What is secrets-resolve?

A configuration utility that replaces environment-variable and file placeholders such as `${env:NAME}` and `${file:path}` with their actual values. It walks through nested objects and arrays and can report missing placeholders.

Use it to resolve environment variables and file contents in merged JSON configuration, optionally allowing missing environment variables with warnings.

It keeps secrets out of shared configuration while still producing a complete configuration for a program to use.

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	$0.00000	$0.00437
Opus 5.5	$0.00000	$0.00175
Sonnet 5.5	$0.00000	$0.00087
Haiku 4.5	$0.00000	$0.00044

Security

Grade A, and why

secrets-resolve 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 2 executable files (_resolve.py, resolve.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.

What it actually says

secrets-resolve (builtin skill)

Role

Resolves ${env:NAME} and ${file:path} placeholders inside a merged config JSON. Emits a new JSON with secrets inlined. Never leaks resolved values to stderr/logs — only placeholder keys (when missing).

Implements implementation.md §M5.3 (simplified for M1: operates on the already-merged config produced by config-resolve, rather than reading .codenook/secrets.yaml directly).

CLI

resolve.sh --config <merged.json> [--allow-missing]

--config required.
--allow-missing: env vars that are not set resolve to "" with a stderr warning (keys only). Without this flag, missing env vars fail hard. File placeholders always fail hard on missing file.

Exit codes

code	meaning
0	all placeholders resolved (or warnings only)
1	at least one unresolvable placeholder / nested use
2	usage error

Placeholder rules

${env:NAME} — reads os.environ[NAME].
${file:path} — reads file, strips surrounding whitespace. Supports relative and absolute paths.
Multiple placeholders per string: all replaced.
Walks into dicts and arrays recursively.
Nested placeholders (e.g. ${env:${env:VAR_NAME}}) are disallowed by design in M1 — they complicate audit/redaction and invite injection.

Security contract

On success (exit 0) the stderr stream MUST NOT contain any resolved value. Only placeholder keys appear in warnings/errors. Test m1-secrets-resolve.bats::SECURITY: enforces this.

⚠️ SECURITY

stdout contains plaintext resolved secrets. Callers MUST NOT pipe stdout into history/logs/dispatch-audit. Pipe directly to the consuming sub-agent or to a file with mode 600 in workspace-private storage only.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

secrets-resolve is a skill published in the GitHub repository cintia09/CodeNook (5 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 437 tokens. 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.
