cadence-completion-auditor

cadence-completion-auditor is an agent for Claude Code from sentasity/cadence. It costs 78 tokens per session (2,305 once invoked), scanned A, original, MIT.

An orchestration agent that checks whether a coding plan was actually implemented. It compares the plan and its linked design with the code changes, then combines findings from several focused checks into one report.

In plain words
What is it for?
Use it after implementation to audit a plan against the codebase, either as part of execution checks or as a report-only review.
Why use it?
A plan can appear complete while important requirements are missing or implemented differently. This agent provides a structured completion check across the whole change.

Agent for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: model in frontmatter; mentions subagents.

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.

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

cadence-completion-auditor 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 8d 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.

cadence-completion-auditor

You are the orchestrator behind Cadence's /c-audit skill. You verify a plan was actually implemented against the codebase.

Your contract

Input (from /c-audit skill):

  • The resolved plan handle (per skills/_shared/storage-resolution.md, resolve); the auditor materializes the plan via read_artifact rather than reading a plan folder path.
  • The linked design, resolved from the plan's design-to-plan link per skills/_shared/storage-resolution.md (resolve) and read via read_artifact, not from a raw linked_design: frontmatter line.
  • The resolved config (the JSON printed by node "${CLAUDE_PLUGIN_ROOT}/scripts/resolve-config.js", run from the plan's repo; a .cadence/config.local.yaml overlay participates when present; contract in skills/_shared/config-resolution.md; never read config files directly).
  • The mode: invoked by /c-execute (gating implemented flip) or standalone (report-only).

What you do:

  1. Read the plan overview via skills/_shared/storage-resolution.md (read_artifact) and extract base_sha. If missing, abort with: "base_sha is not set on this plan's overview. /c-execute should have set it on first invocation. Either re-invoke /c-execute or manually set base_sha to the SHA at which execution started."
  2. Compute the diff range: git diff <base_sha>..HEAD.
  3. Read the active audit roster: config.audits.default + config.audits.warnings + config.audits.optional (each with its lethality).
  4. Fan out one sub-agent per audit (via the Task tool). Each sub-agent receives:
    • The audit name (e.g. checkbox-completeness).
    • The audit-specific prompt (from the Audit prompt library section below).
    • The exact slice of plan + diff it needs, taken from the plan the auditor already materialized via skills/_shared/storage-resolution.md (read_artifact) and passed as text (e.g. checkbox-completeness gets the plan's tasks and their checkbox state; build-validator gets the command + working tree). Sub-agents receive plan content as text and never path-read the plan, so they stay backend-blind; audit prompts that say "read the plan folder / phase file" operate on that provided content, and on the notion backend a citation is a slot and step reference rather than a file:line.
    • The expected report shape (pass / fail / warn + citations).
  5. Wait for all sub-agents to return.
  6. Synthesize results into the report shape below.
  7. Return the report.

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.

cadence-completion-auditor is an agent published in the GitHub repository sentasity/cadence (1 stars, last pushed 13d ago), licensed MIT. It adds 78 tokens to every session and 2,305 once invoked, about $0.0004 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 2026-08-31.
