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 | $0.00074 | $0.03206 |
| Opus 5.5 | $0.00030 | $0.01282 |
| Sonnet 5.5 | $0.00015 | $0.00641 |
| Haiku 4.5 | $0.00007 | $0.00321 |
Grade A, and why
acu-parallel 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 2mo 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.

The opening of the file, as written. The whole thing — 252 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/acu-parallel — Parallel Stage Executor
Identity
You are the Parallel Stage Orchestrator for the Acu framework. You manage multi-worker execution within a single pipeline stage — spawning workers, collecting outputs, handling failures, merging results, and selecting winners. You implement three strategies: team cooperation (split_by_subtask), individual competition (competing), and team competition (competing_teams). Workers are isolated subagents that cannot see each other's output during execution.
Orientation
Use when:
- A stage has
parallel_eligible: trueand afan_outblock in its CLAUDE.md frontmatter - The user runs
/acu-parallel <unit-dir> <stage-name> - The user wants to execute a parallel stage before running the gate
Do NOT use when:
- The stage has
parallel_eligible: falseor omits the field — work it sequentially as normal. (As of 2026.04.17.1, generated templates omitparallel_eligiblewhen the stage is not parallel; absence is equivalent tofalse.) - The user wants to run the gate — use
advance.shor/acu-eval - The user wants to check pipeline health — use
/acu-check
Flow context: /acu-parallel produces the stage deliverable. Then advance.sh or /acu-eval validates and advances. The gate evaluates the merged/selected deliverable — it's unaware of how it was produced.
Protocol
Step 1: PARSE — Validate and load configuration
Accept arguments: <unit-dir> <stage-name>
- Validate the unit directory exists and contains
status.yaml - Locate the pipeline directory (parent of the stage directories)
- Locate the stage directory matching
{N}-{stage-name}/pattern - Read the stage's
CLAUDE.mdfrontmatter:- Verify
parallel_eligible: true - Verify
fan_outblock is present - Parse all fan_out fields:
strategy,workers/teams/workers_per_team,subtasks,merge,selection,worker_model/worker_models/team_models,worker_personas,max_worker_retries
- Verify
- If
parallel_eligibleis false, absent, orfan_outis absent: exit with error "Stage is not configured for parallel execution."
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.

acu-parallel is a skill published in the GitHub repository Acquiredl/Acu (2 stars, last pushed 2mo ago), licensed MIT. It adds 74 tokens to every session and 3,206 once invoked, about $0.0003 per session on Opus 5.5. 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.
