Respond to Hermes Context Pressure Before Failure

Long agent runs accumulate conversation history, tool outputs, file excerpts, and intermediate reasoning around a fixed system prompt. Hermes can warn and compress before the model’s context window is exhausted, but compression is a recovery mechanism—not permission to flood the session with unnecessary data.

Identify the source of pressure

Separate fixed overhead from turn growth. Use hermes prompt-size to measure the system prompt, skills, memory, profile, and tool schemas. Then inspect the current workflow for oversized command output, repeated file reads, raw logs, broad searches, image metadata, or long pasted documents.

Compression summarizes earlier conversation into a smaller lineage segment. It should retain goals, decisions, constraints, artifact locations, failures, and next verification steps. When two approaches need independent detail, branch the session instead of forcing both histories through repeated compression.

Pressure-response checklist

• Record the current goal and completion criteria.
• Save important artifacts outside the conversation.
• Reduce command output with targeted filters and pagination.
• Avoid rereading unchanged large files.
• Summarize decisions, not raw logs, into durable notes.
• Measure fixed prompt overhead separately.
• Compress before the session becomes unstable.
• Start a focused branch when an alternative needs its own history.

Preserve verifiability

After compression, restate the acceptance test and live state that must be rechecked. Never assume a compressed summary proves a deployment, file write, purchase, or external message succeeded. Re-open the artifact or query the service when the final answer depends on it.

Common pitfalls

• Treating a large model context as unlimited.
• Pasting full logs when a narrow error window is enough.
• Storing temporary task progress in global memory.
• Compressing before writing critical artifacts to disk.
• Continuing after compression without checking live external state.
• Disabling tools solely to shrink schemas while the task still requires them.

Verification steps

1. Capture prompt-size and current session statistics.
2. Write the goal, constraints, artifacts, and remaining checks in a concise checkpoint note.
3. Compress or branch as appropriate.
4. Ask the resumed session to state the completion contract.
5. Re-open one critical artifact and re-check one external dependency.
6. Finish the original acceptance test and confirm context warnings no longer block progress.
