Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00053 | $0.00608 |
| Opus 5 | $0.00026 | $0.00304 |
| Sonnet 5 | $0.00011 | $0.00122 |
| Haiku 4.5 | $0.00005 | $0.00061 |
Grade A, and why
threnody-subtasks 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 10d 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
Threnody subtask monitoring
list_subtasks tracks execute_subtask utility delegation only.
Host-native swarms and host_spawn_waves do not appear here — track those
by wave completion in the host shell.
Token-cheap review and swarm changes happen on the host-native wave path, not in
this utility subprocess monitor. Use this skill only after explicit
execute_subtask delegation to utilities.
When to use
- User enabled
providers.delegation_utilities_enabled: true - Work was delegated via
execute_subtaskto OpenCode, Aider, or a local endpoint - Need to pause/resume a running utility subprocess
Process
-
Call
list_subtasks(MCP: Threnody). -
Format Running Active (
active_counttotal):
For each group in active_groups:
Parallel wave (parallel: true):
WAVE: wave-1 (3 running in parallel)
- abc123 [low] gpt-5-mini 12.3s -> config.py
- def456 [low] gpt-5-mini 12.1s -> models.py
Single task:
abc123 [med] claude-sonnet-4.6 4.2s -> main.py
Each row: task_id (first 6 chars), [tier], model or resolving, elapsed seconds, target_file or prompt excerpt (60 chars).
If active_count == 0: No subtasks currently running.
- Format Recently Completed (last 10):
abc123 DONE [low] gpt-5-mini / Aider 28.1s -> config.py
def456 FAILED [low] unknown 31.0s -> models.py
Group consecutive entries with the same wave_id under a WAVE label.

For live monitoring, run `threnody-watch` in another terminal tab.

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.
- 10d ago First seen · 78 lines · 53 tokens per session scan A a6d2fb66f328
threnody-subtasks is a skill published in the GitHub repository timjensgrossinger/threnody (2 stars, last pushed 13d ago), licensed Apache-2.0. It adds 53 tokens to every session and 608 once invoked, about $0.0003 per session on Opus 5. 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 2026-08-31.
Other skills, from other repositories
personetta-set-active
Switches the active Personetta persona via set-active. The target tool is auto-detected from the host agent (Claude Code here), so no --format is needed. Use when the user asks to change recipe, switch persona, or set active role.
personetta-current
Reports the active Personetta recipe id using the installed CLI. The host agent (Claude Code here) is auto-detected. Use when the user asks for their current persona, active recipe, or which Personetta role is on.
personetta-list
Lists Personetta recipes (and optionally roles) using the installed Personetta CLI. Use when the user asks what recipes or personas exist before switching.
rework-rate
Measure and interpret PR rework rate — the emerging 5th DORA metric.
curate-a-team-library
Use when building a managed team skills library for a real stack. Map work to shelves, browse before curating, write meaningful whyHere notes, and create a starter pack once the first pass is solid.
migrate-skills-between-libraries
Use when moving skills between library workspaces or upgrading from a personal library to a team library. Export from one workspace, import into another.
