pipeline-models

pipeline-models is a cursor rule for Cursor from robertsfeir/atelier-pipeline. It costs 2,189 tokens per session, scanned A, original, Apache-2.0.

Rules for choosing an AI model and reasoning effort based on the kind of task an agent must perform.

In plain words
What is it for?
Use them when assigning models and effort settings to agents working on mechanical, routine, or more involved tasks.
Why use it?
They replace personal guesswork with a fixed four-level system and defined signals for increasing effort.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

pipeline-models 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 9d 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.

Pipeline Model Selection (Mechanical -- Eva Does Not Choose)

Loads automatically when Eva reads {pipeline_state_dir}/ files. Model and effort assignment follows a 4-tier task-class model: the agent's task class determines the base model + effort pair, and a small set of promotion signals adjust effort by exactly one rung. Eva sets both parameters explicitly in every Agent tool invocation by looking up the tables below. There is no discretion, no judgment call, no "this one feels complex enough for Opus." The tables are the rule.

Each agent's persona frontmatter also declares its base model and effort so the runtime has a sane fallback. The tables below remain the authoritative source for Eva's invocation-time selection.

Model follows task class, not agent identity. A single agent can occupy different task classes on different runs. Pipeline sizing is a tier-picker signal only; it does not set the model.

Four-Tier Task-Class Model

Tier Task class Model Base effort Typical agents Effort adjustment signal
Tier 1 Mechanical -- no reasoning Sonnet / Haiku low Ellis, scout (haiku), Distillator -- (stays low)
Tier 2 Supporting reasoning -- review / acceptance / compliance / synthesis Sonnet / Opus medium Robert (acceptance), Sable (acceptance), Sentinel, Agatha, Synthesis, Colby (rework), Colby (first-build Small) Read-only / mechanical -- -1 rung (floor low)
Tier 3 Critical-path reasoning -- creates / verifies shipped artifact Opus high / medium Colby (first-build Medium+), Poirot, Darwin (no further promotion -- high is ceiling)
Tier 4 Architectural design Opus high Sarah (already at ceiling; high is the ceiling value)

Adaptive-Thinking Rationale

Per Anthropic's Opus 4.7 guidance, effort controls a model's propensity to think adaptively, not a fixed thinking budget. Fixed thinking budgets are unsupported in Opus 4.7. At medium, adaptive-thinking capacity is bounded even when the model wants to reach for more -- appropriate for coverage-oriented review where over-reading inflates false positives (Poirot standard review). At high, full adaptive thinking is available -- appropriate for execution with branching sub-decisions (Colby first-build, Poirot standard review). max is evaluation-only: prone to overthinking and degraded production output. Ceiling stays high. xhigh and max are forbidden on production workloads -- both cause excessive context burn without quality gain.

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.

pipeline-models is a cursor rule published in the GitHub repository robertsfeir/atelier-pipeline (25 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 2,189 tokens to every session, about $0.0109 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.
