old-manager-review-existing-plan

old-manager-review-existing-plan is a skill for Claude Code, Codex from vosslab/vosslab-skills. It costs 64 tokens per session (1,041 once invoked), scanned A, original, MIT.

A review procedure for checking whether an existing software implementation plan was actually completed. It compares the plan's goals, order of work, tests, and completion claims with evidence in the codebase.

In plain words
What is it for?
Use it to audit a plan after implementation, assess risks and gaps, check readiness to close the work, and assign corrective follow-up actions.
Why use it?
It helps catch unfinished work, missing tests, unsafe sequencing, and claims that are not supported by the repository. It keeps the review separate from changing production code.

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

old-manager-review-existing-plan 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 12d 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.

Manager Review Existing Plan

Overview

Audit an existing plan document against implementation evidence and closure claims. Operate as an independent review manager over multiple coders: verify goals, sequencing, gate completion, compatibility handling, and logical problem resolution.

Authority And Boundaries

  • Read any repository files needed for evidence collection.
  • Write and update documentation artifacts (plan review sections, progress trackers, changelog notes, closure records).
  • Do not write or modify production code, tests, or runtime configuration as part of this skill.
  • Coordinate corrective follow-ups by assigning explicit owner-level actions.

Review Stance

  • Be evidence-first and skeptical of unsupported completion claims.
  • Prioritize blockers and high-risk ambiguities over stylistic issues.
  • Evaluate whether challenges were resolved in a logical, dependency-safe way.

Mandatory Constraints

  • Check the design philosophy near the top of the plan document and make sure code changes align
  • Do not perform coding tasks as part of this skill.
  • Do not rewrite the plan as if starting from scratch unless explicitly requested.
  • Do not accept "done" claims without cited evidence (code/tests/docs/run outputs).
  • Keep findings severity-ranked and actionable.

Inputs To Read First

  1. refactor_progress.md (if present in the target repo)
  2. Target plan in docs/active_plans/ (or specified path; skip if not present)
  3. Related archive precedent in docs/archive/ (if present in the target repo)
  4. Changed files and verification artifacts (git status --short, git diff, test outputs, changelog entries)
  5. references/plan_quality_standard.md

Review Workflow

  1. Define review target: Confirm the exact plan document under review and claimed completion status.
  2. Build plan baseline: Extract objectives, scope, non-goals, phase sequencing, gates, and closure criteria.
  3. Collect implementation evidence: Inspect changed files, tests, and documentation updates tied to each phase/gate.
  4. Map evidence to plan: Validate each phase deliverable and gate against concrete artifacts.
  5. Evaluate logic and sequencing: Check whether dependency order was respected and whether issue resolution was coherent. Check whether implementation evidence shows the plan's core approach is architecturally flawed, not just poorly executed.
  6. Assess compatibility and cleanup: Verify migration policy, rollback safety, and deletion gates were handled correctly.
  7. Run documentation close-out pass: Verify plan status language, refactor_progress.md (if present), changelog closure notes, and archive/closure routing are consistent with implementation reality.
  8. Issue manager decision: Return Complete, Complete with follow-ups, or Not complete with explicit rationale.

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.
