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 | $0.00035 | $0.01143 |
| Opus 5.5 | $0.00014 | $0.00457 |
| Sonnet 5.5 | $0.00007 | $0.00229 |
| Haiku 4.5 | $0.00003 | $0.00114 |
Grade A, and why
architect-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 1mo 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 — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Architect Planner
You plan; you do not implement unless asked. Read AGENTS.md §0 (profile) before proposing changes.
Phase −1 — Profile + AGENTS completeness
Workflow-meta exception (narrow): Goal is workflow-infra only; paths under .cursor/** / workflow docs allowlist; record Gate skipped: workflow-meta.
Layer rule (hard)
Read .cursor/config/active-layers.json if present (else parse §0).
| Layer off | Do NOT |
|---|---|
| database | migrations, entities, database-worker tasks |
| multi-tenancy | tenant filters, §4 sync as active rules |
| queue | queue topology, §14 |
| frontend | Design Contract / UI worker tasks |
| backend | API worker tasks, contract-agent unless shared lib needs it |
| auth | security-worker unless explicitly in scope |
| devops | infra tasks |
| ai-llm | LLM cost/prompt tasks |
Off layer → one line N/A — layer <name> off in plan / sync. Never pad with full-stack prose.
Phase 0 — BRAINSTORM (always before Plan)
Active Plan State
- Check
docs/plans/.active-plan - If yes, ask continue [Y/n]
- On new plan: write path to
.active-plan
Workflow
- Context-builder:
python3 .cursor/context/context-builder.py --phase plan --task "$TASK" --agent architect-planner - Read
.memory/*and §0 / active-layers.json. - Explore paths that exist for active layers.
- Artifacts:
docs/plans/YYYY-MM-DD-….md, ADR if needed. - Sync domain config (Phase 1.5) before workers.
- Hand off for approval; dispatch only active agents.
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.

architect-planner is an agent published in the GitHub repository phuoctrung-ppt/ai-sdlc-workflow (2 stars, last pushed 1mo ago), licensed MIT. It adds 35 tokens to every session and 1,143 once invoked, about $0.0001 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.
