Honey CCR
The cheapest token is the one not sent. A 500-row log read for one error line costs 500 rows of context. CCR keeps the rows that carry signal and caches the rest — recoverable by hash, so nothing is lost.
Borrowed from headroom's SmartCrusher. Lossy by design — only for data you
skim, never for payloads where every row matters (e.g. a code-review handoff
where the implementer needs all findings; use eson encode losslessly there).
When to use
- A tool returns a uniform JSON array of many records (≥ ~5 items, redundant).
- You need to read it but mostly skim — logs, search hits, metrics, events.
- The full data stays reachable, so dropping the boring middle is safe.
Don't use
- Small arrays (passes through untouched anyway) or non-array data.
- Any array where every element is load-bearing — encode it, don't crush it.
How
tool-that-spews-json | eson crush # → sampled view + sentinel; originals cached
eson retrieve <hash> # → the full original array, verbatim
crush prints the kept sample plus a sentinel
{"_ccr":"<<ccr:HASH N_rows_offloaded>>"}. When you need a dropped row, read the
hash from the sentinel and run eson retrieve <hash>.
- Cache dir:
.honey-ccr/(override withHONEY_CCR_DIR). - Below the size gate,
crushreturns the array unchanged with no sentinel — safe to pipe anything.
Always-on hook (entry-time GC)
While Honey is active, a registered PostToolUse hook applies this automatically to
Bash output — no opt-in per call. Big uniform JSON arrays (≥20 items, ≥2k chars) are
crushed; repetitive text (≥25 lines) gets consecutive repeats collapsed to ⟨×N⟩.
The original is always stashed first, and the rewritten result ends with the exact
eson retrieve <hash> command that restores it. /honey off disables the hook;
history already in context is immutable — this fires at entry, the only place a
hook can act.
Caveat: Claude Code builds affected by anthropics/claude-code#68951 ignore the
hook's Bash rewrite, making it inert (a session-start warning tells you when this
applies). Manual some-tool | eson crush piping is unaffected — prefer it there.

# Honey CCR
The cheapest token is the one not sent. A 500-row log read for one error line
costs 500 rows of context. CCR keeps the rows that carry signal and caches the
rest — recoverable by hash, so nothing is lost.
Borrowed from headroom's SmartCrusher. **Lossy by design** — only for data you
skim, never for payloads where every row matters (e.g. a code-review handoff
where the implementer needs all findings; use `eson encode` losslessly there).
## When to use
- A tool returns a **uniform JSON array** of many records (≥ ~5 items, redundant).
- You need to read it but mostly skim — logs, search hits, metrics, events.
- The full data stays reachable, so dropping the boring middle is safe.
## Don't use
- Small arrays (passes through untouched anyway) or non-array data.
- Any array where every element is load-bearing — encode it, don't crush it.
## How
```sh
tool-that-spews-json | eson crush # → sampled view + sentinel; originals cached
eson retrieve <hash> # → the full original array, verbatim
```
`crush` prints the kept sample plus a sentinel
`{"_ccr":"<<ccr:HASH N_rows_offloaded>>"}`. When you need a dropped row, read the
hash from the sentinel and run `eson retrieve <hash>`.
- Cache dir: `.honey-ccr/` (override with `HONEY_CCR_DIR`).
- Below the size gate, `crush` returns the array unchanged with no sentinel — safe to pipe anything.
## Always-on hook (entry-time GC)
While Honey is active, a registered PostToolUse hook applies this automatically to
Bash output — no opt-in per call. Big uniform JSON arrays (≥20 items, ≥2k chars) are
crushed; repetitive text (≥25 lines) gets consecutive repeats collapsed to `⟨×N⟩`.
The original is always stashed first, and the rewritten result ends with the exact
`eson retrieve <hash>` command that restores it. `/honey off` disables the hook;
history already in context is immutable — this fires at entry, the only place a
hook can act.
Caveat: Claude Code builds affected by anthropics/claude-code#68951 ignore the
hook's Bash rewrite, making it inert (a session-start warning tells you when this
applies). Manual `some-tool | eson crush` piping is unaffected — prefer it there.

Listed tools are metadata hints, not tested compatibility. Agent prompts are suggested handoffs.
Start with one small task
- 1Read the source. Confirm the input, expected output, dependencies and permissions.
- 2Ask your agent for a plan. Approve setup and any costs before running a small isolated test.
- 3Check the output and changed files. Report only what actually ran; keep the source revision for reproduction.
Check the source for dependencies, API keys and third-party costs. A public repository does not mean every service is free.
