## AGENTS.md

AGENTS.md solves a very concrete problem: AI coding agents need operational context — how to install dependencies, run the dev server, execute tests, and respect project conventions — but stuffing all of that into a README makes the README worse for human contributors. AGENTS.md gives that guidance its own dedicated file, written in plain Markdown with no required schema, so agents find it reliably while READMEs stay short and human-friendly.

Because it is just Markdown, there is nothing to install and no proprietary tooling to adopt. You add an AGENTS.md at the repository root, list the sections that matter for your project, and agents that support the convention read it automatically. In large monorepos you can place additional AGENTS.md files inside subpackages; agents read the nearest file in the directory tree, so the closest one wins and each package can ship tailored instructions.

The format emerged from collaboration across the AI developer ecosystem — including OpenAI Codex, Amp, Google's Jules, Cursor and Factory — and is now stewarded by the Agentic AI Foundation under the Linux Foundation. It is used by over 60,000 open-source projects and supported by a long list of agents including Codex, Jules, Aider, goose, opencode, Zed, Warp, VS Code, Devin, Amp, Cursor, RooCode, Gemini CLI, Kilo Code and GitHub Copilot.

**Pricing & Plans:** AGENTS.md is completely free and open. There is no paid tier, no account and no commercial product attached to the format.

- **Plain Markdown, no schema:** There are no required fields or special syntax. Use any headings you like and the agent parses the text you provide.
- **Cross-agent compatibility:** One AGENTS.md works across dozens of coding agents such as Codex, Cursor, Jules, Aider, Gemini CLI, Zed and Copilot.
- **Nested files for monorepos:** Drop extra AGENTS.md files into subpackages; agents read the nearest file in the directory tree, so local instructions take precedence.
- **Separation from README:** Keeps human-facing READMEs concise while giving agents the build, test and convention details they actually need.
- **Community-governed open format:** Stewarded by the Agentic AI Foundation under the Linux Foundation, with no vendor lock-in.

**Strengths:** Zero setup: it is just a Markdown file, no SDK or account needed; Works consistently across a large and growing set of coding agents; Nested support makes it practical for large monorepos; Governed by a neutral foundation, so no single vendor controls it

**Limitations:** Agents vary in how fully they honor the instructions they read; Without discipline it can drift out of date like any documentation; No formal schema means structure differs substantially between projects

## Hackmamba

Hackmamba is a developer marketing agency that works with infrastructure, API, and developer-tool companies. Its premise is that developer adoption follows a specific funnel — qualified attention, self-service conviction, rapid adoption, organic advocacy, and compounding efficiency — and that most companies lose developers somewhere in the middle because either the content lacks technical depth or the documentation cannot carry someone to a working integration. Its Developer Adoption Architecture maps those five stages to six disciplines so a programme can be planned end to end.

The six disciplines are strategy and leadership, technical content marketing, technical documentation, developer relations, paid media, and tech influencer marketing. In practice that means technical tutorials and guides, GEO-aware SEO, getting-started flows and API references (Mintlify documentation is a named service), community and hackathon programmes, DX audits, and paid campaigns aimed at developer activation rather than generic reach. The agency positions itself as an embedded extension of client teams rather than an outside vendor.

Hackmamba publishes concrete results rather than vague claims: 49,139 organic clicks in three months for OpenRouter across 39 technical articles, a 46% increase in lead-to-SQL submission rate for Lumana, a 50% reduction in integration time for Celo after a documentation restructure, and a programme that helped Actian's VectorAI DB reach over 1M developers. It reports publishing 1,700+ pieces and influencing more than $400M in pipeline, with clients including Cloudinary, Auth0, appwrite, Netlify, and Sourcegraph.

**Pricing & Plans:** Pricing is not published. Engagements are scoped after a discovery call, with rates quoted per programme based on content volume, channels, and duration. A free planning playbook is offered as a starting point.

- **Technical content marketing:** Tutorials, guides, thought leadership, video content, and GEO-friendly SEO that meet developers at the moment they are searching for a solution.
- **Documentation and onboarding:** Getting started flows, API references, restructures, and Mintlify builds designed to shorten time-to-first-working-build and cut support tickets.
- **Developer relations and DevRel:** Programmes spanning developer community, education, champions, hackathons, and DX audits to drive real adoption rather than raw signups.
- **Paid media for developer audiences:** Paid campaigns and PPC built around developer activation, wired to the same journeys as the organic content.
- **Developer Adoption Architecture:** A five-stage framework that ties discovery, evaluation, integration, advocacy, and compounding efficiency into one governed programme.

**Strengths:** Narrowly specialised in developer audiences rather than general B2B marketing; Covers the full funnel instead of just content or just paid; Documentation capability, including Mintlify builds and full restructures; Named clients and published performance numbers rather than generic claims

**Limitations:** Pricing is quoted per engagement, so costs are not transparent up front; Best value for companies already investing seriously in developer growth, not tiny teams; Agency engagements require internal time for briefs, reviews, and product access; Results depend heavily on how much product documentation and access you can give them
