Based on SOC occupation classification
Run the background harden pass for one artifact -- crystallize, update, or heal a skill, a service, or the system interface in an isolated worktree, then report back. Invoke when your task file hands you an artifact to harden; it names the operation and artifact to compose.
Promote the just-finished work into a new, reusable, committed, tested skill. Use when that process would recur with new inputs -- especially something you figured out through research or debugging -- or when the user says 'crystallize this'.
Fetch data from somewhere (an external service, an API, a third-party source), process it, and show it to the user -- the "go get all this stuff, do something to it, and put it in front of me" task. Use when the ask is to retrieve real data, transform/summarize/classify it, and surface the result. Validates auth first, confirms a real sample covering every data shape, then crystallizes the pipeline in the background while building surfaces.
Use when writing or reasoning about code that calls Claude -- an AI-driven service, an AI integration, or a skill's scripted model step. Covers the three scenarios (one-shot completion, one-shot agentic task, full agent) and the cost / credentialing model.
Fix an existing artifact that errored or delivered a wrong result. This applies to skills or web services. Invoke at turn-end, after you worked around the failure to satisfy the user's request.
Create a sub-agent to perform a larger task. Use when work is large enough to warrant a separate context, involves multi-file changes, or benefits from isolation.

Use this skill when the user asks you to work with files located directly on their computer.
latchkey curl calls to communicate with the remote WebDAV server. (They are the same as normal curl calls, just going through the Latchkey Gateway.)latchkey curl -XPOST http://latchkey-self.invalid/permission-requests when the curl request comes back with the "request not permitted by the user" message. See the "Ask for user permission" example below.The base URL is http://latchkey-self.invalid/minds-api-proxy/api/v1/files. Only the user's home directory and the user's system temp directory are accessible. MOVE and COPY operations are not supported.
latchkey curl -O http://latchkey-self.invalid/minds-api-proxy/api/v1/files/home/hynek/project/notes.txt
latchkey curl -T localfile.txt http://latchkey-self.invalid/minds-api-proxy/api/v1/files/home/hynek/project/remotefile.txt
latchkey curl -s -X PROPFIND -H "Depth: 1" http://latchkey-self.invalid/minds-api-proxy/api/v1/files/home/hynek/project/ | xmlstarlet sel -N d=DAV: -t -m "//d:response/d:href" -v . -n
When a request comes back with the "request not permitted by the user" message, ask the user for permission first:
# 1. Retrieve the list of your existing permissions if necessary.
latchkey curl http://latchkey-self.invalid/permissions/self | jq .rules
# 2. Ask for the necessary missing permissions.
# (Never pipe the output through jq because frontend rendering depends on seeing the full output from your tool.)
latchkey curl -XPOST http://latchkey-self.invalid/permission-requests \
-H 'Content-Type: application/json' \
-d '{"agent_id": "'"$MNGR_AGENT_ID"'", "type": "file-sharing", "payload": {"path": "/home/hynek/project", "access": "READ"}, "rationale": "I'"'"'d like to access the /home/hynek/project directory in order to find the most recent accounting spreadsheet you asked me about."}'
The body must be a JSON object with exactly four fields:
agent_id (use $MNGR_AGENT_ID), rationale, type (use "file-sharing"), and payload.
payload must be an object with exactly two string fields: path and access. path should be absolute, access must be "READ" or "WRITE".
If you don't know the absolute path to the user's home directory, you can use "~" in your permission request. The backend will expand it to the full path, which you can use to work with the files once your request is approved.
After posting, wait for a message indicating whether the user approved or denied the permission request.
