post

post is a skill for Claude Code from fprochazka/claude-code-plugins. It costs 33 tokens per session (2,706 once invoked), scanned C, original, MIT.

A workflow for posting an existing code-review report to the current GitLab merge request as inline comments and a summary. GitLab is a platform for hosting code repositories and reviewing proposed changes.

In plain words
What is it for?
Use it after a full review to publish file-and-line findings on the merge request and add the remaining findings and final verdict as a summary comment.
Why use it?
It prevents findings from being invented or re-analysed during posting. It also stops when no review report from the current session is available.

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 C, and why

post scanned grade C with 1 finding 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 15d 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.

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

How it starts

The opening of the file, as written. The whole thing — 195 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Post Code Review to MR

Post the code-review report from this session to the current GitLab merge request as one review: inline diff comments (for findings anchored to specific file/line locations) written as GitLab draft notes, then published together with one summary note (for everything else plus the final verdict). The MR gets one notification, and nobody, human or watcher, sees a half-posted review.

This command only posts. It does not re-run the review and it does not re-analyze the diff. If no review report exists in this session, stop and tell the user to run /code-review:full first.

Phase 1 — Locate the report (in-session only)

The report must already exist in this session's conversation history, produced by an earlier /code-review:full run. Do NOT search the filesystem, do NOT re-derive findings from the diff, do NOT re-launch review agents.

  • If you can see the report in the current session context → proceed.
  • If you cannot → stop immediately and reply with:

    No code-review report found in this session. Run /code-review:full first, then re-run /code-review:post.

Do not invent findings. Use only what the existing report says.

Phase 2 — Load tooling

Before making any GitLab calls, invoke the glab-discussion skill to load its usage guidance for MR diff comments, replies, and standalone discussions.

If the skill is unavailable, stop and tell the user.

Drafts need glab-discussion 0.5.0 or newer. If a glab-discussion call fails with an unknown command or flag, run glab-discussion drafts --help. If that fails too, stop and tell the user to upgrade with uv tool upgrade glab-discussion (0.5.0 or newer).

Phase 3 — Identify the target MR and its pending drafts

You should already know the MR from the /code-review:full context loaded earlier in this session. Use that MR. If the MR is ambiguous or missing, ask the user for the MR URL before posting anything.

Then run glab-discussion read and look for pending drafts: draft-<id>.txt files and [DRAFT] (draft:<id>) blocks inside thread files. GitLab shows a user only their own drafts, and the publish in Phase 7 publishes every one of them, so sort them before you write anything:

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.

post is a skill published in the GitHub repository fprochazka/claude-code-plugins (15 stars, last pushed 7d ago), licensed MIT. It adds 33 tokens to every session and 2,706 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it C with 1 finding (hidden instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-12.
