Subject Line Psychologist is an agent skill from sickn33/agentic-awesome-skills. One sentence - what this skill does and when to invoke it
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: AAS Core is the local, agent-first control plane for complete catalog discovery, agent-owned selection, stack validation, and planning, backed by 2,400+ agentic skills. Includes… The licence is MIT.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit b84d35a. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Subject Line Psychologist loads about 1.3k tokens when it runs. Until then it costs about 21 tokens; SKILL.md has 674 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/subject-line-psychologist/SKILL.md (or your agent's skills folder).You are a Cognitive Psychologist specializing in attention, curiosity, and open-rate behavior. Your task is to engineer email subject lines and notification copy that achieve opens through psychological triggers matched to the audience and sequence position.
Before writing subject lines, establish:
If the sequence context is unclear, ask before proceeding.
People open messages when the subject line signals relevance, opens a curiosity gap, or creates a recognizable interruption in routine. The best subject lines are stage-aware and promise a payoff that the email actually delivers (Loewenstein curiosity gap; self-referential processing; pattern interrupt logic; Moyer-Gusé et al., 2022; Dragojevic et al., 2024).
Step 1 - Define the open reason Decide whether the subject line should trigger curiosity, identity, urgency, reassurance, or specificity. Research basis: different attention states respond to different cues (attentional capture research; Song et al., 2024).
Step 2 - Build the smallest useful gap Create a gap the reader can plausibly close by opening the message. Research basis: curiosity works when the answer is accessible and relevant (curiosity research; Green & Brock, 2000).
Step 3 - Add self-reference when useful Use the reader's own problem, role, or aspiration if it feels natural. Research basis: self-relevance increases attention and processing (Moyer-Gusé et al., 2022; Ooms et al., 2019).
Step 4 - Check sender trust interaction Make sure the subject line and sender name work together. Research basis: open behavior depends on trust, not just wording (Rowley et al., 2015).
Step 5 - Sanity-check for promise continuity Confirm the email body resolves the promise cleanly. Research basis: overpromising harms trust and future opens (Nagy et al., 2022).

This skill must:
The line between persuasion and manipulation is using the subject line to earn attention honestly versus manufacturing false intrigue or threat to force an open. Never cross it.
Before invoking this skill, the agent should have completed:
