temporal-parameter-staleness

temporal-parameter-staleness is a skill for Claude Code, Codex from PlamenTSV/plamen. It costs 28 tokens per session (2,103 once invoked), scanned A, original, MIT.

A security review guide for multi-step operations whose stored settings or external state may become outdated before completion.

In plain words
What is it for?
Use it to trace request-and-fulfill, lock-and-unlock, proposal, unstaking, and other delayed operations across transactions.
Why use it?
It helps find cases where an administrator changes a duration, limit, or rule after a request starts but before it is finalized, or where changed external state is not checked again.

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

temporal-parameter-staleness 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 7d 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.

TEMPORAL_PARAMETER_STALENESS Skill

Trigger Pattern: TEMPORAL flag (required) Inject Into: Breadth agents, depth-state-trace Purpose: Analyze cached parameters in multi-step operations that can become stale when admin/capability holders change them mid-operation, and external state stored and relied upon without re-verification

Trigger Patterns

epoch|period|duration|delay|cooldown|lock_period|timelock|
unbonding_period|claim_delay|withdraw_delay|maturity_time|
pending_|request_|fulfill_|complete_|finalize_

Reasoning Template

Step 1: Enumerate Multi-Step Operations

Find all operations that span multiple transactions:

Operation Step 1 (Initiate) Wait Condition Step N (Complete) Resource Storing State
{op_name} {initiate_fn}() {wait_condition} {complete_fn}() {PendingRequest / similar}

Aptos multi-step patterns:

  • Request/fulfill patterns: request_withdraw() -> wait for epoch/time -> fulfill_withdraw()
  • Lock/unlock patterns: lock() -> cooldown expires -> unlock()
  • Proposal/execute patterns: propose() -> voting period -> execute()
  • Unstaking: request_unstake() -> unbonding period -> claim()
  • Pending operations stored in Table<address, PendingRequest> or SmartTable or per-user resource

For each multi-step operation:

  • What parameters are read/cached at Step 1 (stored in the pending resource)?
  • What parameters are re-read at Step N?
  • What parameters are used but NOT re-read at Step N?

Step 2: Identify Cached Parameters

For each parameter used across steps:

Parameter Read At Step Stored In Admin-Changeable? Re-Validated At Completion?
{param} initiate() L{N} {PendingRequest.field} YES/NO YES/NO
{param} initiate() L{N} Not stored (read at completion from resource) YES/NO YES (re-read)

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.

temporal-parameter-staleness is a skill published in the GitHub repository PlamenTSV/plamen (281 stars, last pushed 1mo ago), licensed MIT. It adds 28 tokens to every session and 2,103 once invoked, about $0.0001 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 2026-08-30.
