A local tool that replaces placeholder labels in an analysis with the original names, emails, dates, or other values from a private map. It is the final step after sensitive text has been anonymized for outside analysis.

It helps restore anonymized people, contact details, dates, and similar values in a returned document, report restored and unmatched placeholders, and save the restored text locally.

It lets someone analyze redacted text elsewhere while keeping the real values on their own machine and out of the analysis service.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00166	$0.00947
Opus 5.5	$0.00066	$0.00379
Sonnet 5.5	$0.00033	$0.00189
Haiku 4.5	$0.00017	$0.00095

Security

Grade A, and why

rehydrate 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/rehydrate.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.

confide:rehydrate — restore real values into a placeholder analysis

This is the last step of the CONFIDE round-trip:

Redact locally with confide:anon (default reversible mode) → a GREEN copy with unique reserved-sentinel placeholders ([CONFIDE_PERSON_0001], [CONFIDE_EMAIL_0001], [CONFIDE_DATE_0002]…) plus a secret <name>.map.json (structured: green_sha256, entries[]…) that stays on the machine.
Analyze the GREEN text anywhere — including a cloud LLM. The analysis comes back full of those same placeholders (sometimes mangled to CONFIDE_PERSON_0001, [CONFIDE PERSON 0001]… — but always keeping the full CONFIDE_TYPE_NNNN core).
Rehydrate here: replace every placeholder with its original value from your own map, producing the real analysis — without the cloud ever seeing the originals.

Privacy invariants (do not violate)

Local-only, on the user's OWN map. The map never leaves the machine. This skill never fetches or transmits anything.
Counts only on stdout. The summary reports restored N, unmatched M. The restored text (which contains originals) is written to a local file; it is NEVER echoed to stdout beyond the counts.
Unmatched = possible hallucination. A placeholder that is not in the map is reported as unmatched and left in place — we never invent a value for it. Warn the user that these may be LLM hallucinations.
The <name>.restored.md output contains originals: it is local-only, do not share or commit it.

Run it

python3 skills/rehydrate/scripts/rehydrate.py ANALYSIS_FILE [--map <name>.map.json]

ANALYSIS_FILE — the text/analysis containing placeholders.
--map <name>.map.json — the secret map from confide:anon. If omitted, the sibling *.map.json is auto-found (e.g. an analysis next to session.map.json, or one derived from session.green.md).
--out PATH — output path (default: <name>.restored.md next to the input).
--verify-green <green_file> — check the map's green_sha256 against that GREEN file; warns loudly if they don't match (wrong map for this document).

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.

rehydrate is a skill published in the GitHub repository glebis/claude-skills (409 stars, last pushed yesterday), licensed MIT. It adds 166 tokens to every session and 947 once invoked, about $0.0007 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 2026-08-30.
