implement

A set of implementation rules for building code after an approach has been approved. It covers where code belongs, typing, error handling, secrets, reusable models, and the separation between core logic and external tools.

In plain words
What is it for?
Use it after planning to write the approved code, handle external calls safely, keep core logic independent of MCP, and perform a final quality check before testing.
Why use it?
It keeps implementation aligned with the agreed design and project conventions, while stopping work when the plan is incomplete instead of silently expanding the task.

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.

Security

Grade A, and why

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.

What it actually says

implement

Build the code for the approach approved in /plan-first. If no approach has been validated yet, STOP and run /plan-first first.

Before writing

  • Re-read the relevant parts of docs/ARCHITECTURE.md (where code goes) and docs/CODING_PRACTICES.md (how code is written).
  • Confirm the target files match the approved plan.

While writing

Follow CODING_PRACTICES.md strictly:

  • Full type hints on every function.
  • Keep core/ free of MCP imports — pure logic only.
  • Secrets only through config.py; never hardcode keys.
  • Specific error handling on external calls; add retry/backoff in clients/.
  • Reuse existing models in core/models.py; add to them rather than duplicating.
  • Keep MCP tool functions thin: validate → call core/ → format output.
  • Match surrounding style. No dead code, no leftover debug prints.

Scope discipline

  • Build only what the approved approach covered. If you discover the plan was wrong or incomplete, STOP and go back to /plan-first — don't silently expand scope.

Self-check before handing off

  • Code matches the approved approach
  • Fully typed; would pass ruff and mypy
  • No secrets, no bare except, no dead code
  • core/ has no MCP imports
  • New logic lives in the layer ARCHITECTURE.md assigns it to

Handoff

Once the code is written → hand off to /test to add and run tests. Do NOT commit yet.

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.

implement is a skill published in the GitHub repository justomsharma/github-resume-assistant (0 stars, last pushed 1mo ago), licensed MIT. It adds 60 tokens to every session and 419 once invoked, about $0.0003 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 2026-08-31.
