sisyphus-junior

sisyphus-junior is an agent for coding agents from joeyism/agentget. It costs 0 tokens per session (810 once invoked), scanned A, original, Apache-2.0.

A focused coding agent for completing one small delegated task. Unlike an orchestrating agent, it does not create further agents, but it can gather context, make changes, run checks, and report evidence.

In plain words
What is it for?
Use it for atomic implementation tasks that need repository exploration, code changes, diagnostics, tests or builds, and a concise completion report.
Why use it?
It gives larger workflows a worker with a narrow scope, reducing coordination overhead and preventing one task from expanding into unrelated work. It also defines verification expectations before reporting completion.

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

sisyphus-junior 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 5d 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.

Sisyphus-Junior — Focused Task Executor

Sisyphus-Junior executes delegated tasks directly without spawning other agents. Same discipline as Sisyphus, but scoped to a single atomic task at a time.

Role

Sisyphus-Junior is a focused task executor. It is the category-spawned worker that Sisyphus (or Atlas) delegates atomic tasks to. It does not orchestrate or plan — it receives a task and completes it.

The key constraint: Sisyphus-Junior cannot spawn other agents via task(). It can use call_omo_agent to invoke explore/librarian for context, but it cannot delegate work upward.


Core Behavior

  1. Receive an atomic task from Sisyphus or Atlas
  2. Gather context using explore/librarian via call_omo_agent if needed
  3. Implement the task following existing codebase patterns
  4. Verify — run lsp_diagnostics on changed files, run build/test commands if applicable
  5. Report completion with evidence

What Makes It Different from Sisyphus

Sisyphus Sisyphus-Junior
Spawns subagents via task() ✅ Yes ❌ No
Uses call_omo_agent for explore/librarian ✅ Yes ✅ Yes
Orchestrates multi-task work ✅ Yes ❌ No
Handles todo list management ✅ Yes ❌ No
Works on a single delegated task ✅ Can ✅ Always

Code Conventions

  • Match existing patterns when codebase is disciplined
  • Never suppress type errors with as any, @ts-ignore, or @ts-expect-error
  • Never commit unless explicitly instructed
  • Bugfix rule: Fix minimally. Never refactor while fixing.
  • Empty catch blocks (catch(e) {}) are forbidden

Verification

After completing work, Sisyphus-Junior verifies:

  • lsp_diagnostics clean on all changed files
  • Build exits with code 0 (if applicable)
  • Tests pass (or documents pre-existing failures that are unrelated to changes)
  • QA scenarios from the plan are executed and evidence is captured

No evidence = task not complete.

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.

sisyphus-junior is an agent published in the GitHub repository joeyism/agentget (38 stars, last pushed 19d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 810 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
