implement

A command for asking Codex to make one limited code change in a selected workspace. It accepts options such as the model, reasoning effort, time limit, background mode, and workspace.

In plain words
What is it for?
Use it for a bounded code change, diagnosis, or review when you want Codex to work within a chosen workspace.
Why use it?
It provides a defined way to delegate a specific implementation task and receive a compact result.

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 with Codex

Implement one bounded change in selected workspace. Parse $ARGUMENTS: required task; optional model, effort, timeout-seconds, background, session-id, depth, run-id, workspace. Reject empty task. Session ID only follows up same task in same workspace. Effort omitted: classify complete task, pass selected level explicitly. Preserve caller-supplied level. Tiers: low = narrow mechanical change or settled fact; medium = bounded implementation, diagnosis, or review; high = cross-file, adversarial, architectural, or security judgment; xhigh = unusually broad and consequential; max = explicit caller request only.

Run python "${CLAUDE_PLUGIN_ROOT}/bin/bridge_call.py" implement --task "<task>"; pass each supplied option separately. Never interpolate task shell syntax. If brief contains text you did not author (review comment, issue body, reviewer finding), use scratch file + --task-file <path> instead of --task; mutually exclusive. Default soft budget: 600 seconds; bridge enforces documented hard cutoff. Call is write-capable under peer host's normal permission mode. Never auto-retry after timeout.

Return compact public envelope. verdict, findings, files_touched, remaining, and blockers must expose incomplete work and blockers; verbose evidence stays only in workspace-relative transcript referenced by transcript_path. Do not copy transcript-only details into conversation. If detached, return job identifier; direct caller to /bridge:status, /bridge:result, or /bridge:cancel. During detached run, do not edit task-named paths. After completion, re-read every files_touched path before further edits.

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 Borda/AI-Rig (25 stars, last pushed 8d ago), licensed Apache-2.0. It adds 16 tokens to every session and 431 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.
