Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00057 | $0.02198 |
| Opus 5 | $0.00028 | $0.01099 |
| Sonnet 5 | $0.00011 | $0.00440 |
| Haiku 4.5 | $0.00006 | $0.00220 |
Grade A, and why
cf-plan-review 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 — 175 lines — stays where its author put it; the contents beside it link to each section on GitHub.
/cf-plan-review
CLI Requirement: NONE — Works without
coding-friend-cli. Reads the plan folder and writesreview.mddirectly; optional external reviewers are headless CLIs already on PATH. See CLI requirements for the full matrix.
Review the plan: $ARGUMENTS
Purpose
Review a saved /cf-plan folder (not application code) with a fresh, clean-context subagent of the host that is running this skill. Optionally add external reviewers in parallel. Write review.md into the plan folder, then offer to apply Critical/Important findings.
- Unlike
/cf-review: that skill reviews a code diff. This skill reviews the plan document before implementation. - Unlike
cf-reviewer-plan: that agent compares implemented code against the plan. This skill checks the plan itself before any code is written.
Workflow
Step 0: Custom Guide
Custom guide — auto-loaded below (if the raw command shows instead of its output, run it yourself):
bash "<plugin-root>/lib/load-custom-guide.sh" cf-plan-review
If output is not empty, integrate returned sections: ## Before → before first step, ## Rules → apply throughout, ## After → after final step.
Step 1: Resolve the plan and flags
Read docsDir from .coding-friend/config.json (default: docs). Prefer CF_DOCS_ROOT from bootstrap ($MAIN_REPO_ROOT/{docsDir}).
External reviewer flags:
-
Parse
--codex,--gemini,--claude,--cursor,--grok(and--with-<agent>aliases) intoagents=[…]; strip them from$ARGUMENTS. -
Host-match no-op: skip a matching flag only when a
HOST:line exists and equals the flag (the flag matching the current host is skipped). Drop that agent and print:⚠
--<host>skipped: is already the in-session reviewer.No
HOST:line or a different value → do NOT skip. When in doubt, run it.
What remains is <plan>.
If <plan> is empty: list folders in {docsDir}/plans/ newest first (ls -t) and ask which plan to review using a direct user question.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

cf-plan-review is a skill published in the GitHub repository dinhanhthi/coding-friend (3 stars, last pushed 3d ago), licensed MIT. It adds 57 tokens to every session and 2,198 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 2026-09-06.
