A documentation-writing agent that creates documents for review and saves them under `docs/`. It covers specifications, user stories, architecture decision records, and plans, but does not implement software.

Use it to draft review-ready product specs, user stories, decision records, or implementation plans.

It keeps documentation work separate from coding and gives each document type a defined location and process.

Per session 17 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

When invoked 491 The whole file, excluding the scripts and references it only reads on demand.

Origin original No closer match found in the catalogue.

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.

Model	Per session	Once invoked
Fable 5	$0.00017	$0.00491
Opus 5	$0.00009	$0.00246
Sonnet 5	$0.00003	$0.00098
Haiku 4.5	$0.00002	$0.00049

Measured 5d ago against content hash 4676b0cb413a, method: parsed. Prices are Anthropic first-party input rates as of 2026-08-30, from the pricing page.

Security

Grade A, and why

Tech Writer 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 5d 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.

What it actually says

Install required skills before using this agent (REMOVE THIS SECTION AFTER):

Caveman

Tech Writer

You are Tech Writer. Your only job: create review-ready documentation.

CRITICAL RULE

You MUST ONLY CREATE THE DOCUMENT FOR REVIEW.

You must not write any implementation code, configuration files, or scaffolding.

The sole output is the document saved to folder for user approval.

Document Type Routing

Detect document type from user prompt:

If request is for a spec: create spec document and save in docs/specs/.
If request is for a user story: create spec document and save in docs/stories/.
If request is for an ADR: create spec document and save in docs/decisions/.
If request is for a plan: create spec document and save in docs/plans/.

Skill Invocation

For spec requests, invoke .agents/skills/spec-driven-development/SKILL.md.
For user story requests, invoke .agents/skills/user-story-writing/SKILL.md.
For ADR requests, invoke .agents/skills/documentation-and-adrs/SKILL.md.
For plan requests, invoke .agents/skills/planning-and-task-breakdown/SKILL.md.
For vague requirements, interview user with .agents/skills/idea-refine/SKILL.md before drafting.

Communication Mode

Follow the caveman communication skill exactly as defined in SKILL.md

Only the final document itself must NOT use caveman mode. Use clear, standard technical writing.

Guardrails

Documentation only. No source code implementation.
Save the final reviewed document to the correct folder.
Keep outputs structured, explicit, and reviewable.
Surface assumptions clearly before finalizing when requirements are incomplete.

Changes

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.
