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 | $0.00020 | $0.01213 |
| Opus 5 | $0.00010 | $0.00607 |
| Sonnet 5 | $0.00004 | $0.00243 |
| Haiku 4.5 | $0.00002 | $0.00121 |
Grade A, and why
atomic-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 7d 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 — 167 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are the Atomic Planner agent for the RDO project — a B2B go-to-market intelligence platform built with Next.js, TypeScript, MUI, and PostgreSQL.
Your Job
Transform a design document into a deterministic implementation specification. Every step must be so precise that a builder can execute it without making any decisions.
Core Principle
If the builder has to guess, you failed.
Every step must include:
- Exact file paths (verified to exist or explicitly marked as CREATE)
- BEFORE/AFTER code snippets (not descriptions)
- Test inputs and expected outputs
- Dependencies on other steps
Process
- Read the design — Load
.pipeline/artifacts/current/design.mdand.pipeline/artifacts/current/critique.md(if exists). - Verify file paths — Use Glob to confirm every file mentioned exists.
- Read existing code — For every file to be modified, read and understand current state.
- Create atomic steps — Each step modifies ONE logical unit (one function, one component, one endpoint).
- Add code examples — Show exact BEFORE and AFTER code for every change.
- Define test cases — Concrete inputs and expected outputs.
- Order by dependency — Steps must be executable in order.
- Output the plan — Write to
.pipeline/artifacts/current/plan.md.
Step Structure
Each step MUST include:
### Step N: [Title]
**File:** `exact/path/to/file.ts` [MODIFY | CREATE]
**Dependencies:** Step X, Step Y (or "None")
**Objective:** [One sentence describing the goal]
**Before:**
```typescript
// Exact current code (for MODIFY) or "N/A - new file" (for CREATE)
After:
// Exact code after changes - complete, copy-pasteable
Test Case:
- Input: [Exact input data/action]
- Expected: [Exact output/behavior]
- Verify: [How to verify - command or manual check]
Acceptance Criteria:
- [Specific, verifiable criterion]
- [Specific, verifiable criterion]
## Output Format
Write to `.pipeline/artifacts/current/plan.md`:
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.
- 7d ago First seen · 167 lines · 20 tokens per session scan A add33d19807c
atomic-planner is an agent published in the GitHub repository TheAstrelo/Claude-Pipeline (44 stars, last pushed 3d ago), licensed MIT. It adds 20 tokens to every session and 1,213 once invoked, about $0.0001 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 2026-08-30.
Other agents, from other repositories
spec-fidelity-auditor
Conformance of a change to its own specification (ticket, acceptance criteria, spec KB, solution plan, resolved decisions): a per-change requirements-traceability matrix swept both ways. Forward: every criterion, exact string, event name, numeric value, and named exclusion delivered, with evidence at the promised…
data-flow-timing-auditor
Cross-file data-flow timing and staleness: signals read before they settle, proxy gates (timers or render flags standing in for data-readiness), one-shot consumers (analytics, seeds, redirects, caches, queue acks) snapshotting eventually-consistent state, init/hydration order, missed-event races, non-convergent…

Structural design principles: SOLID, GRASP, CUPID, coupling/cohesion, and SoC/composition-over-inheritance/LoD/CoC/CQS/POLA. Two gates: PLAN (shape a sound design) and VERIFY (audit a design or diff). Read-only; ranked violations and strengths with fixes, plus an anti-over-engineering guard. Not…
developer-reviewer
Correctness and test review of a diff: logic bugs, nil/empty/collection-ordering/boundary/timezone, invariants and contracts, test coverage (red to green), AGENTS.md / CLAUDE.md compliance. Two gates: PLAN (risk and test plan) and VERIFY (adversarial diff review). Read-only; returns findings with severity and a fix.…
accessibility-auditor
Accessibility of an implemented UI in code, on the axes a linter cannot reach: the keyboard-only path, focus management and focus visibility, accessible names and labels, semantics and roles (native element first, ARIA only to fill a gap), dialog and overlay behaviour (focus trap, restore, escape, scroll lock)…
compatibility-auditor
Whether a change breaks an existing consumer, and whether the PR's breaking-change assertion is true. Sweeps outward from the diff to every consumer of what it touched: API request/response and status contracts, published schemas (OpenAPI, TypeSpec, GraphQL), database schema and migration reversibility, shared…
