What it does
This skill wipes session data for a context-mode project in one of two scopes: a project-scope purge that deletes the entire knowledge base, every session's database rows, the events markdown file, and all stats, or a session-scope purge that deletes only one named session's rows and search index chunks while leaving sibling sessions and project-wide stats untouched. It always asks the user to decide the scope first, and for a project-scope purge it explicitly warns that everything will be deleted.
The actual deletion runs through one MCP tool call that always requires an explicit confirm flag, with a scoped form that implies session scope from a given session id, and a project form that is the explicit destructive default. Passing a session id together with scope set to project is rejected as a contradiction, and setting scope to session without a session id throws an error rather than silently picking one.
After the call it reports exactly what was deleted, and for a scoped purge confirms that other sessions and project-wide stats were preserved; the skill notes this is the only way to delete this data, that a separate stats command is read-only, and that neither clearing nor compacting the conversation touches any of this stored data.
When your agent uses it
- Wiping one polluted session's indexed data without affecting others
- Starting completely fresh on a project whose knowledge base is stale
- Clearing all context-mode data before switching to an unrelated project
Example prompts
- “Purge just this session's context-mode data, it's polluted.”
- “Wipe the entire project's knowledge base, I'm starting over.”
- “Clear context-mode data before I switch to the other project.”
Requirements
- The context-mode MCP server's ctx_purge tool
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Decide the scope first with the user
- Warn the user about scope:'project'. Everything will be deleted
- Call the mcpcontext-modectx_purge MCP tool with the chosen parameters
- Report the result to the user — the response lists exactly what was deleted and (for scoped purges) confirms that other sessions and…
What it can do on your machine
Read from SKILL.md and the folder at commit 0dfbe8d. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Context Mode Knowledge Purge loads about 671 tokens when it runs. Until then it costs about 47 tokens; SKILL.md has 316 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.
Safety
Auto-check passed
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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 316 words (~671 tokens).
“Permanently deletes session data for this project. Two scopes are supported (issue #520):”
- name
- ctx-purge
- user-invocable
- true
