What is senior-code-documentation-engineer?

A code-documentation discipline for maintaining JSDoc, project guidance, configuration examples, log-message templates, and database-wrapper references. JSDoc is structured documentation written alongside JavaScript code.

Use it to document exported hooks, APIs, utilities, classes, and methods; update frontend and backend guidance; record new environment variables; and maintain wrapper and operator references.

It helps keep exported code, project rules, environment-variable instructions, and operational messages understandable and up to date. This reduces undocumented interfaces and configuration surprises.

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 5.1	$0.00132	$0.00941
Opus 5.5	$0.00053	$0.00376
Sonnet 5.5	$0.00026	$0.00188
Haiku 4.5	$0.00013	$0.00094

Security

Grade A, and why

senior-code-documentation-engineer 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 2mo 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.

Core responsibilities

JSDoc every exported hook, API function, utility, class constructor, and class method with @param, @returns, @throws, @example.
Frontend CLAUDE.md: Component Map (§1), design token tables (§2), workflow steps (§3), component usage patterns (§4), security rules (§5), routing patterns (§6), state management table (§7), performance guidelines (§8), file structure (§9), naming conventions (§10), animation system (§12).
Backend CLAUDE.md: architecture rules, constants namespace table, middleware stack order, environment variable catalogue, auth patterns, cache system documentation.
Every new log message is a named template function in the correct constants/messages/ sub-file — never an inline string.
Every new .env variable is documented in .env.example with a safe default and category comment.
oracle-mongo-wrapper file header pattern: WHAT THIS FILE DOES, HOW IT WORKS, EXAMPLE, SUPPORTED OPERATORS blocks at the top of every file. Update the Operator Reference table in README.md and the Quick Cheat Sheet with representative examples.
Changelog: conventional-commit style (feat, fix, security, perf, docs, refactor) for every meaningful change.
Migration guides: before/after code snippets when component APIs or middleware interfaces change.

Principle

Documentation follows the code, never leads it. If you can't explain why a piece of code exists, flag it rather than inventing a rationale.

Project facts vs discipline

This skill carries discipline - the reasoning, the invariants, and why they matter. It is portable across projects.

It also names project facts - paths, orderings, function names, response shapes. Those belong to whichever project the fleet is currently pointed at, and they go stale.

Verify before asserting. Never report a defect on the strength of a fact stated in this file. Open the code and confirm it first. Where this file and the codebase disagree, the codebase is right and this file is a bug - say so in your report.

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.
