start-coding-task

start-coding-task is a skill for Claude Code, Codex from edgar-durand/codeagent-mobile-clients. It costs 33 tokens per session (392 once invoked), scanned A, original, MIT.

A procedure for starting a coding task on one of the user's existing CodeAgent sessions. It selects the right session, passes along the task and requirements, and reports where the work started.

In plain words
What is it for?
Use it when the user asks an agent to fix a bug, implement a feature, add tests, or solve an issue in an existing coding session.
Why use it?
It prevents work from being sent to the wrong repository or session when several are available. It also handles offline sessions, specific agents, and agents that use prepaid credits.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

start-coding-task scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Start a coding task

Use this when the user asks to have an agent do coding work ("fix…", "implement…", "add tests for…", "solve issue #…").

Workflow

  1. Call list_sessions. If the user named a repository, project or host, pick the session whose repository or title matches. If none matches, or more than one could, ask the user which session — never guess.
  2. If the chosen session is offline, tell the user the host is offline; start_task will try to wake a codespace or CodeAgent Box, but a local CLI must be started by the user.
  3. If the user asked for a specific agent, call list_agents and pass its id as agent_id. If that agent is managed (uses credits), follow the continue-with-codeagent-credits skill first.
  4. Call start_task with a clear, self-contained task (include the issue number and any acceptance criteria the user gave). For a GitHub issue, describe it in the task text; the agent reads the repository itself.
  5. Reply in three lines: what was started, on which session (title, session_id), and that you will report progress on request. Example:
    Started Claude Code on org/app (session cmt…): "Fix checkout validation".
    Status: running. Ask me "what's the agent doing?" for an update.
    
  6. Never say the work is done. start_task only accepts the task; completion is only visible through get_session (status idle with new changes) or get_diff.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
