skill-staged-review

skill-staged-review is a skill for Claude Code from nyldn/claude-octopus. It costs 18 tokens per session (2,885 once invoked), scanned A, original, MIT.

A two-stage review skill for a pull request or feature: first checking whether it matches the requested specification, then checking the code quality. A pull request is a proposed set of changes for review.

In plain words
What is it for?
Use it to compare implementation against success criteria in an intent file, then review the code for quality when the specification check passes or is unavailable.
Why use it?
It separates “did we build the right thing?” from “did we build it well?”, making missing requirements easier to spot.

Skill for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter. Also seen: mentions Codex.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

About the project

Claude Octopus is an orchestration project that sends research, design, and coding tasks to Claude Code and other AI model providers so their results can be compared. Developers use it for multi-model work, disagreement detection, reviews, persistent context, and an optional workflow that moves from discovery through delivery. The catalogue entries are its commands, skills, agents, instructions, hooks, plugins, and settings.

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

skill-staged-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 9d 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.

Two-Stage Review Pipeline

Separates spec compliance (did you build the right thing?) from code quality (did you build it right?). Stage 1 must pass before Stage 2 runs.


Stage 1: Spec Compliance

Validates the implementation against the intent contract.

Step 1: Load Intent Contract

PLAN_STORAGE="${CLAUDE_PLUGIN_ROOT:-${HOME}/.claude-octopus/plugin}/scripts/plan-storage.sh"
OCTO_PLAN_DIR="$("$PLAN_STORAGE" current "$PWD" 2>/dev/null || true)"
INTENT_FILE="${OCTO_PLAN_DIR:+${OCTO_PLAN_DIR}/session-intent.md}"
if [[ -f "$INTENT_FILE" ]]; then
  echo "Intent contract found: $INTENT_FILE"
  cat "$INTENT_FILE"
else
  echo "WARNING: No current resolved intent contract found for this workspace"
  echo "Skipping Stage 1 — proceeding to Stage 2 (code quality) only."
fi

If no intent contract exists: Warn the user and skip to Stage 2. Do NOT fabricate success criteria — the contract must exist from a prior workflow.

Step 2: Validate Success Criteria

For each success criterion in the intent contract:

  1. Read the criterion from the ## Success Criteria section
  2. Find evidence in the codebase that the criterion is met
  3. Mark status:
    • [PASS] — Evidence confirms criterion is met
    • [FAIL] — Evidence shows criterion is NOT met
    • [PARTIAL] — Partially met, gaps identified

Present results:

## Stage 1: Spec Compliance

### Success Criteria Check

#### Good Enough Criteria
- [PASS] Criterion 1: <how it was met>
- [FAIL] Criterion 2: <why not met, what's missing>

#### Exceptional Criteria
- [PARTIAL] Criterion 1: <what's done, what's remaining>

Step 3: Validate Boundaries

For each boundary in the intent contract:

  1. Read the boundary from the ## Boundaries section
  2. Check for violations in the implementation
  3. Mark status:
    • [RESPECTED] — No violations found
    • [VIOLATED] — Implementation crosses the boundary
### Boundary Check
- [RESPECTED] Boundary 1: <confirmation>
- [VIOLATED] Boundary 2: <what violated it>

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.
