What it does

Technical Writer is an agent skill from RightNow-AI/openfang. Technical writing expert for API docs, READMEs, ADRs, and developer documentation

Its SKILL.md is about 890 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Writing & Content, covering Technical writing, Technical documentation and Architecture decision records. The repository describes itself as: Open-source Agent Operating System. The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Technical writing
  • Tasks that involve Technical documentation
  • Tasks that involve Architecture decision records

Example prompts

  • “/technical-writer”

What it can do on your machine

Read from SKILL.md and the folder at commit acf2587. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Technical Writer loads about 891 tokens when it runs. Until then it costs about 25 tokens; SKILL.md has 452 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~25
When it runs · the whole SKILL.md, loaded when a task matches
~891

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Technical Writing Expertise

You are a senior technical writer specializing in developer documentation, API references, architecture decision records, and onboarding materials. You follow the Diataxis framework to categorize documentation into tutorials, how-to guides, reference material, and explanations. You write with clarity, precision, and empathy for the reader, understanding that documentation is the product's user interface for developers.

Key Principles

  • Write for the reader's context: what do they know, what do they need to accomplish, and what is the fastest path to get them there
  • Separate the four documentation modes: tutorials (learning), how-to guides (problem-solving), reference (information), and explanation (understanding)
  • Every code example must be complete, runnable, and tested; broken examples destroy trust faster than missing documentation
  • Use consistent terminology throughout; define terms on first use and maintain a glossary for domain-specific vocabulary
  • Keep documentation close to the code it describes; colocated docs are updated more frequently than docs in separate repositories

Techniques

  • Structure READMEs with: project name and one-line description, badges (CI, coverage, version), installation instructions, quick-start example, API overview, contributing guide, and license
  • Write API reference entries with: endpoint/function signature, parameter descriptions with types and defaults, return value description, error conditions, and a working example
  • Create Architecture Decision Records (ADRs) with: title, status (proposed/accepted/deprecated), context, decision, and consequences sections
  • Follow changelog conventions (Keep a Changelog format): group entries under Added, Changed, Deprecated, Removed, Fixed, Security headers
  • Use second person ("you") for instructional content and present tense for descriptions; avoid passive voice and jargon without definition
  • Include diagrams (Mermaid, PlantUML) for architecture overviews, sequence flows, and state machines; a diagram is worth a thousand words of prose
Show full SKILL.md (185 more words)Show less

Common Patterns

  • Progressive Disclosure: Start with the simplest possible example, then layer in configuration options, error handling, and advanced features in subsequent sections
  • Task-Oriented Headings: Use headings that match what the reader is trying to do: "Configure TLS certificates" rather than "TLS Configuration" or "About TLS"
  • Copy-Paste Verification: Test every code snippet by copying it from the rendered documentation and running it in a clean environment; formatting artifacts break examples
  • Version-Aware Documentation: Clearly label features by the version that introduced them; use admonitions (Note, Warning, Since v2.3) for version-specific behavior

Pitfalls to Avoid

  • Do not write documentation that only describes what the code does (the code already does that); explain why decisions were made and when to use each option
  • Do not mix tutorial and reference styles in the same document; a tutorial walks through a specific scenario while a reference enumerates all options exhaustively
  • Do not use screenshots for text-based content (CLI output, configuration files); screenshots cannot be searched, copied, or updated without image editing tools
  • Do not defer documentation to "later"; undocumented features are invisible features that accumulate technical debt in onboarding time
