run git log --oneline -10 in the Agent directory to view recent version history
2. Use git show <commit>:<file> to fetch the file contents of the target version, and present them to the user for confirmation
3. After user confirmation, write the target version's contents to the corresponding file
4. Show the change diff and confirm rollback success

# 查看版本历史
cd ${DESIRECORE_ROOT}/agents/<agentId>
git log --oneline -10

# 查看某个版本的文件内容
git show <commit>:persona.md

Background Knowledge

AgentFS repository structure and protected paths are detailed in _agentfs-background.md and _protected-paths.yaml.

Update operation reference table:

User Intent	Target File	AgentFS Path
Modify personality/style	persona.md	${DESIRECORE_ROOT}/agents/<agentId>/persona.md
Modify behavioral rules	principles.md	${DESIRECORE_ROOT}/agents/<agentId>/principles.md
Install/uninstall skills	skills/	${DESIRECORE_ROOT}/agents/<agentId>/skills/
Modify tools config	tools/	${DESIRECORE_ROOT}/agents/<agentId>/tools/
Add memory	memory/	${DESIRECORE_ROOT}/agents/<agentId>/memory/
Modify runtime config	agent.json	${DESIRECORE_ROOT}/agents/<agentId>/agent.json

Error Handling

Error Scenario	Handling
Attempt to modify a protected path	Block the operation; prompt that owner permission is required
File does not exist	The Agent or target file does not exist; ask user to check
Insufficient permission	Filesystem permission error; ask user to check directory permissions
Rollback target version not found	List available versions and ask the user to reselect

Permission Requirements

Operation	Required Role
Update persona	owner, member
Update principles (normal rules)	owner, member
Update principles (safety red lines)	owner
Install/uninstall skills	owner, member
Modify tools permissions	owner
Version rollback	owner
