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 | $0.00069 | $0.01394 |
| Opus 5 | $0.00034 | $0.00697 |
| Sonnet 5 | $0.00014 | $0.00279 |
| Haiku 4.5 | $0.00007 | $0.00139 |
Grade A, and why
develop-like-linear 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 yesterday.
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 — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Core principle
Create momentum, don't sprint — find a cadence and stick to it; the goal is healthy, sustained momentum across cycles, not a rush to a deadline [Method: introduction]. Paired with a bias for small scope: "ship early... simplify and ship smaller" is principle #1 of how the company says it thinks and works [careers].
Principles
- Momentum, not sprints — pick a cadence and hold it [Method: introduction]
- Ship early, ship smaller — simplify scope before building [careers]
- Rotating project leads — ownership is real but not permanent; everyone learns the role [how we run projects]
- Write concise specs (1-2 pages) before building, not after [how we run projects]
- Candidate projects as the continuous unit of planning — triage as ideas arrive, don't wait for a planning ritual [continuous planning]
- Quality is a weekly habit, not a milestone gate — one small fix per engineer per week, every week [Quality Wednesdays]
- Avoid side quests — don't fix every problem, don't add process or documents you don't need [careers]
- Think in principles, not playbooks [careers]
- Keep the team small, do more with less; wear multiple hats [careers]
Workflow
Execute these checkpoints before and during the task. Treat them as required actions, not background description:
What ships with it
4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
- yesterday First seen · 89 lines · 69 tokens per session scan A 256e68399a78
develop-like-linear is a skill published in the GitHub repository marcusrbrown/dev-like (2 stars, last pushed yesterday), licensed MIT. It adds 69 tokens to every session and 1,394 once invoked, about $0.0003 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.
