What is codeatlas-implement?

A workflow for implementing a CodeAtlas code change from discovery through testing and review. CodeAtlas is a code-navigation system that helps locate relevant features and entities in a codebase.

Use it to trace a feature, read its related code and tests, implement a change, run the project's checks, and review the final diff.

It provides a repeatable path for finding the right files, making a small change, and checking that existing behavior still works.

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	$0.00794
Opus 5	$0.00009	$0.00397
Sonnet 5	$0.00003	$0.00159
Haiku 4.5	$0.00002	$0.00079

Security

Grade A, and why

codeatlas-implement 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 48 lines — stays where its author put it; the contents beside it link to each section on GitHub.

CodeAtlas Implementation

Run git status --short.
Identify feature entry points with CodeAtlas MCP trace_feature_flow or search_entities when available.
Read related source, dependencies, and tests.
Choose the smallest change that satisfies the request.
Keep HTTP/MCP code in src/presentation, business logic in src/services, and persistence in src/database or repositories.
Use SQLite + sqlite-vec as default behavior. Do not make PostgreSQL required for local work.
Add regression coverage for changed behavior.
Run:
```
pnpm run build
pnpm test
```
Review git diff --check and final diff.
Call sync_system_memory with a concise change description.

Do not reset, clean, stash, commit, push, or alter unrelated files. Report any unavailable or failing check.

Pipeline verification gates (CI parity)

Features and refactors now ship through a strict CI pipeline. Match these gates locally before finishing so CI stays green:

Root gates: pnpm run typecheck, pnpm run build, pnpm test (Node built-in test runner).
Dashboard gates: cd dashboard && pnpm run typecheck, pnpm run build, pnpm test (vitest).
Dashboard TypeScript is strict: true with noFallthroughCasesInSwitch. Unused-symbol checks (noUnusedLocals/noUnusedParameters) are intentionally off because pre-existing unused locals are widespread; do not re-enable them unless you also clean up every affected component.
Dashboard tests require jsdom 29 and undici@^7 (pnpm-workspace.yaml override is undici: ^7.25.0). Never pin undici below 7; jsdom 29 imports undici/lib/handler/wrap-handler.js, which does not exist in undici 6.
CI security job runs pnpm audit --prod --audit-level=high and gitleaks with no continue-on-error. Never put key-shaped strings in tests or fixtures (e.g. ca_test_key_12345 was caught by gitleaks); use innocuous placeholders like test-token.
CI jobs: build (root + dashboard typecheck/build/tests), sqlite (CODEATLAS_DB_TYPE=sqlite, CODEATLAS_SQLITE_PATH under the workspace), security (audit + gitleaks). Workflow has concurrency cancellation and least-privilege permissions.

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.

codeatlas-implement is a skill published in the GitHub repository giauphan/codeatlas-platform (11 stars, last pushed 3d ago), licensed MIT. It adds 17 tokens to every session and 794 once invoked, about $0.0001 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 2026-08-30.
