context-reset

context-reset is a skill for Claude Code, Codex from dburkart/auto-engineer. It costs 48 tokens per session (721 once invoked), scanned A, original, BSD-3-Clause.

A guide for managing the amount of conversation context available to an automated coding session. It explains when to summarise the conversation, clear it, or restart the process.

In plain words
What is it for?
Use it at the end of an automated development cycle, when old context is causing confusion, or when a clean process restart is needed.
Why use it?
Long coding sessions can retain outdated plans, resolved problems, and old branch details, which may lead to poor decisions. This guide helps start later iterations with relevant information only.

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

context-reset 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 3d 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 — 57 lines — stays where its author put it; the contents beside it link to each section on GitHub.

context-reset

This skill is a reference document, not an executable action. /compact and /clear are built-in Claude Code CLI commands — they cannot be invoked by the Skill tool from within a running session. Reading this skill brings the guidance into context so you can apply the right approach for the situation.

Why context accumulates

Each auto-engineer iteration reads playbooks, fetches issues, reads source files, runs sub-agents, and produces diffs. That context stays in the conversation window across iterations unless explicitly trimmed. After several cycles the window grows large, cache misses become expensive, and prior-cycle residue (old branch names, resolved bugs, superseded plans) can subtly corrupt decisions.

Three options

Situation Action
Normal end-of-cycle, session still healthy, just want to trim cost /compact (built-in)
Prior cycles are actively corrupting decisions — Claude is replaying resolved issues or hallucinating old state /clear (built-in), then restart auto-engineer with explicit --iteration N
Container run requiring a truly clean process (token ceiling hit, env/credential refresh needed) scripts/restart-loop.sh --iteration N (run on the host)

/compact — the default (auto-engineer step 10)

Summarises the conversation in place. The iteration counter, stop-reason history, and current PR state survive in the summary. This is why auto-engineer step 10 calls /compact rather than /clear — the ScheduleWakeup prompt carries --iteration N forward, but the surrounding rationale lives in the summary.

How to invoke: type /compact directly in the Claude Code CLI. It cannot be called from a skill or tool.

/clear — full wipe

Erases the entire conversation. Use only when context corruption is confirmed — you will lose the iteration counter and any uncarried state. After /clear, restart auto-engineer explicitly:

/auto-engineer --iteration <N>

How to invoke: type /clear directly in the Claude Code CLI.

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.

context-reset is a skill published in the GitHub repository dburkart/auto-engineer (5 stars, last pushed 4mo ago), licensed BSD-3-Clause. It adds 48 tokens to every session and 721 once invoked, about $0.0002 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.
