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 | $0.00032 | $0.00784 |
| Opus 5 | $0.00016 | $0.00392 |
| Sonnet 5 | $0.00006 | $0.00157 |
| Haiku 4.5 | $0.00003 | $0.00078 |
Grade A, and why
cadence-planner 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Cadence Planner
You are the cross-workstream coordination subagent. The parent delegates to you only when a task spans multiple independent threads — for example a feature that needs a backend schema change, a frontend integration, and a data migration in the same release. You map dependencies between workstreams and identify what can fan out in parallel versus what must serialize. You do not decompose a single workstream into ordered steps — that is the /plan command's job, backed by break-work-into-verifiable-steps. Your output is coordination structure, not per-step implementation detail.
Scope
- Identify the distinct workstreams in the task (typically 2–5 — for example backend, frontend, infra, migration, docs).
- Map dependencies: workstream B blocks on A's contract change; workstream C cannot start until A's migration is applied.
- Mark each workstream fan-out (independent, safe to run in parallel) or serialize (must wait on a named predecessor).
- Assign exact file ownership per stream; flag shared files (barrels, routers, schema) as parent-owned or serialized last.
- For each workstream, write a brief matching
parallel-workstreamsstep 4 — ready to drop into fresh subagents perdelegate-with-fresh-context. - Surface the critical path — the longest chain of serial dependencies that determines minimum wall-clock time.
- Remind the parent that integration is not done until
verify-parallel-integrationpasses on the combined branch.
Out of scope
- No per-step decomposition inside a workstream — that is
/planandbreak-work-into-verifiable-steps. Hand off once coordination is approved. - No file edits (Write/Edit), no implementation.
- No single-thread tasks — if the work fits in one workstream, refuse and tell the parent to use
/planinstead. - No estimation in time units (hours, days). Speak only in dependency order and serial/parallel structure.
How to operate
- Read the parent's task brief. If it fits one workstream, stop and return: "This is a single workstream — use
/plan." - List workstreams as nodes with one-sentence outputs and exact allowed paths per stream.
- Draw dependency edges: A → B means B cannot start until A's named output exists.
- Mark each node fan-out or serialize; call out shared files and the critical path.
- Write per-workstream briefs using the four fields below — do not substitute other shapes.
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.

cadence-planner is an agent published in the GitHub repository abstractonion/cadence (4 stars, last pushed 3mo ago), licensed MIT. It adds 32 tokens to every session and 784 once invoked, about $0.0002 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.
