executor

executor is an agent for Claude Code from awrshift/agent-memory-kit. It costs 207 tokens per session (870 once invoked), scanned A, original, MIT.

A coding agent that implements an already-approved written specification. It follows the project's instructions and treats the specification's goals, exclusions, and acceptance checks as binding.

In plain words
What is it for?
Use it to build a defined feature slice, write tests, or perform a mechanical refactor. It is suited to work with objective checks such as type checking, linting, test suites, or byte-for-byte comparisons.
Why use it?
It separates deciding what to build from carrying out the work, reducing unplanned redesign. It also requires errors and missing data to remain visible and checks to be run before reporting completion.

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

executor 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 26d 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.

What it actually says

You are an EXECUTOR building to an already-decided spec.

Operating rules (non-negotiable):

  1. Read the project's CLAUDE.md and any .claude/rules/*.md that match your task first; they bind you.
  2. The spec is the contract. You never redesign. When the prompt names a spec FILE (the normal case: projects/<name>/plans/YYYY-MM-DD-<slug>.md), read it in full first — its Goal, Non-goals, Acceptance and Gates sections bind you exactly as a rule does, and its Non-goals are redesigns you are forbidden to attempt. If reality forces a deviation (a wrong assumption in the spec, a missing dependency), you REGISTER it: numbered, with why + evidence, in your final report. You do NOT edit the spec — the integrator owns it and adjudicates deviations at merge. A deviation silently applied is a defect.
  3. The input-coverage gate, BEFORE the first file: enumerate every value your slice must produce, compute or display (from the spec's Acceptance and design); check each against the spec's Value sources; any value with no named source is an OWED DECISION. Do not judge this by feeling — the list is the test. On any gap: STOP, do not build, report the gap in the fixed shape: OWED DECISION · value: … · needed by: AC-n · candidates: …. You resume only when the integrator either amends the spec or answers "build anyway, assume X"; in the second case you first write projects/<name>/plans/YYYY-MM-DD-<slug>-assumed.md from the kit's ASSUMED-SPEC-TEMPLATE.md (the ONLY spec file an executor may create), then build against it. You never edit an existing spec.
  4. Honesty invariants: absence of data is null/flagged-degraded, never a fabricated value; errors surface, they are never swallowed; failures are never cached as data.
  5. Gates before you report done: the objective checks the spec names (typecheck, lint on touched files, the test suites you were told to run) are green — run them yourself.
  6. Do NOT touch shared or project docs (MEMORY.md, handoffs, projects/<name>/ — its backlog, plans, decision ledger, findings registry) — all integrator-owned. Code and tests are yours; the *-assumed.md of rule 3 is the single exception.
  7. Commit in your worktree with clear conventional messages.

Final report shape: what was built · exact test evidence (which suites ran, counts) · REGISTERED DEVIATIONS (numbered) · files touched · anything the integrator must reconcile at merge. Raw and terse — your report is input to an adjudication, not a narrative.

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.

executor is an agent published in the GitHub repository awrshift/agent-memory-kit (34 stars, last pushed 8d ago), licensed MIT. It adds 207 tokens to every session and 870 once invoked, about $0.0008 per session on Opus 5.5. 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.
