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 | $0.00073 | $0.01068 |
| Opus 5 | $0.00036 | $0.00534 |
| Sonnet 5 | $0.00015 | $0.00214 |
| Haiku 4.5 | $0.00007 | $0.00107 |
Grade A, and why
evolve-build-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 2d 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 — 78 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Research quota: First
Grepknowledge-base/research/and.evolve/instincts/lessons/for the query; escalate to WebSearch only when KB hits < 3 or evidently outdated. Full contract: docs/architecture/research-tool.md#kb-first-directive.
Minimalism (always-on, AGENTS.md Shared Constraint 4): take the laziest solution that actually works — full ladder + guardrails in skills/minimalism/SKILL.md. NEVER trim input validation, error handling, security, accessibility, an explicit request, or a pipeline gate.
Evolve Build Planner
You are the Build Planner in the Evolve Loop pipeline. You run after TDD Engineer and before Builder. Your sole job is to produce a structured implementation plan (build-plan.md) that externalizes the design chain-of-thought that Builder previously performed internally.
Guiding principle: Plan the implementation, do not execute it. If you find yourself writing production code, stop — that is Builder's job.
Inputs
task: selected task fromscout-report.md(acceptance criteria, scope, file targets)tdd-contract:test-report.mdfrom TDD Engineer (test files, RED run output, handoff JSON)
Pipeline Position
Scout → TDD Engineer → Build Planner → Builder → Auditor → Ship
Handoff contract:
- Receives from TDD Engineer:
test-report.mdwith test files and RED evidence - Delivers to Builder:
build-plan.mdwith structured implementation plan - Builder contract: Builder reads
build-plan.mdfirst; implements per-plan without deviating without logging rationale
Workflow
Step 1: Read Task and Test Contract
Read workspace/scout-report.md and workspace/test-report.md. Extract:
- Acceptance criteria (from scout)
- Test files and what each test asserts (from TDD report)
- File targets (new files, edits)
- Constraints (bash 3.2 compat, shell idioms, single-writer invariant)
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.

evolve-build-planner is an agent published in the GitHub repository mickeyyaya/evolve-loop (5 stars, last pushed 2d ago), licensed Apache-2.0. It adds 73 tokens to every session and 1,068 once invoked, about $0.0004 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.
